Snow surface

Surface is comprised of unconsolidated storm snow (powder). Storm snow gets deeper as you head from south to north (Tin Can has been favored with the Johnson pass side receiving significant less) and increase in elevation.
Did not make it above 2200' today because of poor visibility but we just started to feel and notice wind effected snow at this elevation.


Dug a snowpit at 2200' (see photo): HS=110cm. NW aspect on a 23 degree slope. ECTX x 2. Pre-storm faceted snow is showing signs of rounding (strengthening). Storm snow seems to be bonding fairly well at this elevation.
