In a decision that reverberates across the American West, the U.S. Supreme Court has declined to hear an appeal in a pivotal ‘corner-crossing’ case, effectively upholding a lower court’s ruling that affirms public access to landlocked public lands. The Supreme Court’s decision not to review the case means that the legal precedent established by the 10th U.S. Circuit Court of Appeals will stand, allowing individuals to traverse private property corners to reach adjacent public land parcels, provided they do not physically touch the private property.
This significant legal news secures access to an estimated 3.5 million acres within the six states under the 10th Circuit’s jurisdiction: Wyoming, Colorado, Utah, New Mexico, Kansas, and Oklahoma. The broader implications touch upon an estimated 8.3 million acres of land across the West that are considered ‘corner-locked.’
Understanding ‘Corner-Crossing’ and the Checkerboard West
The controversy surrounding ‘corner-crossing’ stems from a historical land management practice dating back to the 19th century. The federal government, in its efforts to encourage westward expansion, granted vast tracts of land to railroad companies. This policy resulted in a distinctive ‘checkerboard’ pattern of land ownership across much of the West, where alternating sections of public and private land meet at precise corners. This arrangement frequently leaves parcels of public land entirely surrounded by private property, rendering them inaccessible without permission from the landowner.
‘Corner-crossing’ is the method by which individuals can step diagonally from one public land parcel to another, precisely at the point where four different parcels—two public and two private—converge at a single corner. This maneuver is considered legal by advocates if it is done without any physical contact with the intervening private land. For decades, the legality of this practice existed in a legal gray area, often treated as trespassing by landowners, creating a significant barrier to public land access for hunters, anglers, and other outdoor enthusiasts.
The Legal Battle: From Wyoming Fields to Federal Courts
The case that reached the Supreme Court, Iron Bar Holdings, LLC v. Cape et al., originated from an incident in 2021 involving four Missouri hunters on Fred Eshelman’s Elk Mountain Ranch in Carbon County, Wyoming. Eshelman, a wealthy pharmaceutical executive, alleged that the hunters trespassed by using a ladder to cross a corner of his private property to access adjacent Bureau of Land Management (BLM) land. While a local court acquitted the hunters of criminal trespass charges, Eshelman pursued a civil lawsuit, seeking substantial damages and arguing that the hunters’ passage through the airspace above his property constituted a violation of his rights.
Federal courts, including the U.S. District Court for Wyoming, consistently sided with the hunters. The 10th U.S. Circuit Court of Appeals in Denver ultimately issued a unanimous decision in March 2025, upholding the legality of corner-crossing. The appellate court ruled that private landowners cannot use state-law trespass claims to obstruct public access to federal lands via this practice, citing the Unlawful Inclosures Act of 1885. This federal law prohibits landowners from creating barriers that effectively enclose public lands and prevent free passage.
Supreme Court’s Decision Secures Public Access
On October 20, 2025, the Supreme Court announced its decision to deny review of the case. This action leaves the 10th Circuit’s ruling undisturbed, effectively settling the question of corner-crossing legality within that circuit’s jurisdiction. While the Supreme Court provided no explanation for its decision—a standard practice—the outcome is a significant victory for public land access advocates. Approximately 3.5 million acres within the 10th Circuit’s six states are now more reliably accessible, with Wyoming alone benefiting from access to about 2.4 million acres of previously corner-locked public land.
Advocates Hail Victory, Landowners Voice Concerns
Conservation groups and public land enthusiasts celebrated the Supreme Court’s inaction. Devin O’Dea, Western Policy & Conservation Manager for Backcountry Hunters & Anglers (BHA), called the ruling “a resounding victory for all who value their right to access public lands.” He emphasized that “access to 3.5 million acres of public lands has been secured” and that corner crossing is “not a crime.”
However, some landowner groups expressed concern. They argued that the 10th Circuit’s decision, now upheld, could lead to perpetual easements across private properties without compensation and create legal uncertainties regarding liability. Property rights advocates also warned that the ruling could be seen as undermining traditional property rights.
A Landscape of Access Beyond the 10th Circuit
While the Supreme Court’s decision provides clarity for millions of acres in six Western states, corner-crossing remains a legal gray area in other parts of the West, including states like Montana, Idaho, Nevada, California, Arizona, Oregon, and Washington. The 10th Circuit’s ruling serves as persuasive precedent, but it does not set a nationwide legal standard. This means that landowners and recreationists in other states may continue to face legal ambiguity and potential disputes.
The ongoing debate highlights the complex interplay between historical land allocation, private property rights, and the public’s right to access vast natural resources. As special interests continue to navigate land access issues, future legislative or judicial challenges may arise in other jurisdictions. For now, however, the decision represents a substantial win for those seeking to enjoy the millions of acres of public land that define the American West, offering a vital connection to the nation’s natural heritage, and is a significant piece of legal news with lasting impact.
This editorial perspective underscores the critical importance of vigilance in protecting and expanding access to these shared landscapes. The ongoing news cycle regarding public lands access suggests that while this battle has been won, the larger fight for equitable access continues across the vast expanse of the West, and even extending considerations toward coastal public lands access debates, though this particular ruling directly impacts inland areas.
