Which is "Little Morrison"? Is that between Morrison and Mono Jim? Thanks for the additional info. I remember wondering if there was a way to drive up there when I was passing by it. Also, is the road good enough for all vehicles, or is 4wd needed?
"stay high on the ridge, the creek is a jumble of boulders".
I followed the creek bed up to the first trees (9300 ft.) and found nothing but flat rock and firm footing the whole way. No boulders anywhere. Perhaps the most enjoyable part of the route was here.
