(1) Due to avalanches in place across the highway. (2) This column includes days when restrictions were of a very minor nature, (3) Generally including less than 2 hours of lift operation time. These figures show that in general restrictions other than permanent closed areas are in force only 15 percent of the time including restrictions of a very minor nature. The number of skiing hours lost in the course of a 6months* season due to protective measures is too small to be worth discussion, Since our knowledge of the mechanics of avalanches is incomplete, a degree of hazard cannot be eliminated. Avalanches occur which do not conform to any pattern of conditions or factors yet discovered. But this element of danger is small. Knowing that it exists, the snow ranger can keep it small. In most cases explosives offer a definite solution to the riddle. -6- |
