Started today at about 7:30 from the lambs canyon parking lot. The plan was to ski the ridge line and then low angle terrrain in the Lambs/Mt. Aire area. When we got to the top of the first hill headed to Mt. Aire proper, we decided to skin a little further. As we approached the sub peak of Mt. Aire, with my partner (Skier) in front; I noted a fracture and immediately looked up, where a large crown had formed. Immediately my partner was swept off of his feet, being carried by the large slab. He disappeared into the trees below. Fortunately I was close enough to the ridge line to not get swept in the avalanche. I switched my beacon to search but did not have a close enough signal. I yelled for my partner, he responded letting me know he was not critically injured, but that his left ankle hurt pretty bad. He mentioned he was partially buried, but was able to dig himself out., also that he had hit at least two trees very hard, and that his mount was initially full of snow. were able to ski out slowly and safely.

In hindsight, we got out onto what appeared to be a wind loaded slab, that initially fractured about a foot, then stepped down and propigated, probably to the persistent weak layer. Looking at the size of the slide, we are lucky to be alive. Mistakes were made, and I know I will surely learn from them, hopefully people reading this will too.
