Up early over Muir pass. The snowfields extended for 4-5 miles and were deteriorating into soft slush mud crap. Less than 1 mph for many hours. We did not like using the snow bridge that other hikers seemed to use and tried to find better routes. One snow bridge we could not avoid but we let some big dudes stomp across it before we tiptoed over it. After Muir hut/pass we made it down to Evolution lake with the intention of making an early camp, but some thunderclouds forced us down to near the Evolution creek ford near McClure meadows. The mosquitoes are getting worse but not terrible… yet.
