Avalanche Conditions

While out for the weekend in K-country, numerous sz 1-2.5 loose dry and storm slab or wind slab avalanches were either directly observed or results observed on Sunday (dec 8) after the 35+cm of new snow over the past 48hrs gave way to clear skies and cold temps. The ALP or lower elevation terrain that behaves like alpine was particularly reactive from the moment the sun came above the horizon today. Of note, Mt. Murray moraines had a significant sz 2 slab result on a N facing moraine slope below a headwall around 2400m which ran for a few hundred metres (see pic). Also, Mt Chester had a slab result on the S aspect starting near the summit. Black Prince area (Warspite Lake) saw witness to a symphony of loose dry sluffing and sz 1-1.5 loose dry avalanches mid afternoon (sunday) as the temps rose from -20c to -12c and winds picked up in the ALP (significant ridgetop transport clearly visible and backlit from the setting sun). Some parties on an open and exposed slope nearby certainly got front row seats to the show. A few hasty pits below treeline (1850m) revealed a decomposing Nov raincrust 10-15cm above ground in a 50cm snowpack.

Anyone choosing to venture out this week, careful terrain selection will be your best friend. Keep to safer terrain and give those ALP lines and faces some time to bond.

Oh, and watch out for Mortimer the Moose... my truck got a lick'n while pulled over, engine running!
