Federal Lands and Indian Reservations of the United States

Abstract: This map layer shows Indian lands of the United States. Only areas of 640 acres or more are included. Federally-administered lands within a reservation are included for continuity; these may or may not be considered part of the reservation and are simply described with their feature type and the administrating Federal agency. This is an updated version of the December 2004 map layer. Purpose: These data are intended for geographic display and analysis at the national level, and for large regional areas. The data should be displayed and analyzed at scales appropriate for 1:2,000,000-scale data. No responsibility is assumed by the National Atlas of the United States in the use of these data.
