This map, in full original hand color, is one of the more remarkable maps produced by the General Land Office. It shows the extent of the Public Surveys just after the Civil War and includes many items of great interest. Most significant are the gold, silver, copper, and other mineral deposits that are color-coded to mark their location. 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 part of the Dakota Territory. In the West, survey progress is still limited with much of Southern California complete, only small areas of New Mexico and Arizona complete, and with no surveys at all in Utah, Montana and Wyoming (here part of Dakota). The geological key also locates via color and icon deposits of quicksilver, iron, tin, asphaltum, coal and oil springs that are shown scattered throughout the country. Constructed from Plats and Official Sources of the General Land Office under the direction of Hon. J.S. Wilson, Commissioner, by Joseph Gorlinski. Signed in the plate by Wilson. The General Land Office (GLO) was created in 1812 to oversee local land offices and in 1849 was incorporated in the Department of Interior. The differences between this lot and the previous lot make an interesting study.
