Snowsheds are just one part of Rogers Pass' extensive avalanche program

Snowsheds are just one tool in Canada’s arsenal to combat the impacts avalanches can have on their complex road systems. Snowsheds are aboveground tunnels where snow can travel over it and into the river, thereby reducing the number of road closures to cleanup the aftermath and allowing thousands of drivers to continue on their journeys. This idea is being explored by state officials in Wyoming as a way to improve their avalanche-mitigation tactics.
