Snow Characteristics Comments
About 10-15 cms new snow below 10,000' on Kessler. Sun and some greenhousing affected the snow surface, but upper elevation northerly aspects should still hold dry snow Wednesday morning. All other aspects - as well as low-elevation northerly aspects - will be crusted.
The few wind drifts from this weekend were unreactive to stability tests.
HS on Patterson's Ridge 1.5 - 2 meters.
Comments
Low danger on north-facing aspects this morning on Kessler. There was a natural cycle overnight, likely during periods of higher precipitation intensity, but the dry, new snow was unreactive on steeper roll-overs this morning. In low-elevation terrain near the base of Cardiff it was very easy to get small push-a-lanches in the damp snow on all aspects.
The new snow had a gentle warm-up today so it has somewhat adjusted to warming from the sun, and would expect additional minor wet-loose activity for Tuesday.
In mid-April, a large avalanche occurred on the Lawnmower, and I was finding a very-shallow snowpack in some areas of the bed surface where there was only 25-50 cms of snow, with facets at the base. Overall the snowpack is stable and for the time being am not concerned about the persist weak layer that plagued us through February. But I am still leery of northerly slopes that avalanched down to the November facets, leaving a thin snowpack in place. The facets I was finding today in these thinner areas on the Lawnmower were dry and weak, and if there is enough of a load of new snow these slopes could become reactive.
