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.

Caution: A concern for members of the public, is to be very cautious using the OSV system. The fluctuating weather and temperatures has melted out the snow on the trails, and has severely hardened the snow, or turned it to ice in many areas. Always be prepared for unexpected and changing condtions.
