Landlocked Property and the Checkerboard in Uinta County

Where the checkerboard came from, and how much of the county it covers

Congress's 1862 Pacific Railway Act granted the Union Pacific Railroad every other one-square-mile section of land in a corridor stretching across southern Wyoming, an incentive structure meant to let the railroad sell alternating sections to fund construction while the government kept the sections in between. That 19th-century land-grant math is why a strip of Uinta County today still alternates, section by section, between private and federally administered land in a literal checkerboard pattern visible on any BLM ownership map. Reporting on a major 2023 Union Pacific land transaction put the surface acreage involved in Uinta County at roughly 130,000 acres -- a smaller share of the county than the pattern covers in neighboring Sweetwater County to the east, but still a substantial, real slice of Uinta's land base, concentrated along the railroad's original right-of-way rather than spread evenly countywide.

The practical effect a century and a half later has nothing to do with the railroad itself, which sold off most of its original grant lands long ago -- it's about what happened to legal access once ownership fractured into this alternating pattern. A private section can sit diagonally adjacent to public land at its corners without sharing any actual boundary line with it, and a public section can be almost entirely surrounded by private land with no dedicated public road reaching it. Neither situation is unusual here; it's the default condition across the checkerboarded strip.

What a 2025 federal ruling actually changed -- and what it didn't

In March 2025, the Tenth Circuit Court of Appeals ruled in Iron Bar Holdings, LLC v. Cape that corner-crossing -- physically stepping from one public section to a diagonally touching public section, without your feet or gear ever touching either of the private sections at the other two corners -- does not constitute trespass under federal law. The U.S. Supreme Court denied certiorari in October 2025, letting that ruling stand as controlling law across the circuit, which includes Wyoming. The underlying case arose on a Carbon County ranch, not in Uinta County, but as a Tenth Circuit ruling interpreting federal law, it applies here with equal force.

What the ruling does not do is turn a checkerboarded private parcel into one with guaranteed legal access, or open up vehicle travel across private corners. It covers foot travel between two public sections that meet only at a shared corner point -- nothing about a private landowner's fencing rights, nothing about a private parcel's own access requirements, and nothing about crossing private land by truck, ATV, or horse rather than on foot. If you're evaluating a Uinta County parcel specifically because of its proximity to public land, confirm exactly what kind of access the ruling actually protects for your intended use, rather than treating 'corner-crossing is legal now' as a blanket answer to an access question.

What to actually verify before buying

1. Pull the parcel's full legal description and check it against a current BLM Surface Management Agency map for Uinta County, not an older plat -- checkerboard ownership can and does change hands (as the 2023 transaction shows), so a map that's even a few years old may not reflect current public/private status of a given section.
2. Ask the Uinta County Clerk's office for the parcel's recorded easement history. A deeded, recorded easement across intervening private sections is the only durable way to guarantee vehicle access to a checkerboarded or public-land-adjacent parcel -- proximity on a map is not a substitute.
3. If the parcel itself is checkerboarded private land, confirm whether it has any recorded access easement at all, separate from the public-land-access question -- a private section surrounded by other private sections can be just as legally landlocked as one surrounded by BLM land.
4. For hunting, grazing, or recreational use specifically premised on reaching adjacent public sections, get a written opinion on what the Iron Bar Holdings ruling actually permits for your specific intended activity (foot travel only, versus livestock, ATV, or vehicle access) before assuming it resolves the access question.
5. Ask the BLM Wyoming state office directly whether any public-access easements, rights-of-way, or land exchanges are already recorded or planned for the specific sections bordering your parcel -- these do get negotiated section by section over time.
