Planning to do Evolution Valley late July entering and exiting from Muir Ranch (Florence Lake). Looks like on east end it is off trail from North to South Lake or a longer route on a road. I don't really want to smell exhaust while on my trip, so am thinking the following route off trail. But I have limited off trail experience and have not been in the area so no idea if this is a wise choice, I'd hate to be hours into slogging through scree wishing I was on the road! I'm very interested in hearing whether this is advisable.
anticipated off trail route:
From the Piute Pass Trail climb to Grass Lake, follow the Grass Lake Canyon to its end and head south over notch at 10,300’. Stay west of Lake Sabrina, wrapping around the hillside to reach George Lake (10,600’) continue down canyon and climb to notch southeast of George Lake at 11,600’. Work way down south of South Lake to approx 10,200’, attempt to connect to spur trail between Hurd Lake and South Lake, to bring you to Bishop Pass Trail.
