Over Snow Vehicle (OSV) Conditions Report

Snowcat Grooming OSV Trails


High Sierra Ranger District


Updated: January 13, 2022

Note: Over Snow Vehicle (OSV) trail grooming has started on the High Sierra Ranger District. 

Current Condition: Most trails have approximately 2 to 3 feet of snow in higher elevations with deeper pockets, while the trails in lower elevations and high sun exposure are melting quickly. On the day of grooming, the snow was frozen solid in the morning but softening quickly.  While most if not all the groomed areas are low avalanche risk terrain, keep avalanche threat in your trip planning, especially those traveling off groomed trails.  The snowpack is most likely consolidating but be on the lookout for unstable areas.  Pinwheels were observed on many steep slopes.  Pinwheels are an indicator that the snow surface is losing strength, which is the precursor to wet loose avalanches which can quickly become very difficult to manage. 

To see a listing of trails that are closed please refer to:  Forest Orders in Alerts and Notices

Trail Considerations:  The Sierra National Forest is working diligently to ensure trails remain groomed on a regular basis, generally grooming is conducted to ensure a good setup overnight when temperatures are still dipping below freezing, and prior to heavier use periods over the weekends.

For more information regarding the snowmobile trails on the Sierra National Forest, please contact the High Sierra Over Snow Vehicle Program at 559-855-5355, ext. 3302

Caution: A concern for members of the public, is to be very cautious using the OSV system. Always be prepared for unexpected and changing condtions.
