There was patchy snow on the trail starting at about 8500', in the shaded spots. By 9000' we were hiking on all snow. Fortunately, the snow was well-consolidated and supportable, there was almost no post-holing going on. Above 9500' there was a top layer of 4-6" of mush from last weekend's storm cycle.
We got the opposite of an alpine start; we left Lupine Meadows trailhead at 2:45, but that was p.m. rather than a.m. We met a half-dozen people coming out from the lakes, but saw nobody once we were up there. We ate a quick snack at Surprise Lake,
sat in the sun for a few minutes at Amphitheater Lake,
and then hiked up to the col between Amphitheater Lake and Glacier Gulch. We were hoping for views of the Teton Glacier; it was hidden around the corner so we had to settle for the moraine instead.
Then we headed back down; 3100 vertical feet later we were back at the car by 7:15. A very pleasant late afternoon stroll!
