Widespread natural avalanches below treeline on Jake's Peak.

Numerous natural avalanches occurred in the early hours this morning on Jake's Peak. All avalanches were observed in below treeline terrain on NE aspects above 8,000'. All avalanches failed within the storm snow and a density change of F+ hard storm snow on top of F hard snow snow. This layering was easily identified in hand pits at the bottom of the peak and was noted in all inspected areas while ascending. This weak layer was around 15 cm above the old/new snow interface. HN in this area was easily 40 to 60 cm. Above 8,000' where the overlying slabs become slightly stiffer from wind effect, avalanche activity had occurred. Crown lines and debris were covered under 3 to 6 inches of new snow. Most of the avalanches appeared to have failed naturally. A couple may have been skier/snowboarder triggered where debris overran the skin track and were covered by lower end new snow amounts. All avalanche crowns 30 to 45 cm deep were on steep micro terrain features where slope angle was 40 to 44 degrees. Skier triggered cracking was still occurring around noon while breaking trail and while cutting micro terrain slope convexities.
