Observation: Twin Lakes Pass

The snowpack structure is weak—almost entirely so. Today, we were unable to produce any results in an ECT due to the lack of a defined slab. As this low-pressure pattern continues, the snowpack will likely continue to facet on all aspects, further diminishing slab structure. It will be interesting to monitor the southerly aspects to see where a persistent weak layer (PWL) develops within the snowpack on different aspects.

Coverage remains very low, and the primary hazard continues to be hitting rocks and stumps.

A generally weak snowpack NE Aspect - 10,000'.

The primary focus of the day was the snow surface, as we already have a good understanding of whats happening underneath the surface (it's weak...). On north-facing aspects, the snow surface has started to weaken and facet. Outside the wind zone, 3–4mm surface hoar remains preserved in many areas. On solar aspects, the snow surface became damp by midday, and with the ongoing high-pressure trend and warm daytime temperatures, I expect a melt-freeze crust to form each morning this week.
