[ Territory of Colona | Territory of Jefferson ]
[ Views of Colorado ]
![]()

An important map of the Kansas Territory, one of the first maps to name Denver and the only atlas maps to show the full Kansas Territory on an individual sheet (though the western-most edge of the territory is not shown). Kansas Territory was created in 1854, running between the 37th and 40th parallels between Missouri and the Continental Divide. Most of the development in the territory took place in the eastern part until late 1858 when gold was discovered at the confluence of the Platte River and Cherry Creek. This precipitated the "Pike's Peak" gold rush of 1858-60, which led to the establishment of the temporary town of Montana and the two settlements of Auraria and Denver City on either side of Cherry Creek (these would combine to form Denver in April 1860). All three of these gold rush communities are shown on this map, one of the first to reflect the Pike's Peak gold rush.
The map shows the development, in terms of counties created and settlements established, in the east, with information in the western part mostly historical and topographical. The many rivers in the region are noted, as are the routes of a number of explorers, including Fremont, Emory, Peck, Merrit and many others. The Indian tribes of the plains (which at the time were the primary inhabitants) are noted, as are Indian battle sites and forts. The foot hills of the Rockies are shown with some detail, a large "Gold Field" printed there. This is a very rare map, this version of which probably published in S. Augustus Mitchell's Universal Atlas of 1860. A seminal map of the Kansas Territory and Pikes Peak Gold Rush $3,850

C.H. Deforrest, Jr.. "Map of the Gold Region with the Routes Thereto." From Harper's Weekly. New York, April 2, 1859. 4 1/8 x 7 3/8. Wood engraving by N. Orr. On full sheet with text, "How to get to Pike's Peak Gold Mines." Very good condition. Denver.
A nice example of the earliest generally available map of the Pike's Peak Gold Rush. When gold was discovered in the autumn of 1858 in the western part of the Kansas Territory, along the Rocky Mountain foothills near what is today Denver, the news created a great stir in the settled parts of Kansas and Nebraska along the Missouri River, as well as further east. This led, in early 1859, to what became known as the "Pike's Peak Gold Rush," in which thousands of hopeful prospectors traveled from cities such as Omaha, Des Moines, St. Joseph, Lawrence, and Kansas City across the plains to the "gold fields." This rush inspired a number of Pike's Peak guides and maps, describing and illustrating the routes to take.
One of first such guides, issued in February, was Byers and Kellom's Hand Book to the Gold Fields of Nebraska and Kansas, which included a small map drawn by D.H. Deforrest Jr. and engraved on wood by N. Orr. This map shows the main northern (following the Platte River) and southern (following at first the Arkansas River) routes. At the time, there were two main gold rush towns, Auraria and Denver City (which were to merge as Denver in early 1860) on either side of Cherry Creek where it empties into the South Platte. The creek is shown on the map, as is Auraria, but there is no mention of Denver.
The map from the Byers and Kellom guide was reissued within two months in Harper's Weekly from the same block (of which this is a nice example). This example of the map is accompanied by an article on "How to get to Pike's Peak Gold Mines," which ends with the prophetic words, "From present appearances, the rush to Pike's Peak will be tremendous." The Deforrest map subsequently appeared in a number of issues the Rocky Mountain News, a paper founded by one of the authors of the original guide, William N. Byers, in April 1859. The map was also issued on a broadside. This is thus a very early example of a map which played a not insignificant role in the early dissemination of information about the gold rush. $375

