This latest storm produced 15 cm of new snow at 6500’, 30 cm of new snow at 8000 feet and 55 cm of new snow at 9000 feet. Some poor bonding with the base layer at 15 cm was observed at 6500 feet while skinning this morning. That layer become much more cohesive as we gained elevation. We did not dig into the snowpack to investigate further.
Rapid warming with our last day of March, as it seemed to feel like the first spring day of the season. Lots of roller balls, and pin wheels observed at peak daytime heating below at and 7000’. On our last run underneath Highway two at about 6400 feet on a westerly aspect. I triggered a wet loose slide that was congruent to poorly bonded interface we observed in the morning from the new snow that fell from day before.
Further day time heating will likely trigger wet loose slides on exposed aspects at lower elevations.
Above 8000’ the snow was still wintery and dry in shaded northern aspects.
