In the neighboring Banff, Yoho & Kootenay forecast region, Sunshine Ski Hill reported some small windslabs triggered by explosives in alpine terrain. These were less reactive than yesterday.
Snowpack Summary
Wind effect exists in the high alpine, but many sheltered areas are holding soft snow. The mid-pack is generally strong; however, a facet layer can be found near the ground in shallow snowpack areas. At treeline, average snowpack depth ranges from 110 to 140 cm.
