Weather

Calm clear and warm. Light westerly wind for the first half of the day then shifted to moderate NW around 1pm ahead of the cold front.

Snowpack

Colder overnight temperatures Friday night started Saturday colder than the last few days. Snow surface was slow to warm and inhibited new wet avalanche activity.

Avalanche

All of the slides below occurred prior to today. I give them a rough estimate of Wednesday April 8, 2020. They are both wet slabs and loose wet avalanches triggered by strong warming over the last week.