"Kansas, Nebraska, Minnesota, Indian Territory, Dacotah. From Smith's New Geography, by Roswell C. Smith. Philadelphia: J.B. Lippincott and Co., 1860. 12 x 10. Lithograph. Original hand color. Light stain in right margin, just into border. Otherwise, very good condition. Denver.
An excellent map of the American plains just before the Civil War, one of the very few maps to show the Jefferson Territory. The year before this map was issued, the Pike's Peak gold rush brought thousands of prospectors and others to the front range in and around "Denver City" and "Auraria" (which are both shown on this map, issued the same year they were merged into one city). These settlers felt that the government of the Kansas Territory, in which they were located, was too distant and disinterested, so they formed a provisional government of a proposed territory of "Jefferson," sending a delegation to Congress to have the territory established. This government operated for a couple years, though it was never recognized by Congress, and it does appear on a very few maps issued at the time, including on this map.
Also of interest on this map is the information related to both the western emigration going on at the time and the Pike's Peak gold rush. Beginning in the 1850s, with the California gold rush and the acquisition of the lands from Mexico, it became obvious that a trans-continental railroad was needed, but there was no agreement over the route to be taken. This map shows five proposed routes, including essentially the one that was completed as the Union Pacific Railroad within the following decade. The map gives good detail on the rivers and Indian tribes through the area depicted, as well as the forts scattered from Forts Union and Benton in the north to Fort Towson just north of Texas. The layout of the mountains in the area was not that well known at the time, but an attempt to depict this is also made on this fine map. $375

"The United States 1861." From Our Whole County. Cincinnati: Henry Howe, 1861. 4 3/8 x 6 3/4. Wood engraving. Original hand color. Some smudging in margins. Else, very good condition. Denver.
An unusual map of the United States in 1861 from a uncommon account of the country early in the Civil War. The states of the Confederacy are shown in green, while those which supported the Union are shown in red. The territories are indicated in yellow. The capitals of each state is indicated, and rivers and some topography is shown. What is most interesting on this map is the very elongated shape of Colorado Territory, just created the year this map was made and with Denver City and Pike's Peak noted. Colorado was mostly taken from the eastern part of Utah and the western part of Kansas, the latter here shown in greatly truncated size. Colorado's eastern border is at 104 degrees west, but on this map it is put at approximately 100 degrees west! $75

W.H. Gamble. "Map of Kansas, Nebraska and Colorado Showing also The Eastern portion of Idaho." Philadelphia: S. Augustus Mitchell, Jr., 1863. 11 1/2 x 14. Lithograph. Full original color. Very good condition. Denver.
A fine of the Plains states from Philadelphia publisher S. Augustus Mitchell Jr.. It shows the territories of Kansas and Nebraska shortly after they were reorganized into their present borders (though they were still territories for a number of years yet). Their reorganization was started with the creation of the territory of Colorado in 1861. This territory was formed because of the huge population which had emigrated to the foothills of the Rocky Mountains in the "Pike's Peak Gold Rush." When gold was discovered at the junction of Cherry Creek and the South Platte in 1858, tens of thousands flooded to the area over the next couple of years, creating the towns of Denver City and Auraria (the two which joined together to form Denver), as well as Boulder, Golden, Central City, Breckinridge, all of which are shown on this map in the "Gold Region."
Colorado was created to a great extent from the western part of Kansas, which thus was shrunk to its current size. Nebraska also lost some land to Colorado in 1861, but it was mostly reduced that year by the organization of the lands north of 43° N as the Dakota Territory. The last change to its borders, the year this map was issued, occurred when the western part of both Dakota and Nebraska were subsumed in the new territory of Idaho. This was a period of the planning of the trans-continental railroad and Mitchell shows a number of the considered routes with dashed lines. This map was issued at a time when this region was flooded by settlers, miners and emigrants seeking new opportunities in the burgeoning American West. The eastern-most parts of Kansas and Nebraska are shown fairly well settled, and in the west are shown a few new settlements, forts, and Indian tribes. With updated maps in most atlases, Mitchell pictured this fascinating part of American history at a transitional stage. $250

"Johnson's Nebraska, Dakota, Colorado, Idaho & Kansas." New York: Johnson & Ward, 1863. 12 3/4 x 15 1/2. Lithograph. Original hand coloring. Very good condition.
A detailed map of northern plain states (present-day Kansas, Nebraska,Colorado, the Dakotas, Wyoming and Montana). This map shows a configuration of this region which lasted only for one year. In 1863,the eastern part of Washington Territory and the western part of Dakota Territory were broken off to form the Idaho Territory, encompassing what today is Idaho, Montana and Wyoming. The next year the eastern part of this huge Idaho Territory, that shown here, was broken off to create the Montana Territory, with the southeastern part temporarily going back into the Dakota Territory. The detail in this map is most impressive, showing rivers, towns, forts, Indian tribes, and the early trails which criss-crossed this region. This map was issued during the Pike's Peak gold rush, so the four main routes to "Auroria" are shown, the distances of the northern and southern-most routes noted on the map. The gold rush towns of Auraria, Denver, and Montana are all shown, though the first two had by then merged into Denver. $250

