Surface Hoar buried 1 foot deep

We had good visibility and rode to Lulu to look at an ava that was triggered yesterday, a small cornice collapse. The one on Chimney Rock (triggered 2 days ago) was not big, but more indicative of weak layers at the ground. Chimney was 2 slides side-by-side, mid-slope, that likely went at the same time. These likely broke on facets near the ground. The snowpack was thin there. We then rode to Wolverine and Abundance. We saw a new snow slide on Wolverine in the deep cleft on the face. We dug on the shoulder of Abundance (HS 200+) and did not get anything remarkable in our stability test.  We then rode to Henderson Bench. There was one small slide off the Henderson ridge by the radio hut. We dug off the bench and got a surprising ECTP 11 on surface hoar buried 30 cm under. Crystals were not big (2-4mm) and you could not see it in the pit wall, but the ECT sure popped it out.
