Problems
Persistent Slabs
A 40-50cm soft slab sits over the Dec 3rd surface hoar in many sheltered location between 1500 m and 1850m. Continue to treat all steep (35+ degree) open slopes below tree line with suspicion until you can rule out this weak layer.
- Avoid open slopes and convex rolls at and below treeline where buried surface hoar may be preserved.
- Dig down to find and test weak layers before committing to a line.
