Cottonwood Canyons Avalanche Information
UDOT uses remote avalanche control systems (RACS) and artillery to trigger avalanches that threaten public roads throughout Utah. Avalanche mitigation cannot take place if people are near targets so UDOT will temporarily close specific backcountry areas and roads, working with local law enforcement.
Follow @UDOTavy on Twitter and Instagram for more information on avalanche mitigation and backcountry closures or visit the UDOT Avalanche Safety website.
Cottonwood Canyons Avalanche Slide Paths: No Parking
From November 1 - May 15 there is NO parking allowed in designated avalanche zones. This applies to both sides of the road within the posted areas.
Please avoid parking in these zones as it inhibits our canyons crews from doing their job safely and effectively and puts your safety at risk.

BACKCOUNTRY USERS
Please respect all UDOT avalanche closures to protect yourself, the public, and future access for backcountry users.
- Check for backcountry closures before heading up the canyons.
- Backcountry closures begin before planned avalanche road closures to ensure complete evacuation, with a typical backcountry closure starting at 10:00 p.m. the night before.
- Overnight road closures typically begin the night before, typically beginning at 12:30 a.m. Avalanche closures may also occur during the daytime as conditions warrant.
- Parking in trailhead areas is restricted daily from 10:00 p.m. to 6:00 a.m. in the winter season for snow removal operations. After large storms, UDOT may close the gates to the Spruces (Big Cottonwood Canyon) and White Pine Trailhead parking areas (Little Cottonwood Canyon) during this time.
