Everything up on The Kern Plateau is groomed. There is a little more then a 11 ft. at the vista, 6 ft. At Blackrock, trail head moved up to Alder Creek.
We were up there on February 23, there was over 11 feet of snow at the pass and at least 8 feet of snow at the top of Sherman Peak. Definitely lots of good coverage up there. Have fun and be safe!