F.W. von Egloffstein after surveys by John N. Macomb. "Map of Explorations and Surveys in New Mexico and Utah...by Capt. J.N. Macomb Topl. Engrs...1806." New York: Geographical Institute, 1864. 30 3/4 x 37 1/4. Tinted aquatint engraving. Some separation and very light discoloration at folds. Overall, very good condition. Wheat: 983. Denver.
A nice example of what Carl Wheat called "one of the most beautiful maps ever published by the Army," a map that "is a landmark map for various regions." It shows the region around the "four corners" in the American Southwest, based on surveys from an 1860 expedition led by Captain John N. Macomb to explore the Old Spanish Trail from New Mexico towards Utah. The expedition is important in its confirmation that the Green and "Grand" (now Colorado) Rivers joined to form the Colorado just above the Grand Canyon. The map was printed in 1864, but didn't actually get published until 1875 because of the Civil War.
Wheat's comments on its importance is not only based on its geographical significance, but also because of its documentation of the routes of various explorer's routes, including Macomb's as well as those of Gunnison, Marcy, and Father Escalante and others. The last factor in Wheat's judgments is it striking appearance, where it looks almost three dimensional. This is the result of a technique of depicting topography developed by F.W. Egloffstein, where his intent was to "give his map the appearance of a small plaster model of the country." This was achieved by applying very fine lines on the plate by use of a ruling machine (done by Samuel Sartain), which were then exposed to acid to varying degrees to achieve the desired appearance. Only a few maps where made using this difficult process and this is the finest example thereof. The map is a wonderful depiction of the main drainage areas of the American Southwest, as well as many other features such as pueblos, archaeological sites and settlements, all conveyed with a remarkable appearance that few other maps have every matched. $1,800
Johnson's map issued a year later than that above. Though the eastern border of Nevada was changed to the 114th meridian the year this map was issued, the old border is shown here. The many trails that were beginning to be used in the west, such as the Cimarron, Santa Fe, and Oregon trails, are indicated, as are the different routes leading to the "Pike's Peak" gold mining regions around Denver. This map was issued in the early days of the building of the trans-continental railway and the proposed routes for the southern Pacific R.R. and both the Central Pacific R.R. and the Union Pacific R.R., which are shown on this map passing each other by, rather than meeting in Utah as they eventually did. $325

W.H. Gamble. "Map of Kansas, Nebraska and Colorado Showing also The Southern portion of Dacotah." Philadelphia: S. Augustus Mitchell, Jr., 1867. 11 1/2 x 14. Lithograph. Full original color. Very good condition. Denver.
A revised version of the Mitchell map of the Plains States (cf. above). A year after Idaho was created as a huge territory, the northeastern part of this territory became Montana and the southeastern part, shown in the upper left of this map, was "Attached to Dacotah." $225

"County Map of Dakota, Wyoming, Kansas, Nebraska and Colorado." Philadelphia: S. Augustus Mitchell, Jr., 1870. 20 x 14 3/4. Lithograph. Original hand color. With old repairs at centerfold separation. Otherwise, very good condition. Denver.
This map shows the northern plains at a time when the railroads were opening up the region to new settlement. Completed in 1869, the transcontinental railroad ran across the center of the area shown here, from Omaha to the South Pass in western Wyoming. The railroads facilitated the movement of emigrants through and into this area--already begun by the emigration to Oregon, the California Gold Rush and Pike's Peak Gold Rush(noted on this map as "Gold Region"). This led to the creation of new states, such as Kansas (1861), Nebraska (1867), as well as territories such as Colorado, Dakota, Montana, and the just created Wyoming (1869).
This detailed map provides a good topographical picture of the region, with the rivers and mountains depicted, as are the locations of the plains Indian tribes which played such an important (and tragic) role in the opening of the west. The maps also well represents the development of this region, picturing towns, forts, roads and trails. Of particular interest is the depiction of the railroads, which are indicated sometimes following the early routes of explorers, also shown on the map. The Union Pacific Railroad, completed just the year before this map was published, is shown running through Nebraska to Cheyenne and then west, while the two railroads into Denver-one to Cheyenne to meet the Union Pacific and one directly east to Kansas City-both completed just the year this map was issued, are both shown. This is a fine map of the classic "Wild West" of popular lore. $185

