Although the basal weakness (depth hoar) is generally dormant, with no recent natural loading of the snowpack, these may still be possible in isolated places. Steep, unsupported, and thin depth are factors to be wary of, as are cornices overhead.

Snowpack Summary
Towards the Icefields, the alpine is wind affected. The Jan 18 surface hoar layer (down 40cm) has faceted away in most places, but shows isolated sensitivity at treeline and below in the Ice fields region. The midpack is mainly supportive, over depth hoar in shallow areas. Although structurally weak, this layer has been generally dormant lately.
Avalanche Summary
No avalanches were observed in the Eastern part of the park today. The snow pack continues to facet with cold temperatures.
