Evaluating the impact of snow fencing on snow conditions and ground temperatures in Hurricane Alley, Dempster Highway, Yukon, Canada
Snow fences were installed at two sites near the Dempster Highway, Yukon, ~ 10 km south of the territorial border, to examine their impact on snow accumulation and ground temperatures. Temperature sensors were installed in August 2018 and snow surveys were conducted throughout winter 2018‒19. Natura...
