Weak layer way down low

Dug an eastern facing pit on the ridge at 9k on the ridge, maybe 10 degree slope, essentially flat. Snow depth was very deep (200cm+) in this location compared to what we have seen elsewhere. We were able to trigger a release 100cm down on the first hit from shoulder height, so CTH 1. We also believe an even lower layer released at the same time, 130cm down. When we slid the slab off, it was very smooth. I don't pretend to be an expert, but it looks like there is still a reactive layer deep in the snowpack.
