Not that you asked, but..
Originally BLM holdings were described as... "land nobody wanted" ...because homesteaders had passed them by. (Anyone who has camped at Quartzsite will understand that.) Ranchers hold nearly 18,000 permits and leases for livestock grazing on 155 million acres of BLM public lands. The agency manages 221 wilderness areas, 23 national monuments and some 636 other protected areas as part of the National Landscape Conservation System totaling about 30 million acres.
BLM's roots go back to the Land Ordinance of 1785 and the Northwest Ordinance of 1787. These laws provided for the survey and settlement of the lands that the original 13 colonies ceded to the federal government after the American Revolution. The US Congress directed that they be explored, surveyed, and made available for settlement.
President Harry S. Truman created the BLM in 1946 by combining two existing agencies: the General Land Office and the Grazing Service.
Most BLM public lands are located in these 12 western states: Alaska, Arizona, California,Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington and Wyoming.
