Simpson 3 Avalanche Path Berm, Kootenay National Park

Parks Canada is proposing to redesign the existing avalanche static defence structures in the runout zone of Simpson 3 avalanche path to reduce impacts to the Highway 93 South through Kootenay National Park. The project involves the replacement of old earthen mounds with new catchment and stopping berm designed to reduce road closures due to snow avalanches and improve winter road safety. The new stopping berm will be approximately 20m high from catchment bottom to berm crest, and be about 200m in length (perpendicular to the avalanche flow).


This map is for illustrative purposes. The markers represent the approximate locations based on available data. More than one marker may be identified for a given assessment.


Latest update

9 July 2020 – Parks Canada intends to make a determination regarding whether the carrying out of the project is likely to cause significant adverse environmental effects. To help inform this determination, Parks Canada is inviting public comments until 8 August 2020 respecting that determination.
