Indian Lands of Federally Recognized Tribes of the United States: 1885 and 2016 Comparison

The 1885 reservation data is depicted on a historic map drawn by Paul Brodie in 1885 for the Commissioner of Indian Affairs, John D. Atkins. (Source: SHSND 973.00497 U5813m 1885) Brodie’s map shows the size and shape of reservations of 1885 which had been established by treaty between the US Government (usually under the auspices of the Commissioner of Indian Affairs) and a particular tribe. The historic map drawn by Paul Brodie was scanned. The reservation boundaries were georeferenced then digitized from the scanned image to produce the 1885 reservation boundary layer portrayed on this map.

Indian Land Areas Judically Established 1978 and American Indian Reservations

Judicially established Indian lands are based on information provided by the Indian Claims Commission. The Indian Claims Commission was established by Congress in 1946 to settle land claim disputes between American Indian s and US Government. This map portrays the 1978 judicially established American Indian land areas that resulted from the cases before the US Indian Claims Commission or US Court of Claims in which an American Indian tribe proved its original tribal occupancy of tract within the continental US. These areas are shown in relation to the federally recognized tribal entity boundaries last updated in 2016 along with the Bureau of Indian Affairs (BIA) and regional office locations. The source of this data is from the 1993 US Geological Survey (USGS) map ‘Indian Land Areas Judicially Established 1978’ (original 1:4,000,000 scale, Albers projection). Each tract is outlined with a solid maroon line. The number on each tract refers to the Indian land area map index in the commission’s final report.
