Weak faceted grains have formed above and below a widespread crust that is buried by 50 to 100 cm.
Verify the forecast with your local conditions. As snow accumulates on Wednesday, both natural and human-triggered avalanches may become likely.
Weak faceted grains have formed above and below a widespread crust that is buried by 50 to 100 cm.
Snow continues to accumulate atop various potential weak layers and good sliding surfaces. Expect slab size and reactivity to increase in wind-loaded terrain features.
Numerous natural and explosive-triggered avalanches, up to size 2, failing on the buried crust/facet combination occurred throughout the region on Monday.
A fatal avalanche incident occurred on Saturday near Gardiner Creek. It is believed that the same layer of facets on a crust was the failure layer. You can read more details here.
Roughly 30 to 50 cm of recent snowfall has buried a variety of potential weak layers, including sun crusts on south-facing slopes and faceted snow or surface hoar in north-facing terrain.
A widespread crust formed in early February is buried by 50 to 100 cm. In some areas, weak faceted grains have formed above and/or below the crust.
The remaining snowpack is generally well-settled, with no current concerns.
