Looking north from the flats below the classic West Bowl of Silver run. May have sympathetic'd out from Doug's Drop natural as well - unknown.

Broke a few inches below the Feb 21 rime crust into 1mm facets in a melt-freeze crust sandwich. At times along the crown line, the facets (think 'stuff' of an Oreo) was 2cm in thickness...other areas it was seemingly the thickness of the facets themselves (1mm). At the crown line, you could feel a mf crust at the bed surface and a mf crust just above at the fracture line. Pic of squares here -
