I originally wanted to do the whole thing on foot, so I parked at a gaging station on Independence Creek. The plan was to walk from there to the Baxter Pass Trailhead and walk back to there from the Shepherd Pass Trailhead. The walk through Owens Valley to Baxter Pass Trailhead was lovely, but since I bailed at Kearsarge before making it to Shepherd, I got a hitch from Onion Valley down back to my car.
The weather was perfect, blue skies, no smoke, 60s during the day and 40s at night. There were no mosquitoes anywhere except Lake 11407 in Gardiner Basin (where there were millions!).
The Caltopo map of the route is here.
A full report is here:
Day 1: Independence Creek to Oak Creek
Day 2: Baxter Pass
Day 3: Sixty Lakes Col
Day 4: Gardiner Pass
And here are some highlights.

Campsite near Oak Creek

Lower Baxter Pass Trail - well-enough maintained until the second crossing of Oak Creek

Upper Baxter Pass Trail - an almost nonexistent cut through the chaparral in some places and I wish I had worn pants to protect my legs from white thorn and willows

Below 10,000 feet was hot, buggy, and weeds over my head. Fun!
