Weak sugary facets formed during a prolonged dry period over a thick melt-freeze crust. In sheltered areas at upper elevations, surface hoar may also be found on the crust. This late January facet-crust layer has demonstrated continuing reactivity in the aftermath of the weekend storm, particularly in the northern half of the region. Travellers have reported remote-triggered avalanche activity and widespread whumpfing on this layer (see this MIN report and this MIN report from Joffre Peak).
