Avalanche Danger Prompts Overnight Interlodge at Utah Ski Resorts

Alta Ski Area and Snowbird Resort enforce safety measures amid heavy snowfall

Published on Feb. 25, 2026

Heavy snowfall in Utah's Little Cottonwood Canyon has prompted the Alta Ski Area and Snowbird Resort to enforce overnight interlodge restrictions due to high avalanche danger. Both resorts have received several feet of snow in recent days, leading to the closure of Highway 210 and the implementation of interlodge, which requires guests to remain indoors while avalanche mitigation work is conducted. The interlodge restrictions have since been lifted, but the avalanche risk remains a concern as more snow is expected in the region.

Why it matters

Avalanche danger is a serious concern in Utah's mountainous regions, especially in areas with high-elevation, avalanche-prone terrain like Little Cottonwood Canyon. The enforcement of interlodge at ski resorts is a critical safety measure to protect guests and staff during periods of extreme weather and heightened avalanche risk.

The details

Alta Ski Area and Snowbird Resort in Little Cottonwood Canyon, Utah, have received several feet of snow over the past few days, prompting both resorts to enforce overnight interlodge restrictions. Interlodge requires guests to remain indoors due to extreme weather conditions or avalanche danger while avalanche mitigation work is being done. Highway 210, which serves the two resorts, has a Utah Department of Transportation Avalanche Hazard Index of 766, the highest in North America, indicating the highway is very dangerous during winter storms.

  • On Wednesday, Alta Ski Area closed at 2:30 p.m. local time due to heavy snowfall.
  • Overnight, UDOT closed State Route 210 and both Alta Ski Area and Snowbird Resort enforced interlodge travel restrictions.
  • The interlodge restrictions were lifted a little before 8:30 a.m. Thursday morning.
