Avoid wind-affected slopes steeper than 35 degrees. “Keep it simple and avoid avalanche terrain.” We skied upper and lower Marshall Bowl back down to Marshall Lake, keeping it close to 30 degree terrain, avoiding trigger points and terrain traps.
We were gaining the ridge on the SE aspect above Upper Marshall lake and felt anxious about entering more wind affected, exposed slopes. Decided to dig a pit before entering greater than 30 degree terrain.
Observed Avalanche Problem #1:
Upper Marshall Lake Bowl
Elevation = 9,580 ft
Time = 12:52pm
Slope = SE Aspect, Approx. 31 Degrees
Sugar Layer at 145cm Above Ground
Total Ht of Snow = 240cm
2 wrist taps broke to 215cm (CT 2)
3 additional wrist taps broke to 145cm sugar layer (CT 5, 145cm)
Potential Size = R3
