Avalanche radar system installed at Bear Pass, Canada
Our crew successfully completed installing the avalanche radar system at Bear Pass, Canada, for the Ministry of Transportation and Infrastructure (MoTI). Despite challenging weather conditions, the installation team was able to setup and take into operation the four stations to increase winter safety on avalanche-prone Highway 37A in northwest British Columbia. The comprehensive system consists of two autonomous detection stations with an avalanche radar (Little Bears site and George Copper site), a repeater station for data and alarm transmission and a receiver station in the coastal town of Stewart.

The installation crew worked despite continuous rain and snow: This shows mounting of the solar panels and radar on the 6 m high poles at the George Copper site. Four large solar panels and a fuel cell power the system in a sophisticated interaction. The system is designed to run through an entire winter – even under meters of snow. The station communicates with the centre in Stewart via the repeater station at Mt. Johnson.
For this installation, we worked with our local partner, AXIS Mountain Technical.
The George Copper avalanche radar station: Just a few days after installation, the radar already detected the first avalanches on the opposite avalanche slopes.
The second avalanche detection station at Little Bears is setup identically. Solar panels combined with a fuel cell supply the station with electricity for the entire winter. The station communicates with the centre in Stewart via the repeater station at Mt. Johnson.
Mt Johnson repeater station is the highest site and ensures communication between Little Bears and George Copper avalanche radar stations and the Ministry’s office in Stewart.
