I'm likely headed back to Shepard Pass/Mt Tyndall/Mt Williamson in the next few weeks (probably the weekend after Labor Day). See the picture gallery for recent conditions. The only sketch part is right before the pass. Others said mid-day it was no problem crossing the snow. It was so steep that we climbed around it.
Lots of bears active (up until ~10500 ft), especially around Anvil Camp. There is bear scat even at the trail head. Also lots of mosquitoes.
Might want to bring slippers for the first 4 water crossings.
I plan to sleep at Horseshoe Meadow for two nights, then above Shepard Pass. I think Mt Williamson needs a full day for me.
