This road will take you right to the base of "Little Morrison" and save you 2-3 hours on your approach. It is accessed from the Mammoth Cemetary road and runs up to the gully below "Little Morrison". You can only access it in "No Snow" or Dry conditions.
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?
