SE Dogtooths... deep slab release?

Seen from Hwy 95, and about 10Km away. Hard to say if there's a really large crown on peak 2660m or if it's shadow from terrain features... the blue line is the potential crown @ ~2350m, ESE aspect. There is definitely fresh debris, new as of late morning/early afternoon Saturday, but not as much debris as you'd expect if it was a really deep slab.... a bit of a mystery!
