Revelstoke

20-40 cm of well-settled recent snow has been wind affected at upper elevations. On North aspects in the alpine, the recent snow sits on dry wintery snow surfaces and possibly surface hoar on wind-sheltered slopes. Elsewhere, it sits on a series of melt-freeze crusts on all aspects below 1900 m and southerly aspects to mountain top. Reports indicate snow is bonding well at these interfaces.

The recent warm weather is expected to have helped old persistent weak layers heal, including a few crusts buried over the last month as well as a facet layer 150 cm deep from the mid-February cold snap.

Wind slabs have shown quite limited reactivity in the last couple of days, a few natural and ski cut size 1-1.5 were observed on Saturday and Sunday. On Friday, most activity in the recent snow was limited to loose dry sluffing.

A couple of recent natural cornice failures size 2.5 did not trigger slabs on slopes below. One entrained loose dry to size 2.

Neighboring Glacier National Park reported a few very large (size 3-4) glide slab releases on Thursday. Glide slabs are hard to predict and can release at any time so it is important to avoid slopes with glide cracks.

Last Tuesday, a natural size 3.5 wet slab was reported from an S-SW aspect at 2500 m to 1800 m along with numerous wet loose avalanches up to size 1. We can expect more activity like this in the heat this week.
