Waterton Lakes

Very cold temps for the next couple days. Prepare with extra layer and warm drinks. Plan to end your day a bit early so as not to get caught out.

Not a lot of field observations on the surface hoar that is now buried at least 30cm. Use caution and careful assessment as windslabs may propagate more dramatically if this layer exists.

A natural cycle was observed from the road today. Several dry loose avalanches up to size 2 and one isolated size 2.5 that ran to valley bottom.

30cm of new snow in the last week with variable winds building soft slab in standard and reverse loaded lees. This overlies the 2022-12-14 surface hoar layer and a settling midpack. Below 1900m the lower snowpack is faceted, however, no failures have been observed. We are tracking two separate unreactive crusts from early season warm-ups.

Thurs
