Large areas of Glacier National Park are CLOSED for avalanche control
using EXPLOSIVES. Daily or annual winter permits are required to access
winter restricted areas. Access information is available at the Rogers
Pass Discovery Centre.
New snow today will likely become moist at treeline and below.
On north aspects in the alpine a 40cm soft slab remains, and has bonded poorly to the underlying facets.
Deep persistent slabs are best managed by:
Cornices are best managed by:
Flurries with an accumulation of 8-15 cm today, accompanied by moderate winds from the SW. Freezing levels are forecast at 1600 m with an alpine high of -4C. The rest of the week looks like a mix of sun and cloud, no more precipitation, and freezing levels around 1800 m.
Temperatures have dipped below 0 at treeline and above for the first time in a week. Expect to find a variable crust in the morning, which may break down into moist snow by the afternoon. Isothermal conditions exist below tree line. Cool dry snow exists on high Northerly aspects.
The natural spring avalanche cycle has continued for over a week now, and produced numerous wet loose avalanches yesterday to sz 3 on primarily north aspects in the alpine and at treeline. Explosives control missions last week produced numerous avalanches on all aspects. A notable recent avalanche was a glide crack release in Mounds path. on Sunday
