Request a boundary change

If you own and the map shows it in the wrong place, email us your records and we can redraw it for everyone. Only the claim you ask about changes.

Send these to

• The case number:
• A photo of your ID with everything blacked out except your name. We don't need your address, license number or birth date.
• Proof you hold the claim in the same name: your location notice (the paper recorded with the county and filed with BLM; it says where your corner posts are), or a BLM filing or maintenance fee receipt for this case number. A survey of the claim works too, if you have one.
• Where your corners are, if the papers don't say: GPS readings taken at your corner posts are best.

We check that the name matches the claimant on BLM's record, write down only what we checked and when, then delete your photos and papers.

A redrawn claim is labeled as coming from the owner's records. It is not BLM's record or a survey, has no legal standing, and doesn't settle disputes between claimants. We can decline any request. See the Terms of Use.

How accurate is this map?

This map is only as accurate as the public data behind it.

Claim shapes are approximate. BLM doesn't publish where the corner posts actually are. Most shapes are drawn from the legal description, so a 20-acre claim is often drawn as 160 acres or more, and the real claim could be anywhere inside.

The map can't prove you're on or off a claim. Only the corner posts on the ground and the filed location notice can show that. Check both before you stake or dig, and use a licensed land surveyor if it's close.

An empty spot doesn't mean open ground. BLM can't map every claim, and this data covers federal land only.

Claims and land status come from BLM, and state lines from the Census. None of it is a survey or a legal boundary.

A few claims are redrawn from their owners' records. They're labeled when you tap them, with BLM's outline as a dashed line. That's what the owner showed us, not BLM's record or a survey, and it has no legal standing. See the Terms of Use.
