Two relatively small inbounds slides let loose Thursday at Jackson Hole Mountain Resort: one in the Laramie Cliffs area and one near the resort's Expert Chutes.
The Laramie Cliffs area is permanently closed, resort spokesman Eric Seymour said. The Expert Chutes were open, and the slide came from the cliffs above. Seymour said both slides released naturally.
"No skiers or snowboarders were involved," Seymour said in a prepared statement, "and the Jackson Hole Ski Patrol has closed the Aerial Tram, Sublette and Thunder in the interest of skier safety."
The resort plans to start avalanche mitigation work Thursday evening, and anticipates delays opening Friday.
The resort started spinning its lifts late Thursday, around 9:45 a.m. per one skier's account, to mitigate avalanche hazard. There was significant snowfall at Jackson Hole Mountain Resort overnight — 18 inches in the Rendezvous Bowl plot — and the Bridger-Teton Avalanche Center had elevated the risk of avalanche danger to "high" Thursday across all three of its forecast zones.
Avalanches have also been reported in the Snake River canyon, and the Wyoming Department of Transportation is conducting avalanche mitigation work on Teton Pass this afternoon and in the Hoback Canyon this evening.
