No sign of instability on approach or getting into it. 2 good skip cuts no reaction. No reactivity the whole way down. I let my guard down and cut out right right before the LG junction to drop a small rock and popped a slab right above it in a thin loaded rocky zone. Classic spot to pop. Completely my fault. Popped around me. Above, behind and in front of me. Went for a small ride. Not scary but in different circumstances, would be bad.
