Ice Climbers: What's over your head?
Warm temps over the next few days will make thin, early-season ice even weaker.
Watch for isolated slabs, loose dry, and sluffs in consequential terrain.
Riders: If you find the snowpack supportive, you are on a slab over weak facets, it's not a great combo.
Best bet for safe turns, try the ski hill.
No natural activity observed. Keep this on your radar as triggering remains possible with the shallow nature of the overall snowpack. This problem is of most concern in wind loaded alpine features, specifically below ridge tops.
Following a weak weather system from Monday, there was ~10mm of precip. Now, it has been well redistributed in open terrain around the Icefields. The whole area is in rough shape. The alpine is stripped to only the immediate lee features throughout the Icefields and Mt Wilson zones. Deep facet wallowing should be expected on alpine ice approaches. Coming new snow for Friday is only likely to hide surface hazards.
The snowpack is 45-80cm deep and is cold, weak, and facetted. Strong winds have stripped exposed alpine and tree-line terrain, creating hard wind slabs in cross-loaded and lee features. Basal weakness is a combo of large facets and chains of depth hoar.
