FOUND: one (almost brand-new) Salewa mountaineering boot, sitting on a log at the south end of Spider Meadows. If you can identity the model and size, we'll get it back to you!
Overnighted at the high camp at Spider Glacier - fantastic views overlooking both Spider Meadows and Phelps Basin! We found road and trail conditions pretty much as advertised in Stuke's latest trip report - lots of downed trees and creek crossings, but only one deep enough to merit taking off the boots and wading. No snow worth mentioning until we reached the camp at the base of the Glacier, but there were still plenty of dry sites. The meadow is not yet in bloom (give it a few weeks yet), but still quite beautiful amidst snowy peaks and waterfalls aplenty!
We also scrambled up to the top of Spider Gap to take a look at the other side, but didn't descend all the way to Upper Lyman Lake. Pretty consistent snow above 6000ft, but we managed well enough with microspikes and trekking poles. Campsites around the lake look to be melting out, but we elected to camp on the south side of the gap because weather conditions were considerably more pleasant =)
