Snowpack Summary
Up to 15cm of new snow has fallen in higher areas and/or areas near the divide. The winds have been light enough to prevent any major wind effect, but immediate lees are likely to have storm slabs from wind transport. Expect these on all easterly aspects in the alpine. This new snow is also adding to the load on the persistent layers. The Feb 11th layer depth varies, but expect to find it anywhere from 30-60cm down. It is a significant crust on solar aspects and a subtle density change on the polar aspects. There are also a number of other crusts present on solar aspects and low elevation non-polar aspects. The Jan 6th layer also varies in depth. In deeper areas it can be down as much as 1.8m, and in shallow areas it can be down as little as 40cm. Below treeline, heat has made for generally crusty conditions. The only exception is in shady areas, where the snowpack is weak still. Snow depths are: Burstall Pass 189cm & Mud Lake 117cm.
