Snake River Canyon, the steep-walled gorge south of Jackson that carries U.S. Highway 89 between Jackson Hole and Alpine, was the scene of a rescue operation Sunday evening, June 29, 2026. Traffic through the canyon slowed as the operation played out.
Few details were immediately available. The nature of the incident — whether it involved a vehicle, a boater on the Snake River, or a hiker — hadn’t been confirmed. No agency had released information on how many people were involved or the extent of any injuries.
The canyon is one of the more demanding stretches of road in Teton County. The Snake River runs alongside the highway for much of the route, and the corridor sees heavy recreational use in summer from rafters, kayakers, and anglers. Motorists traveling between Jackson and the Star Valley area were advised to expect delays.
No estimated timeline for the operation’s conclusion had been released as of Sunday night.
