Snow Characteristics

Snow Surface Conditions

Wind Crust

Damp

Snow Characteristics Comments

Snow depths below 8,000 feet are 15-30 cms (6-12 inches) on the shady slopes, with southerly-facing slopes completely bare. I only made it to 8,300 feet, but once you get above 8,000 feet, snow depths are up to 45 cms, especially in wind-loaded areas.

Red Flags

Poor Snowpack Structure

Red Flags Comments

Poor structure, with a 10-15 cm (4-6 inch) layer of damp facets down near the ground. I only made it to 8,300 feet, but I suspect higher elevations have dry facets from November snow down near the ground.

Decreasing Danger

Problem #1 Comments

The snowpack was unreactive where I was looking on northerly aspects just above 8,000 feet, with ECTX (no fracture).

Comments

Travel today was up to 8,300 feet where the dense snow from this past weekend provided supportable travel conditions, although most of the time I was looking upwards to the coverage in upper-elevation starting zones where there is now enough snow on W/N/E aspects that will weaken with the upcoming prolonged high pressure.
