Little Cottonwood Canyon (LCC) et la station de ski d\u2019Alta ont une longue histoire de lutte contre les avalanches. La Route 210 de l\u2019\u00c9tat de l\u2019Utah est menac\u00e9e par de nombreux couloirs d\u2019avalanche sur sa route vers Snowbird, la ville et la station de ski d\u2019Alta. De nos jours, avec la popularit\u00e9 croissante du ski, le trafic y est fr\u00e9quent pendant la saison d\u2019hiver. Les experts en avalanches du LCC subissent une forte pression pour garder la route et les pistes de ski ouvertes. Monty Atwater a \u00e9t\u00e9 le premier \u00e0 utiliser des canons anti-avalanches en 1949 aux \u00c9tats-Unis, dans le Little Cottonwood Canyon. Des technologies sp\u00e9cifiques aux avalanches ont d\u00e8s lors \u00e9t\u00e9 d\u00e9velopp\u00e9es dans le monde entier et utilis\u00e9es dans le LCC pour y r\u00e9duire le risque d\u2019avalanche. Le premier m\u00e2t de d\u00e9clenchement d\u2019avalanche Wyssen a \u00e9t\u00e9 install\u00e9 aux \u00c9tats-Unis par le d\u00e9partement des transports de l\u2019Utah (UDOT) sur le c\u00f4t\u00e9 oppos\u00e9 de l\u2019autoroute de la station de ski d\u2019Alta. La station de ski d\u2019Alta, l\u2019UDOT et Snowbird utilisent actuellement des obusiers pour d\u00e9clencher des avalanches. L’arm\u00e9e am\u00e9ricaine Toutefois, en raison de l’obsolescence des canons \u00e0 avalanche, le programme de \u00e9quipement et des munitions, cherche de nouvelles solutions pour le d\u00e9samor\u00e7age des avalanches. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Le domaine skiable Alta a, en 2021, install\u00e9 quatre m\u00e2ts de d\u00e9clenchement d\u2019avalanche Wyssen \u00e0 East Castle pour prot\u00e9ger les pistes de ski dam\u00e9es sous-jacentes. Ceux-ci ont remplac\u00e9 un lanceur d\u2019avalanches qui \u00e9tait auparavant utilis\u00e9 pour att\u00e9nuer les risques d\u2019avalanches sur ce terrain. Le domaine skiable Alta a fait, apr\u00e8s une saison avec le nouveau RACS (syst\u00e8mes de contr\u00f4le des avalanches), ils ont install\u00e9 cinq autres m\u00e2ts de d\u00e9clenchement d\u2019avalanche Wyssen sur le mont Baldy, dans le but de remplacer l\u2019obusier. Les m\u00e2ts de d\u00e9clenchement d\u2019avalanches Wyssen se sont av\u00e9r\u00e9s \u00eatre une solution efficace et efficiente pour remplacer les cibles explosives de projectiles dans le domaine skiable. Ils r\u00e9duisent le temps n\u00e9cessaire au contr\u00f4le des avalanches, ce qui acc\u00e9l\u00e8re l\u2019ouverture des pistes de ski. Gr\u00e2ce \u00e0 l\u2019installation de m\u00e2ts de d\u00e9clenchement d\u2019avalanche Wyssen pour r\u00e9duire le risque d\u2019avalanches dans le domaine skiable, le d\u00e9samor\u00e7age des avalanches peut \u00eatre effectu\u00e9 \u00e0 distance et les collaborateurs de la r\u00e9gion de ski Alta peuvent d\u00e9clencher des avalanches en dehors de la zone dangereuse. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Le domaine skiable de l\u2019Alta et le Snowbird voisin ont \u00e9t\u00e9 les premiers domaines skiables en Am\u00e9rique du Nord \u00e0 installer des m\u00e2ts de d\u00e9clenchement d\u2019avalanche Wyssen. Dave Richards, Directeur de l\u2019Alta Avalanche Office les appelle les \u201etrue Avalanche Hunters\u201c (\u201evrais chasseurs d\u2019avalanches\u201c) du fait de leur efficacit\u00e9. Ce nom a une signification historique, car il fait r\u00e9f\u00e9rence \u00e0 Monty Atwater et \u00e0 son \u00e9quipe qui ont men\u00e9 le premier programme de pr\u00e9vention des avalanches dans le canyon. Wyssen Avalanche Control est fier de poursuivre le travail pionnier de Monty Atwater et The Avalanche Hunters dans le Little Cottonwood Canyon. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
