    There has been very little new snow since the end of November (15cm). This drought interface, down 10cm, is the layer of concern. Remain vigilant by avoiding small pockets of windslab particularly at upper elevation ridge tops.

Weather Forecast

A ridge of high pressure and cold arctic air will be here tomorrow. Friday will be sunny, no precipitation, a high of -18C and a low of -20C, generally light Northerly winds. Saturday will be much the same as Friday except for some gusting Northerly winds at ridgetops.

Snowpack Summary

In the alpine the snowpack surface has been tortured into a contortion of sastrugi making for ugly skiing. Recent moderate SW winds have formed isolated pockets of windslab in exposed areas at upper elevations. Below is an old snow interface of facets, crust and surface hoar. Several other noticeable crusts lie dormant deeper in the pack.

Avalanche Summary

No new avalanches reported or observed.
