Route & General Observations
A snowboarder rode the slope 3 times and a sledder high marked it before the slope broke from a sledder hitting a drop and triggering the slide.
|Trigger||Snowmachiner||Avalanche Type||Hard Slab||Aspect||North Northeast|
|Elevation||unknown||Slope Angle||38deg||Crown Depth||3ft|
Snowmachiner Aired, upon landing he triggered the top slab to break. Then that stepped down and it broke down to the ground. Moderate amount of energy.
Obvious signs of instability
|Recent Avalanches?||Yes||Collapsing (Whumphing)?||No||Cracking (Shooting cracks)?||No|
Point realeases on sun exposed aspects.
