Avalanche Summary

Snowpack Summary

The Oct and Nov crusts were very apparent in today's field trip. Both layers were ice and buried about 40cm. This area was likely an anomaly during the warm spell, so expect the crust character to be very different elsewhere. In some areas the crusts have completely faceted out. Wind effect is apparent in any open area with soft windslabs being widespread. The snowpack had a distinct "punchy" or "cakey" feeling to it today. Travel is tedious and difficult up to about 2000m.
