Medium

Snow Surface Conditions:

Powder

Rain-Rime Crust

Snow Characteristic Comments:

An inch or two of powder capping a widespread brittle rime crust above around 7500'... Up to 1+cm thick in open areas. More like an eggshell in other areas and much less apparent under trees and in thick forest... In some exposed areas all the fresh snow was blown off the slick and shiny translucent crust....

Red Flags

Collapsing

Red Flag Comments:

I noted a couple instances of somewhat isolated audible collapsing...

Elevation:

High

Trend:

Same

Primary Concern Comments:

We didn't find any very deep wind slabs or see any signs of recent wind slab activity... I think the rime crust kept the snow from drifting much during the windy end-of-year storm, and the fresh snow above the crust is just not heavy enough to cause much of a problem.... I did trigger a couple smallish audible collapses in drifted areas...

The shallow snow cover is just not enough to even come close to covering all the rocks on the east side of Mt. Magog.

Here's a look at the ugly snowpack in the area.... Very weak and very sugary or faceted snow to the ground now capped by a little graupel filled new snow, a brittle translucent rime ice crust , and a little more new snow...
