Avalanche Details

We watched from the uptrack as a skier triggered an avalanche (photo one) on west facing slope above tree line. 3 snowboarders came down just after and triggered the 2nd slide (photos 2,3) as they all went down together directly above the skin track. that one covered a potion of the skin track. Luckily, we had just passed that section and nobody was on it at that moment. Nobody was caught in either slide. The skier triggered avalanche was probably a 10" depth and 20-30 feet wide and 50-60 feet runout, boarder triggered was about 8-10" deep, about 10-15 feet wide at crown and widened as it propagated, runout was ~300ft covering portion of skin track just before the last bit of climb at tree line.
