In much of the West, including here, buying land doesn't always mean buying what lies beneath it. When the surface and the minerals are owned by different parties, it's called a split estate. Around Gleeson, most of these situations trace back to the Stock Raising Homestead Act (SRHA) of 1916, when the federal government granted surface land for ranching but kept the minerals underneath.
What it means
- You own the surface — your home, your improvements, and your right to use and enjoy your land.
- Someone else may own the minerals — often the federal government (administered by the BLM), sometimes a private party. If your minerals were “severed” before you bought, you never received them — even if your deed doesn't say so.
- The mineral estate is legally “dominant” — the mineral owner has a right to reasonable access to reach and develop the minerals.
But “dominant” does not mean “unlimited”
Government rules place real limits and protections around that access:
- A company must file a plan of operations with the BLM and go through environmental review (NEPA) before significant work.
- It must reasonably accommodate your surface use and minimize damage.
- On SRHA lands, a mining claimant generally must either obtain your written consent or post a bond for surface damage before beginning operations.
- You can negotiate a Surface Use Agreement — access terms, compensation, water protections, and reclamation.

Whether the minerals under your land are federal or privately owned is a title question. See Research Your Parcel for the public county and federal records where you can check it.
