Avalanche Problems
Our primary concern is a layer of SH that is variable in distribution . This layer was not evident in our snow pit location.
Terrain Use
Our travel plan avoid avalanche terrain over 30° We traveled to observe an avalanche fatality site from 1998. The area had heavily trafficked by snowmobile activity. We remained with our conservative travel plan at 30°
