Snow Profile

General Comments

Looked small compared to the natural in upper Mill B South, Just opposite the ridge of Little Pine to White Pine.

Looked like a hanging slab in lower angle terrain. Would've took some pics but my cameras batteries were dead.

Surface hoar was already forming on Argenta's bed surface.
