Explosives control on Saturday produced numerous size 1.5-2 avalanches that ran on the March 26th interface. Some of these avalanches ran sympathetically with other slides, or remotely at distances of up to 300m.

The latest pulse of precipitation brings the storm snow totals to between 75-100cm overlying surfaces that were buried on March 26. This interface consists of a crust which exists on all aspects except true north facing slopes at treeline and in the alpine, where small surface hoar is present in sheltered places . This week's snow continues to be redistributed by consistently moderate to strong variable winds, forming windslabs in unsuspecting locations. Cornices are huge, and will continue to grow with this weather pattern. Below the March 26 interface, last week's storm snow is well settled and bonded, with further strength gains deeper in the pack. In isolated locations the weaknesses from early February linger and the chance for a large, deep release is possible in times of rapid loading from new snowfall, rain or cornice fall.
