Avalanche and Its Safety
An avalanche is a sudden and rapid flow of snow, oftn mixed with air and water, down a mountainside. Avalanches are 51 the biggest dangers in the mountains for both life and property.
All avalanches are caused by an over-burden of material, typically snowpack, that is too massive and unstable for the slope 52 supports it. Determining the critical load, the amount of over-burden which is 53 to cause an avalanche, 54 a complex task involving the evaluation of a number of factors.
Terrain slopes flatter than 25 degrees or steeper than 60 degrees typically have a low 55 of avalanche. Snow does not 56 significantly on steep slopes; also, snow does not 57 easily on flat slopes. Human-triggered avalanches have the greatest incidence when the snows angle of rest is 58 35 and 45 degrees; the critical angle, the angle at which the human incidence of avalanches is greatest, is 38 degrees. The rule of thumb is: A slope that is 59 enough to hold snow but steep enough to ski has the potential to generate an avalanche, regardless of the angle. Additionally, avalanche risk increases with 60 ; that is, the more a slope is disturbed by skiers, the more likely it is that an avalanche will occur.
