Antique Map Auction Sale No. 110 - closed 3/2/2005
This map is one of the more remarkable maps produced by the General Land Office. It shows the extent of the public surveys and many items of great interest. Most significant are the gold, silver, copper, and other mineral deposits that are color-coded to mark their location and keyed to the legend. The sites of army forts and posts provide an excellent view of the undeveloped territories and the western frontier. Details include land grants, townships, subdivisions, railroads, mining districts & etc. This is the first issue to show the newly formed Wyoming, which was previously shown as an appendage to Dakota Territory. Made under the direction of Hon. J.S. Wilson, Commissioner, by Theodore Franks. Signed in the plate by Wilson.
