My main focus in this pit was the touchy buried surface hoar layer around 48 cm. I wasn't sure if it would have survived the time leading up to this storm. Our whole class (4 separate pits in a 50' by 50' area) found reaction on this layer from the wrist. However there was little propagation with our ect's. I imagine the overlying slab has yet to gain cohesion; very low density. However another group a couple hundred yards away had propagation from the wrist at this same layer. Below is a picture of the surface hoar in the pit, then one I took a few days prior to it's burial and the third photo is the surface hoar layer with my crystal card offering slightly better visualization, inserted behind a thin slice vertically.
Below this is a photo of some of the larger surface hoar I found by the creek. The largest I spotted I estimated to be the size of a quarter which is apparently 24.26 mm across. Many were dime sized (17.91), and all the way down to measly 5 mm. However these seem to exist in more unique sheltered, isolated locations. But a larger concern of mine is the spotty sneaky mid elevation smaller grained surface hoar. Below that is a 15+ ish foot crack that shot out from Liam's feet early in the morning.
