Dozens of small wind slab avys on the way to Rae Glacier

While walking up to Rae Glacier (we were hiking in boots, nowhere near enough snow for skiing), we popped out about a dozen size 0.5 avalanches on a stiff wind slab layer. The propagation was surprisingly far - up to 10m in spots. The slab was surprisingly thick, up to 20cm. We were in no danger because of the simple terrain and lack of snow depth - but this could have easily been more serious in a steeper terrain feature with a terrain trap or above an ice climb. Avalanche season is here!
