Drove up U.S. 40 to Winters Cutoff, over to 99 W and up to Red Bluff at 4:20 PM. Then turned east on Rt. 36. Began to see snow about 4700 +/- ft. We reached Susanville just after sunset about 6:40. Turned N out of Susanville, up around Hidden Valley. Turned right off the main road just short of the summit on a road that runs to the summit of Antelope Mtn.
