This map, in original hand color, 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 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. Present-day Wyoming is shown as an appendage to Dakota Territory. Signed in the plate and made under the direction of Hon. J.S. Wilson, Commissioner, by Theodore Franks.

Very nice example that is protected in an archival Mylar sleeve. Good impression printed on sound paper with full margins. A hint of toning on one or two folds, spot in Pacific, else fine and remarkable condition for a folding map of this size and period.
