Mill D to Soldier to Wilson Clear sky Slab avalanche on NE facing slope near Soldier peak. Elevation 8900', slope angle about 32-38 degrees, approximately 500' wide and running 500'. Slab was 2' deep running on buried hoar layer. Avy was triggered in two parts while walking up the low angle ridge 40' away. We felt a collapse and observed the first 100' wide slab. We continued up the ridge and again remotely triggered the rest of the slope (about 400' wide) while at least 50' away. Felt many collapses throughout the day.
