Winter is back! ❄️ Rugged travel down low could be rewarded with good riding up high.
Evaluate how new snow is bonding to the crust and avoid areas where it feels stiff or slabby.
Watch for reactivity in wind-affected features. Although storm totals are small, slabs may slide easily on the crust below.
The likelihood of avalanches on buried weak layers is decreasing, but we are uncertain how quickly. High-consequence slopes should be approached with caution.
We expect avalanche activity to increase on Sunday with cooler temperatures and fresh snowfall. As you gain elevation, evaluate how new snow is bonding to the crust and look for signs of instability.
Up to 30 cm of new snow overlies a crust at most elevations. Below 1000 m surface snow may remain moist or wet.
A layer of facets (and small surface hoar in some areas) is buried 30-60 cm deep and a layer of facets on a crust is buried 80-100 cm deep. While cooler temperatures have allowed these layers to strengthen we continue to monitor them for signs of reactivity.
The snowpack depth at treeline is roughly 100 to 150 cm
