Subject: Morning Observations, Natural Avalanches
Aspect: North, North East, West, North West
Fresh natural avalanches within last 24hrs on W-NW-N-NE facing terrain near and above treeline from southerly winds over the last 24-36hrs. Large D2-2.5 persistent slabs were triggered by windloading, and small windslabs stepping down to deeper layers.
Wolverine- N-NE facing, ATL. D2.5 Failing from small windslab, then stepping down and propagating much wider. This avalanche looked to propagate the widest along WNW facing steep rocky terrain where the primarily wind direction would have stripped much of the snowpack hight this season.
W-NW facing Gothic, ATL, D2.5. Failing similarly, propagating widely, failing on variety of weak layers from varied bed surface.
Peeler Basin North Bowl. Another very large natural avalanche. Probably D2.5 . The trouble here, is that there looks to be now cornice fall or windslab to trigger this deep avalanche. It just looks like one deep crown that ran naturally. More information is needed
A second hand report of a large natural avalanche that ran natural today on easterly terrain on Belview Mountain in the Gothic Valley.
Many other natural avalanches were reported above treeline today. These were all generally small, other than the avalanches that previously failed and are noted above.
Weather: Clearing skies, strong north winds above treeline, single-digit temperatures.
