Widespread whumphing and shooting cracks in previously un-skied terrain. Recent natural activity up to Sz 3 failing on the weak faceted snowpack.
Weather Forecast
Sun and cloud with light flurries the next few days. Temperatures are cooling slightly into the -12 to -16 range. Winds may shift Northerly on Wednesday. No significant snow is expected.
Snowpack Summary
25cm new snow and warm temperatures last week at the Columbia Icefields with 35km/hr SW winds built a windslab at TL and ALP. A rain crust exists below 1900m. The dense upper snowpack overlies a weak faceted lower pack making for unpredictable and dangerous avalanche conditions.
Avalanche Summary
On Friday several size 2-3 avalanches were remote triggered by skiers a significant distance away in the McCarib Pass area. Several avalanches to Sz 3 occurred Saturday along the Parkway with one dusting the highway from Mt. Wilson. Widespread whumphing and shooting cracks were noted in the Whistler creek area on all elevations.
