Quick report

Our goals today were to continue monitoring surfaces and coverage as we persevere through this dry spell. Surfaces remain variable. Coverage is diminishing.

We found good snow quality on a protected north-facing shot, with consistent weak faceted snow near the surface. Of all the surfaces out there, the snow quality in these specific locations remains awesome.

Much of our snowpack on northwest, north, and northeast terrain near and above treeline is composed of facets and crusts to the ground. While we don't currently have a slab, and thus no immediate avalanche hazard, these areas will be interesting when winter returns from vacation.

We found no signs of current instability.

Clear skies and warm temperatures made for another awesome day. Winds were calm to light out of the south and shifted to the northeast this afternoon.

Snowpack

Protected northerly aspects in the Morgan South are holding around 100cm of snow above 10000'. The depth of the snow tapers quickly as you drop in elevation or move around the compass. We hounded in on a location less affected by the wind around 10k on a north-facing aspect and found:

  • The majority of the snowpack consists of large (2 mm+) faceted grains and leftover crusts from 1/1 and 12/24. 
  • In the meaty depth hoar, we found moderate propagation propensity in a propagation saw test. PST51/101 (end) down 70cm (pre 12/24 depth hoar).
  • This structure lacks a slab. ECTX

While travelling today, we also noted a moist surface on an east-facing slope at 11000' around 1 pm.
