Just did the South Fork last weekend, 4/13-4/15. The snow starts 1 1/2 miles before Dry Lake. The draw leading to Dry Lake is best approach, if you don’t want to take the switchbacks and climb over 10+ fallen trees on the trail. Dry Lake to summit was fully covered in snow, 2-3′. Snowshoes work fine, but we needed crampons for the summit ridge. The snow was extra stiff throughout the trek. We took the saddle ridge up, traversing rock and snow fields to the left of the major avalanche field. 5 hours from TH to Dry Lake, and 8 hours RT from Dry Lake to Summit.
