General Geological Map of Colorado
Incredibly detailed large-format geological map of Colorado published by the Department of the Interior United States Geological and Geographical Surveys of the Territories.
Geographically the map shows from modern day Jensen, Utah (near Horseshoe Bend and Wonsits Valley) in the north west, to Fort Sedgwick in Julesburg in the north east, and from Ute Mountain in Colorado in the south west to Trinidad and east to the border. As well as the major cities marked on the include Denver, Colorado Springs and Cañon City, Silverton, Parrott City, Animas City and Del Norte, the map also marks the Native Reservations and settlements. Iconography across the map identifies the topographical features, major peaks and the developing rail road network.
There are nine varieties of geological formation displayed on the map; Quaternary, Tertiary, Post Cretaceous, Cretaceous, Jura-Trias, Carboniferous, Silurian, Metamorphic Rocks and Eruptive Rocks. The colour key noting which areas these formations are in this region can be found in the upper right corner of the map. There is an accompanying note to say that gold and silver bearing areas are identified by heavy outlining on the map, featuring in the west of the state.
The map cites the geologist in charge of the survey as Dr. Ferdinand Vandeveer Hayden (1829-1887). Hayden was a pioneering geologist best known for this surveying expeditions in the Rocky Mountains, and Yellowstone, Wyoming. Hayden acquired the nickname the "Man Who Picks Up Stones Running”. At the time this would have been the most detailed and up to date survey of the state. The first edition of this map was published in 1877 by the Department of the Interior, United States Geological and Geographical Surveys of the Territories (later known as the General Land Office).