"Colton's Utah & Colorado." New York: G.W. & C.B. Colton, 1872. 12 3/4 x 15 1/2. Lithograph. Original hand color. Some minor chips and tears at edges, but overall very good condition. Denver.
A rare map showing the territories of Utah and Colorado together, appearing only in a couple years of the Colton atlas. This map was issued shortly after Denver became connected by rail to the East and with the trans-continental railroad, the beginning of a period of considerable growth in Colorado. In 1870, Denver the Denver Pacific line was completed from Denver to Cheyenne, through which ran the Union Pacific Railroad. That same year, the Kansas Pacific completed their line from Kansas City to Denver across the Prairies. This map show both these lines, the trans-continental railroad, as well as the Denver & Rio Grande to Pueblo and then Canyon City and another line from Denver to Georgetown. The political depiction in the two territories is interesting. Utah has considerable development in the area around Salt Lake City and the Great Salt Lake, while most of the south east is broken into only four counties. Colorado has only two large counties in the northwest, Lake and Summit, which are characterized on the map as "Elevated plain, fertile, gently rolling with fresh water lakes and timber." Quite a bit of information is given for southern Wyoming, including Fort Laramie and the South Pass. A rare map for the collector or anyone interested in the history of the central Rockies. $285

"County Map of Colorado, Wyoming, Dakota Montana." Philadelphia: S. Augustus Mitchell, Jr., 1874. 19 1/2 x 14. Lithograph. Original hand color. Very good condition. Denver.
A later version of the Mitchell map of the northern plains states (cf. above), which is shifted slightly to the northwest, leaving off Kansas which appeared on the earlier version. The reason for that was the establishment of Yellowstone National Park in 1872. On the earlier map, the western parts of Wyoming and Montana (then almost totally unsettled) were not included, but this map shows as far as the headwaters of the Yellowstone River and includes a depiction of the new park. The map also shows the considerable development of Colorado, which was in the middle of the silver boom. New towns and railroads are depicted, providing a good picture of the territory just two years before statehood. $225

"Colorado." Philadelphia: O.W. Gray, 1876. 12 x 14 3/4. Lithograph. Original hand color. Very good condition. Denver.
An early map of Colorado, issued the year of statehood. It was published by the Philadelphia firm of O.W. Gray which began its publishing around mid-century and published regional and U.S. atlases up to the 1880s. It shows the state's counties, except for San Juan country created the year the map was published. The Ute Indian reservation in the western part of the territory is shown, as is the 1873 San Juan Purchase of lands from the reservation necessitated by the discovery of silver there. The township surveys along the front range are shown, as are the railroads rapidly being built, coming into Denver, to Pueblo, and into the mountains for the mining towns. Gray updated the map to show the arrival of the Atchison, Topeka and Santa Fe Railroad to Pueblo in 1876, and its extension almost to Fort Garland. CS On Approval
F.V. Hayden was commissioned by the U.S. Government to map large parts of the American West. He and his team surveyed Colorado between 1873 and 1876, mapping all of the territory-including its immense mountainous regions-for the first time with accuracy and unparalleled detail. This resulted in his landmark Geological and Geographical Atlas first issued in 1877. This included a few general maps, a series of regional maps showing impressive detail of topography, drainage, railroads, roads and mineral resources, and some charts showing the geological strata of the state.

