The soft surface snow is becoming more cohesive and bonding to the previous surfaces as it settles with mild temperatures. The upper snowpack remains mainly facetted. This is pronounced in shallow areas where there is less than 60cm height of snow. There is inconsistent bridging in the mid-pack over the weak basal facets and depth hoar.

Icefields and Maligne patrols on Tuesday noted no new natural activity. Monday's explosive work South of the Icefields produced soft slabs to size 1.5 on low elevation targets. Also significant surface pinwheels occurred on solar aspects. A size 2 wet slab released below treeline onto the road at Medicine Lake late Monday afternoon.
