CJ Svela-, Nick Hall, Jacob Holcombe; skier triggered avalanche on the East Side cliffs of the Tumalo bowl. Good example of a a perfect 38degree (the sweet spot), lee side w/ lots of new snow and wind loading just below the cliffs, aka, trigger point. First skier initiated the fracture and propagation and second skier initiated the total release of the slab. Crown of the slab was 47cm. Flank-flank was approx 500' wide. Top to noticeable staunchwall was approx 350'. Runnout/path into trees/terrain trap was approx 500'-600' long. We knew the potential for this particular area to slide and demonstrated due diligence in setting off this particular slide path. This was a good exercise to learning how to notice terrain features for initiation or trigger points and recognizing terrain traps.
