Terrain and Travel Advice

  • Be carefull with sluffing in steep terrain, especially above cliffs and terrain traps.
  • Avoid terrain traps where the consequence of any avalanche could be serious.
  • Avoid lee and cross loaded slopes in the alpine.

Avalanche Summary

A few small persistent slabs up to sz 2 on Southern aspects that ran surprisingly far. Likely triggered by solar radiation.

Snowpack Summary

10-25cm of snow fell earlier in the week with lots of variety on depth based on location! Closer to the divide was less and the east side of the park saw a bit more snow. This new snow fell on a variety of snow surfaces from melt freeze crusts up to 2700m on solar aspects and older windslabs and facetted surfaces on polar aspects. Expect to encounter persistent slabs on lee aspects from winds earlier in the winter. These will be prominent along ridgelines and in gullies. Watch for triggering these slabs from thinner unsupported snowpack areas. Its still very early season out there with a generally low snowpack. Widespread surface hoar is also developing that may become a problem once it gets buried!

Weather Summary

Light winds out of the north will continue over the next few days with cool and clear skies. No new precipitation is expected for the next little while...
