I've never been to Angels Rest in winter. Wanted to get to the top at sunrise. My timing was pretty close, maybe about 15 mins early.
Disappointments at TH: Crowded, damp (drizzly). I figured it would dry out up high, turn to snow. It did. Never much though, just intermittent flurries. Cloudy, poor views. Still, nice scenery. Dead calm. Easy to follow trail, little snow and no ice. No more than 6" (didn't measure, just guessing). As expected, snow turned back to drizzle on the way down.