An early map of Colorado, issued just three years after statehood. It was published by the Philadelphia firm of O.W. Gray which began its publishing around mid-century and published regional and U.S. atlases up to the 1880s, first as O.W. Gray and then O.W. Gray & Son. This map is typical of their work, presenting the latest information available with clear and precise detail. Development in the state at the time was focused on the Denver area and mining sites in the eastern Rockies. The map is interesting in showing how the railroad network served these places, with a number rail lines converging on Denver and others extending to Leadville (center of the Silver boom which began in 1879) and towards Gunnison. A nice picture of the state at an important period in its growth. CS On Approval

"County Map of Utah and Colorado." Philadelphia: W.M. Bradley & Bro., 1881. 8 x 11. Lithograph. Original color. Very good condition. Denver.
A neatly detailed map from the Philadelphia publishing firm of William M. Bradley & Bros. While Philadelphia was no longer the main center of cartographic publishing in North America by the late nineteenth century, many fine maps were still produced there, as is evidenced by this map. Topography, political information, towns, and physical features are all presented precisely and clearly. Particular focus is on the many railroads, which were essential in the development of these states. The Union Pacific, which ran across the southern part of Wyoming into Utah, is shows, including its connections to Denver and other Colorado locations. $125

H.L. Thayer. "Thayer's Map of Colorado." Denver, CO: H.L. Thayer, 1882. Separately issued map on bank note paper, folding into original gold stamped covers. 24 1/2 x 28. Lithograph by J. Bien & Co. Original hand color. With some repaired separations at folds. Otherwise, very good condition and bright color. Denver.
The culminating map of Colorado from one of the earliest map publishers in Denver. Thayer, a Civil War veteran, established his map business in Denver in 1871. In 1876, he was in partnership with Frank P. Swindler (great name!) publishing maps and dealing in real estate, but by the end of the decade he was back on his own. He issued a series of maps of Colorado; the first was in 1871 and this is the last and most detailed. Based on the 1881 General Land Office map, this is, as Ellis says in Colorado Mapology, "a very good map," filled with copious details. The underlying information on rivers, towns, mountains and railroads is impressive and on top of this, Thayer shows the counties, Ute Reservation, military reservations, and the land office districts, outlined in blue. As a separately issued map, printed on bank note paper and folded into cloth covers, this map is as rare as it is historically fascinating. $3,800

"Map of Colorado." Chicago & Toledo: H.H. Hardesty & Co., 1882. Lithographic transfer from engraving. Original color. 13 1/8 x 19 1/4. Chip in bottom left margin. Otherwise, very good condition. Denver.
A nicely detailed map of Colorado from an unusual series of maps issued in Chicago and Toledo towards the end of the nineteenth century. During this period there was a growing interest in travel and business throughout North America, and publishers saw this as an opportunity for issued detailed and accurate maps of the states and provinces. The maps from this series, issued by Hiram H. Hardesty & Co., are typical of period, with detail including roads and railroads, small towns and large cities, rivers and lakes and much other topographical information. As claimed on the title page, these maps were created from images originally created in copper plates. The detail here is very good, with emphasis on the myriad railroad lines criss-crossing the state, including those leading to the silver mining towns, such as Leadville and Breckinridge, for the Silver Boom had begun just four years earlier. $150

"Tunison's Colorado." Jacksonville, Illinois: H.C. Tunison, 1885. 9 3/4 x 12 1/8. Original hand outline color. Very good condition. Denver.
A handsome map of Colorado from Tunison's Peerless Universal Atlas. With the development of wax engraving (cerography), more maps and atlases were able to be produced in cities beyond the major centers of New York, Philadelphia and Chicago. Henry C. Tunison issued a series of fine atlases beginning in 1885 and lasting into the beginning of the twentieth century. This is a nice example of his output, showing Colorado within a decade of statehood, shortly after the great silver strikes at Leadville and a period when mining was booming. This up to date map is an excellent snap-shot of the state at this early and important period. $125

