Shallow snowpack and the advanced depth hoar on the ground was concerning looking, but the moist 4F+ depth hoar was apearing to provide some stability.

Persistent Weak Layer
Problem #1 Comments

Looking at the snow structure with the advanced striated crystals on the ground it was a concern, but due to them being moist it appeared to prevent the pack from failing on that layer.

Comments

Looking at the snow structure with the advanced striated crystals on the ground it was a concern, but due to them being moist it appeared to prevent the pack from failing on that layer. There is a fairly stout crust existing above the depth hoar along with the decomposing rime crust and the shallow snow pack causing much of the pack to facet out. Other than the top foot of snow the rest seems to be moving away from rounding, towards a shallow faceted snow pack.

Moist semi chained up 2-3mm striated hollow cups.

Could pack the depth hoar into a snowball, good sign they are wet. They also were denser/higher resistance than they looked.
