Avalanche Conditions

Over the past 10 days, we've enjoyed some fantastic conditions in Rogers Pass. Temperatures have ranged from -24 to -4 in the alpine and approximately 50cm of snow have fallen. Winds have typically been from the south-southwest and have been in the moderate range for the past two days. This has created storm slabs in immediate lee features in the alpine and at treeline and some exposed below treeline features. Cornices have grown in size and are looking fresh and sensitive.

This past Saturday was one of the best powder skiing days of the season, with gratuitous face shots and blower powder. While the warming trend has caused settlement in the storm snow, there is still great riding to be found in sheltered areas.

There was a natural avalanche cycle to size 3.5 in many of the frequent performers. We observed one of the Tupper paths send an avalanche and decent sized powder cloud over the one of the snowsheds on the way to the Pass Saturday AM.

Of note today, in Connaught Creek, the STS couloir produced a size 2.5 storm slab avalanche that ran to the terminus of the fan. However the cornices were still intact and had grown significantly. On Sunday Frequent Flyer produced a size 2 that nearly reached the skin track. There was also one size three deep persistent slab on the SE aspect of Grizzly Mountain that occurred during the Northerly winds on January 27/28.

The upper and mid pack are progressively resistant in sheltered areas. However, the November facets are still lurking at the bottom of the snowpack and are not confidence inspiring.
