While driving west on Hwy 93 on Sunday morning (July 24) I noticed two
large full depth avalanches on NE aspects in the Vermillion Range that
looked fairly fresh.

One failed on an unnamed peak above the Tumbling Glacier. It looked like a
cornice fall triggered the whole slope beneath. Estimated depth 2 M +,
width several hundred metres (easily seen from 10 km away). This was a
steep planar unsupported slope in the alpine and looked like it failed at
the base of the winter snowpack but not on glacial ice.

The second was a steep couloir near Foster Peak that failed full depth
down to some old grey ice. Estimated thickness 1m+.

The take home is to keep vigilant about avalanche danger and travel only
while the snowpack crusts are intact.
