Reports from Friday show a natural avalanche cycle during the Friday overnight period as well as explosives control in the Fernie area producing numerous storm slab releases reaching up to size 2. There have been no new reports of avalanche activity since then.
Snowpack Summary
New snow at the end of last week buried a recently formed layer of weak, feathery surface hoar. South and southwest winds have since redistributed the new snow. A mixed layer of melt-freeze crusts and sugary facets sits near the base of the snowpack. The snowpack is deepest in the alpine and at tree line, where you might now expect to find total depths of around 70 cm. These depths taper rapidly at lower elevations.
