Every fall, pronghorn move across the sagebrush east of town in numbers that make longtime residents stop what they are doing and watch. It is not a new habit. Archaeologists working the Eden-Farson site, a few miles from where Highway 191 crosses Highway 28, have documented at least 212 pronghorn processed at a single communal hunting ground, radiocarbon-dated to the centuries just before European contact. It remains the largest known pronghorn bone bed in the region, according to the Wyoming State Historic Preservation Office. The animals crossing this ground today are walking a route their ancestors have used for thousands of years, and so did the people who hunted them.
On June 26, 2026, Governor Mark Gordon stood at Trapper's Point near Pinedale and designated the Sublette Pronghorn Migration Corridor, the first legally protected migration route in Wyoming's history. It spans roughly 150 miles and more than 2 million acres, stretching from the edge of Grand Teton National Park down into the Red Desert. Of the ten segments that Wyoming Game and Fish Department biologists identified as essential to the herd's survival, eight made the final map. Two did not. One of them carries the town's own name: East of Farson.
A Map of the Designated Corridor
The corridor Gordon signed is a milestone by any measure. It gives new project proposals on public and state land inside the route a required check-in with Game and Fish before they proceed, and it restricts surface disturbance entirely within the tightest bottlenecks where the herd funnels through narrow terrain. Wyoming Game and Fish Director Angi Bruce told WyoFile that the ability to migrate is a "key factor" in keeping the herd alive, adding that it matters even more "in severe winters or extreme droughts." She said pronghorn are "long overdue for recognition."
The East of Farson segment is outside the designation. It is the only segment named for a specific town and one of two that were not included in the final designation.
How the Designation Was Developed
The process leading to June's ceremony unfolded through several stages.
- In September 2025, the Wyoming Game and Fish Commission voted to recommend the entire ten-segment route to the governor, overriding its own department's suggestion to trim two sections.
- In December 2025, Gordon reversed that recommendation, excluding roughly 270,000 acres in the Red Desert and East of Farson segments.
- In February 2026, Gordon appointed an eleven-member working group, chaired by Sweetwater County Commissioner Robb Slaughter, to review the science and propose a final recommendation. Gordon told the group directly that the two excluded segments were not up for reconsideration.
- By June 2026, the working group's study supported designating the remaining eight segments and twelve bottleneck areas, with Red Desert and East of Farson still absent.
When asked whether the two segments might be added back in later, the governor's deputy policy advisor, Sara DiRienzo, told County 17: "If you're talking about adding additional segments, that's not part of the working group's charge."
Why This Particular Stretch
The reasoning traces back to land use pressure that predates the June designation. Months before Gordon's final decision, the Bureau of Land Management had already begun scoping a lease sale that put oil and gas parcels directly inside the disputed East of Farson stretch, a proposal reported by High Country News in the fall of 2025. That kind of overlap, between energy development interest and the exact ground biologists wanted protected, is the tension the whole corridor debate has run on since Wyoming first tried to protect these routes back in 2019.
At the June ceremony, Slaughter said, "Today's designation demonstrates that voluntary, locally driven conservation works," as WyoFile reported. The outlet also reported after the ceremony that designation itself carries no guarantee against future stressors on the land.
What the Designation Covers
It helps to be precise about what the designation does and does not touch, because the distinction matters for anyone who spends time on this ground.
- Private land is exempt from corridor protections whether a segment is designated or not. Gordon's policy has never applied to privately held property, inside the protected segments or outside them.
- On public and state land within a designated segment, new development proposals now require review by Game and Fish, and certain activity is restricted in high-use bottleneck areas.
- On public and state land within East of Farson, no such review requirement exists. Proposals there move forward under the same rules that applied before June, the same rules that let the BLM begin scoping oil and gas parcels in the segment last fall.
That boundary has a practical consequence: public and state land on either side of it follows a different review path.
The Herd Doesn't Read Maps
None of the paperwork changes where the animals actually go. The pronghorn crossing east of Farson this fall will follow the same ground their predecessors used long before Wyoming Game and Fish existed, the same ground documented at the Eden-Farson site centuries before anyone drew a corridor boundary at all. What changed in June is not the route. It is which parts of that route now carry a formal check on what gets built beside it.
For a place where the fall crossing is as much a part of the calendar as branding or haying, that distinction is worth understanding, whether you are watching the herd from a truck window on 191 or thinking about what the open ground east of town might mean for how this stretch of Sweetwater County develops over the next decade.
If you are weighing what any of this means for land near Farson, whether you are looking at acreage, thinking about grazing rights, or just trying to understand how state land use decisions touch the ground you already call home, I am always glad to talk it through.
