Continually assess your local conditions. Periods of intense sun can quickly destabilize the surface snow.
The base of the snowpack remains very weak. Avoid thin, rocky start zones and shallow areas with variable snowpack depths.
A few skier-triggered storm or wind slab avalanches were triggered on Tuesday. All were relatively thin (10 -20 cm), occurring along exposed ridge features in the western Purcells.
On Sunday a size 3 naturally triggered, deep persistent slab avalanche was reported in the western Purcells (southwest of Panorama). It occurred in large alpine terrain, west facing at 2800 m.
On Friday a size 3 naturally triggered avalanche was reported in the Dogtooth Range. While the failure plane is unknown the report mentions impressive propagation.
Dry, powder snow remains on shaded (northerly) slopes. While moist snow or thin crusts exist on most solar slopes at all elevations.
The mid-snowpack may still contain a number of weak layers, primarily in sheltered treeline terrain. However, no recent avalanche activity has occurred on these layers suggesting the layers are likely no longer a primary concern.
The lower snowpack includes a widespread layer of large, weak facets and or depth hoar crystals. This weak layer continues to be responsible for several very large and destructive avalanches throughout the season.
