This map is one of the more remarkable maps produced by the General Land Office. It shows the extent of the Public Surveys in 1866 and is filled with features of great interest. Most significant are the gold, silver, copper, and other mineral deposits that are color-coded 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. Present-day Wyoming is shown as an appendage to Dakota Territory. Made under the direction of Hon. J.S. Wilson, Commissioner, by Theodore Franks. Dated 1866. On 2 sheets, joined.
