Slope Angle
Slope Angle
(Degrees)
Slope angle is one of the most important factors when assessing avalanche probability as it it is the defining feature that allows snow to become pulled down the slope by gravity 76% of all avalanches occur between 34o to 45o with surface avalanches becoming more popular over this degree of steepness 38o is is the perfect angle for creating slab avalanches whilst less less than than 3% of slabs occur on slopes less less than than 30° Avalanche Probability (%)
