The C Trail, part of the Winter Grooming Snowmobile System for over-snow vehicle (OSV), or snowmobile, use, is a popular and very scenic winter artery that runs north from the OSV staging area on upper Hwy 203 (at the Southern California Edison plant between the Mammoth Scenic Loop and Main Lodge) to Deadman Creek and an intersection with the G Trail. Groomed and marked with orange diamonds and trail intersections, the trail winds through old-growth Jeffrey pine forest and the wide-open meadows of Crater Flat along the edge of the Owens River Headwaters Wilderness. At the base of White Wing Mountain, head east along the Deadman Creek drainage to the G Trail. Return the way you came or make a loop. 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.