"Colorado." Philadelphia: W.M. Bradley & Bro., 1889. 16 x 22. Lithograph. Original hand color. Very good condition. Denver.
A precisely detailed map from the Philadelphia publishing firm of William M. Bradley & Bro. While Philadelphia was no longer the main center of cartographic publishing in North America by the late nineteenth century, many fine maps were still produced there, as is evidenced by this map. It shows the state with impressive detail, with emphasis on rivers, towns, and the myriad railroad lines criss-crossing the state. Some indication of mountain ranges and major peaks is also given with hatchuring. $175

Edward Rollandet. "Rollandet's Map of the City of Denver. Fourth edition-February 1st. 1889." Denver: E. Rollandet, 1889. Separately issued map, missing covers. 33 x 32 1/2. Photolithograph by Julius Bien. Original color. A few breaks at folds; archivally repaired. Else, very good condition. Framed to museum standards. Denver.
A very detailed map of Denver, "compiled, drawn and published by Edward Rollandet." Rollandet was a Denver map publisher who issued a series of maps of Denver from about 1886 to 1905. This was a separately issued map, folded so it could be easily carried and used. The map is excellent, its large size allowing for great detail. Streets, buildings, parks, creeks, rivers and lakes, canals, property owners, farms, and rail, cable cars and much else is clearly presented. Attractive vignettes are included showing the Windsor Hotel, Albany Hotel, Essex Building and Johnson Block. A very rare historical document of Denver near the end of the nineteenth century. $2,600

"Colorado." From Gaskell's Atlas of the World. Chicago: Unknown, 1887. 9 5/8 x 12 1/4. Engraving. A colorful map with full borders. Very good condition. Denver.
Towns, railroads, topography and more are all clearly presented on this detailed map. The thirty-nine counties at the time are shown in contrasting pastel shades. Oregon on reverse. $65
"Denver and Rio Grande Railroad System." Chicago: [1888?] Colored cerograph. 14 x 17 1/2. Some repaired separations at folds. Very good condition. Denver.
This detailed map delineating three types of railroads in Colorado, eastern Utah, and a small part of New Mexico. Red lines show standard gauge, blue lines narrow gauge, and red and blue together stand for three rail. Modelski's Railroad Maps of North America (pp.96-7) illustrates a similar map containing an 1883 date, but this map shows considerably more lines, especially for the mining towns of Colorado. The map was probably issued to accompany a railroad schedule booklet dating from the late 1880s. An inset map in the lower left shows the Central Pacific Railroad route from San Francisco to Colorado. $325

"Tunison's Colorado." Jacksonville, Illinois: H.C. Tunison, 1889. 9 3/4 x 12 1/8. Original hand outline color. Some light smudges in bottom left corner; else very good. Denver.
An updated version of Tunison's Colorado (cf. above), with the fourteen new counties, added in 1889, illustrated. $125

Louis Nell. "Nell's Topographical Map of the State of Colorado." Denver: Hamilton & Kendrick, 1896. Separately issued map, folded into original covers. Dissected and mounted on fabric backing. 28 3/8 x 40 1/2. Lithograph. Original hand color. With original cover and index (separated). Some light surface smudging; overall, very good condition. Denver.
Louis Nell's famous and important series of maps of Colorado, begun in 1880, were not only issued in Crofutt's Guide (cf. above), but also as separately issued maps folding into covers with an index. This is a nice example of one of those rare pocket maps, published in 1896 by Hamilton & Kendrick. According to this firm's blurb on the inside front cover, "This Map of Colorado has been compiled from all available surveys in existence, it is consequently the most complete and accurate one ever published, and shows all the information useful to settlers, miners and travelers." The amazing amount of geographical and topographical information includes mining camps, railroads, canals, roads and mountain trails. Also timber preserves, altitudes of mountains, passes, stations and myriad towns. This is a nice example of one of the seminal cartographic depictions of Colorado. $1,800

