The D Trail, part of the Winter Grooming Snowmobile system for over-snow vehicle (OSV)/snowmobile use, is a popular and highly scenic trail that runs east from the OSV staging area at Deadman Summit on Hwy 395 to the warming hut on the 9,046-foot summit of Bald Mountain. Groomed and marked with orange diamonds, the trail goes through old-growth Jeffrey pine forest and wide-open flats popular with snowmobilers looking to play off-piste. The historic warming hut is maintained by volunteers and the US Forest Service, and offers a great place to have a picnic lunch and enjoy sweeping 360-degree views of the entire Long Valley Caldera. 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.
