Light to moderate winds @ approximately 15-20mph, snow fall was very intermittent
Intentionally skier triggered on a convex area between the rock and cornice on the left side of Tumalo bowl.
First attempt (two ski stomps) to trigger the slide sent a shooting crack approximately 30ft into the bowl, Second attempt (two ski stomps)had the entire slope fail.
Weak layer was approximately 10-14in. down and was roughly 1/3in. deep, crystals looked like buried surface hoar. Test Pit showed two failures of CT 1 Q2 @ 10in.
A second weak layer was also present at approximately 20-24in., also a wind slab but with much less energy
Wind slab seemed to be formed from overnight snow blowing in