[Colorado.] Chicago: Rand, McNally & Co., 1899. 19 x 26. Cerograph. Full original color. Very good condition. Denver.
A late nineteenth century map from the early days of the Rand, McNally & Co. firm out of Chicago, a company that would shift the center of cartographic publishing from the east coast to the mid-west. Typical of the firm's work, this map has very good detail, precisely and neatly exhibited. Social information, counties, roads, and many more is neatly illustrated. The firm is known for being able to depict copious data in a clear manner, and on this map that is well demonstrated by the depiction of the impressive topography of the Rocky Mountains. Aesthetically and cartographically, it foreshadows the maps of the twentieth century. $150
"Colorado." 1901. 10 1/4 x 12 5/8. Cerograph. Small stain in corner of upper left margin. Denver. $45

A.F. Dinsmore. "State of Colorado. Compiled from the official Records of the General Land Office and other sources." Washington: General Land Office, 1905. 29 x 34. Color lithograph. Backed on linen. Very good condition. Denver.
The U.S. General Land Office (GLO) was established in 1812 with responsibility to survey and control the dispersal of public lands. All public land was required to be surveyed prior to settlement, and the first director of the GLO, Thomas Hutchins, set up a systematic process of rectangular survey for the public lands and launched the great national project to survey and map the public domain in the entire country, a procedure which got under way in the famous "seven ranges" of southeast Ohio. Each surveyor was to record not only geography, but also features of the landscape with economic import, such as roads, Indian trails, existing settlements, Indian lands, mineral deposits, and of particular interest, railroads and their rights of way. Of note is that unlike most surveys of the time, the surveyors were instructed not to apply new names to the landscape, but to use "the received names of all rivers, creeks, lakes, swamps, prairies, hills, mountains and other natural objects."
The GLO continued to publish excellent maps into the 20th century. They almost always were the most accurate and detailed maps of their day, and this separately issued map of Colorado is an excellent example of their output. It has an underlying but clear depiction of the complex topography of the state, with the county and land district boundaries overlaid. Also indicated are forest, private lands, as well as Indian and military reservations. While roads are not indicated, rivers, lakes, towns, and the myriad railroads in the state are all precisely shown and named. Along the top are inset maps of Denver, Cripple Creek and Leadville. $650
"Map of Colorado." Denver: The Clason Map Co., 1908. Separately issued map, folding into original booklet, entitled Clason's Highway Map of Colorado. Lithograph in two colors by the Denver Lith. Co. 30 1/2 x 40. With hole in top margin and minor separation at some folds. Overall very good condition. Denver.
An excellent folding, road map of Colorado from the beginning of the twentieth century with its booklet containing an index of Colorado towns, rivers, mountains and other useful information. The map is on a quite large scale, 1 inch = 10 miles, so the detail is impressive. Roads, railroads, wagon roads and mountain trails are all shown and physical features are also clearly noted. Such maps, intended for use, did not survive in very large numbers, especially in such good condition. $175

H.C. Woods after R.D. George. "Geologic Map of Colorado." Boulder: Colorado State Geological Survey, 1913. Colored wall map backed on linen. With some wrinkles and cracking to surface, and wear at edges. Still, colorful and striking appearance. Denver.
A very large and very detailed geological map of Colorado issued by the state geological survey in 1913. The map was drafted by H.C. Woods and prepared by R.D. George based on various geological surveys of the state, including that by Hayden. Along the right edge is a key explaining the colors on the map, each reflecting a different geological form. Striking and quite rare, this is an unusual map of Colorado. $650
U.S.G.S. "Rocky Mountain National Park Motorists Guide." Washington: Department of the Interior, 1937. Folding map. 28 x 24 3/4. Cereograph with printed color. Very good condition. Denver.
A terrific "motorists guide" to the Rocky Mountain Park. The main section is a topographical map of the park with excellent detail of all the peaks, creeks, lakes, trails, and the paved and unpaved roads. Two other maps are included, one showing "All Routes" to the park from Denver, Fort Collins and the Front Range, and a map showing automobile routes to the region from a larger area, extending from Glacier National Park in the north and Mexico in the south. At the bottom is a table with a list of the hotels and their rates and two vignette scenes promoting keeping the park clean and preventing forest fires. On the back is text about the park from the Department of the Interior. $125
