My friend and I were snowshoeing up to Monogram Lake and Little Devil Peak (turned back 300 ft shy of summit because of suspected wind slab). We went off trail around 4700 ft to cross East, avoiding the large avalanche basin that the summer trail passes through. The Avalanche basin was visible from multiple points on our hike avoiding it, particularly when we got to around 4800 ft and East of the basin. There was a clear large glide avalanche on a south facing aspect on the left side of it. I was at Monogram Lake December 13th 2020, and saw a slab avalanche in the exact same location, along with 5 other avalanches in the basin.Photo:

Did you see shooting cracks?
Yes, IsolatedDid you experience collapsing or whumpfing?
Yes, IsolatedObservations
Along with the glide avalanche witnessed in the basin at 5200 ft, I also experienced isolated signs of wind slab on the ridge just west of Little Devil Peak at approximately 6600 ft . Hard, hollow sounding snow that buckled or collapsed underfoot in a 6 ft wide space. I turned back after experiencing that rather than continue to the summit
