Keep in mind that even though the hazard is moderate and natural avalanche activity has tapered, human triggered avalanches are still possible.
Recently formed slabs have been slow to bond to the previous surfaces of suncrust, surface hoar and/or facets. These slabs remain a concern and have shown wide propagation.
With recent snow being transported by strong winds, this problem could be amplified in immediate lee and cross-loaded features and take a few days to settle out.
A remotely triggered size 2 persistent slab was reported to Parks staff Monday afternoon, running on the March 31st layer. A few Na avalanches were observed in the park from the extreme winds overnight on Sun.
On Sat, field teams easily triggered sz1 loose wet avalanches below TL with daytime warming. Naturals up to sz3 were seen earlier in the week and were also associated with warming events.
10cm of new snow covers a surface crust on all aspects, except due North where dry snow still exists.
In the upper snowpack, two main layers remain a concern, the Apr 9 crust (down 5-30 BTL) and the Mar 31 crust (down 30-50cm) which both remain reactive to tests.
The mid and lower snowpack are generally strong and the Nov 17 basal weakness can still be found 20-40cm off the ground.
