Map of BLM Lands and State Office Boundaries.jpg

This is a reference map issued by the Bureau of Land Management (BLM) displaying the National Land and Subsurface Ownership across the United States as of December 31, 2025. The map delineates three categories of land ownership: BLM Surface Ownership shown in yellow, BLM Administrative State boundaries shown with brown outlines, and Federal Subsurface Mineral Estate shown with diagonal hatching patterns. The BLM maintains significant surface ownership across the western United States, with substantial holdings concentrated in Montana, Wyoming, Utah, Colorado, New Mexico, Idaho, Nevada, California, Arizona, and Alaska. Federal subsurface mineral estates are indicated throughout various western states, particularly in Montana, Wyoming, Utah, and Colorado, representing areas where the federal government retains mineral rights beneath surface lands that may be privately or otherwise owned. The map includes scale measurements in both miles and kilometers, and a disclaimer noting that the BLM makes no warranty regarding the accuracy, reliability, or completeness of the map or displayed data for individual or aggregate use with other data. This document serves as an informational resource for understanding federal land management jurisdiction and mineral rights distribution across the nation.
