Code of Federal Regulations Title 25. Indians § 25.150.9 Land status maps

The Land Titles and Records Offices shall prepare and maintain maps of all reservations and similar entities within their jurisdictions to assist Bureau personnel in the execution of their title service responsibilities. Base maps shall be prepared from plats of official survey made by the General Land Office and the Bureau of Land Management. These base maps, showing prominent physical features and section, township and range lines, shall be used to prepare land status maps. The land status maps shall reflect the individual tracts, tract numbers, and current status of the tract. Other special maps, such as plats and townsite maps, may also be prepared and maintained to meet the needs of individual Land Titles and Records Offices, Agencies, and Indian tribes.
