A Trail - Groomed Snowmobile Trail 13.9 mi

  • The A Trail, a popular winter artery that runs north from the OSV parking and staging area at Shady Rest to its intersection with Bald Mountain Road at the southern edge of the Mono Basin, is part of the Winter Grooming Snowmobile System for over-snow vehicle (OSV), or snowmobile, use. The route traverses a big part of the largest Jeffrey pine forest in the world. Groomed and marked with orange diamonds and intersection signs, the trail crosses through the OSV tunnel under Hwy 395 just south of the Mammoth Scenic Loop and then skirts along the base of Lookout Mountain. After crossing Owens River Road, the trail climbs more than 1000 feet out of the Owens Basin. The Winter Grooming Snowmobile System is groomed by the U.S. Forest Service with funding provided by the California Department of Parks and Recreation, using monies generated by registration fees and gasoline taxes. Click here for current snowmobile grooming info.

Avalanche Forecast for 03/25/2017

  • With up to a foot+ of new snow in some areas since yesterday and moderate SW winds, small to large wind slabs will be the greatest avalanche concern for today, followed by loose wet snow in the afternoon as skies clear and temperatures rise.  Natural avalanches will be possible, and human triggered avalanches likely.  Careful snow pack evaluation, cautious route-finding and conservative decision-making will be essential Find out More
