Bob, great list. As an ex dirt bag rock climber I can add a few more.
I recommend bringing 4 2" foot square boards for the leveling feet.
West of Bishop
heading out west Line street (168) 8 miles to Buttermilk road
, exit and drive to where you want to park, BLM land and excellent views.
North of Bishop
take the turn for Gorge road
and head left at the T. Drive the paved road for a few miles then after the sharp bend in the road take the next left
. heading up you will find numerous areas to pull off
and they most are pull through or looped for turn around.
Fly Fishermen take notice: this puts you in next to the Owens river Gorge. Awesome year round fly fishing.
south of Lee Vining
off of the north loop of June Lake loop (158) take the Parker Lake road around to the woods located at Map link
. there are plenty of shady spots and you can fish Parker creek when in season.
I just love the west because there are so many BLM and Nat'l Forest opportunities
