Three Valley Gap Avalanche Program Prep

Our Columbia Avalanche program team getting ready for winter with a pre-winter arming and placement flight of our Remote Control Avalanche System (RACS) cartridges to their towers.

 

The towers sit high above the Trans Canada Highway, west of Revelstoke (Three Valley Gap).

 

The RACS installation at Three Valley Gap allows remote detonation for avalanche control 24 hours a day vs. traditional fair weather and daylight dependant control. Previously, where high hazard avalanche conditions occurred outside of daylight hours or in poor weather, the highway was forced to be closed until traditional heli-bombing control could safely occur.

 

In addition, the RACS system allows proactive strategic control during low traffic volume windows such as night time or early morning to minimize impact to traffic.

 

RACS results to date (since installation in 2017 & 2018 – ‘3VG Wyssen’ image) have shown significant reduction in total, average and longest closure times in comparison with traditional heli-bombing control methods of similar winter season accumulation levels over the past 15 years in Three Valley Gap.
