For the final day of the TPF Level 2 class, we stuck to low-angle terrain off Hellroaring Peak and dug a pit below Taylor Creek Road on a 26-degree, western-facing slope at about 6170 ft.
Interestingly, we saw our only propagation in our ECT of the whole course (ECTP30 right above the 1/13 crust). It was at a bit lower of an elevation, so that may have played a role.
But it goes to show that we're dealing with an unpredictable persistent weak layer. When it breaks, it will probably result in large and unsurvivable avalanches.
