1906 USGS Geologic Atlas Bald Mnt/Dayton Cloud Peak/Ft McKinney Wyoming 2 Folios

Description: Geologic Atlas of the United States Bald Mountain-Dayton, Wyoming Folio No. 141 Cloud Peak-Fort Mc Kinney, Wyoming Folio No. 142 by N. H. Darton and R. D. Salisbury, United States Geological Survey; Charles D. Walcott, Director. Washington: Government Printing Office, 1906 A pair of related double folios (2 quadrangles each), both first editions. Library editions. 1) Bald Mountain-Dayton: 15 pp. plus 7 color lithograph maps (2 topographic, 2 areal geology, 2 structure sections and economic geology) and columnar section sheet. Cloud Peak-Fort Mc Kinney: 16 pp. plus 7 color lithograph maps (2 topographic, 2 areal geology, 2 structure sections and economic geology) and columnar section sheet. Both in original tan heavy paper wraps with original black cloth binding strip. Size: 18.5 x 21.75 inches. Map scales: 1 to 125,000. Two early atlases of this northern Wyoming area encompassing most of the Bighorn Mountain range and adjacent portion of the Powder River Basin known for its abundant coal and groundwater resources. These folios are located just west of Sheridan, Wyoming, and include the town of Buffalo, Wyoming. Old folio topographic and geologic maps form an important historical record of the physical and cultural features of the country as they existed and were named (and, in the case of geology, interpreted) over 100 years ago. These maps with accompanying explanatory text are among the earliest of the area surveyed by the USGS and often show a simpler, less well developed and sometimes surprising landscape than is familiar today. These old folios are long out of print and can make wonderful research or conversation pieces. Given the relative rarity of separately published early USGS topographic and geologic maps in the marketplace, the folio series generally offers the best source of maps available to the public for those fortunate enough to have a connection with the surveyed areas. Condition: Complete. Wrappers have a few stray smudges and toning bands at the extremities with old ink stamps above the titles and folio numbers “141” and “142” written in pencil in the bottom left corners. Small portions of the binding strip on the Bald Mountain-Dayton folio have flaked away. Interior text and map sheets are clean and unmarked. Overall, condition is very good. Content: The Bald Mountain-Dayton Quadrangles covers parts of Sheridan, Johnson and Bighorn Counties while the Cloud Peak-Fort Mc Kinney Quadrangles cover parts of Johnson and Bighorn Counties, both in Wyoming. The topo sheets shows the surface physical (hills, rivers, lakes, etc.) and cultural features (buildings, ranches, farms, roads, railroads, towns, localities, ferries, etc.) within about an 1699 square mile area in the Bald Mountain-Dayton quadrangles and 1713 square mile area in the Cloud Peak-Fort Mc Kinney quadrangles. Some of the named places shown in the maps include: Towns: Dayton, Bald Mountain, Beckton, Parkman, Ranchester, Shell, Cloverly, Buffalo, Fort Mc Kinney, Hazelton, Klondike, Greub, Tensleep, and many named ranches and other individual buildings. Railroads: Burlington and Missouri. Of particular interest, the maps show many alpine lakes in the high country, some named, plus at least 4 glaciers at Cloud Peak and Black Tooth (only one remains today). The geologic maps are attractively colored with multiple colors, patterns, shadings, tints, and/or hues used to illustrate the local geologic formations. The economic geology maps show the location of coal-bearing formations, coal mines, and prospects for copper, gold and other metals. In 1894, the USGS implemented a plan to prepare a geologic map of the US in the form of over 3,000 quadrangle atlas sheets issued individually in folio size. The essential parts of each folio were a description of the region surveyed, a topographic map, and an areal geologic map. Additional geologic map sheets and illustrations would be included as determined by the important economic and/or scenic characteristics found in the area. Of the over 3,000 folios planned, only 227 were ever issued before the series was discontinued in 1945. The majority of folios, such as the one offered for sale here, were issued in a library edition containing never-folded, single-sided maps printed on heavy paper with a highly calendared (glossy) surface. This surface was specifically chosen to give the best effects to the patterns and colors. These characteristics make the library edition the preferred choice for collectors and print sellers. Never-folded (and later folded) field editions were also issued but as a portfolio without calendared map surfaces. Shipping: For reasons of size and fragility, your atlas will be shipped flat sandwiched between multiple sheets of new cardboard pads for best protection.
