Little & Big Cottonwood Canyons, American Fork & Provo Canyons Backcountry Closure Information

Backcountry Closure Overview


  • UDOT uses explosives and artillery to trigger avalanches that threaten public roads.
  • Avalanche control cannot take place if people are near targets.
  • Prior to control work specific backcountry areas are temporarily closed under the authority of local law enforcement.
  • Backcountry closures begin before planned road closures to ensure complete evacuation.
  • A typical closure starts at 10 p.m. the night before control work, with estimated re-open listed on the website and twitter feed.

What you can do

  • Respect the closures to protect yourself, the public, and future access for backcountry users.
