Avalanche Summary
No new avalanches were reported in this region on Tuesday. However, observations are still limited.
Snowpack Summary
Lingering wind slabs may exist in open terrain at treeline and above. The mid-November crust is now buried 80-140 cm deep. There have been reports of small surface hoar forming with spotty distribution. The incoming snow this weekend will be especially reactive where this layer exists. Although reports suggest the overlying snow is well bonded to this crust, this layer may become active as the snow load increases. Below the crust the snowpack is generally well settled. Snowpack depths vary greatly throughout the region with an average of 130-200 cm at treeline elevations. Early season hazards such as stumps, rocks, and open creeks remain the primary hazards below treeline.
