Waterton Lakes National Park
Almost any moderately steep slope, under the right conditions, may release its snow load as an avalanche. Even small avalanches can be deadly.
Much of the mountain area within Waterton Lakes National Park is avalanche terrain. In addition, most trails in the park traverse avalanche terrain.
All backcountry travellers are responsible for their own decisions and safety, and should be well informed about the type of terrain they will encounter.
If the terrain you plan on visiting involves some avalanche hazard you will need:
- Training to recognizing avalanche terrain and understand the avalanche hazard.
- Avalanche rescue equipment: avalanche transceiver, probe and shovel combined with the appropriate training concerning their use for companion rescue.
Visitor safety technicians produce a regular Avalanche Bulletin for Waterton Lakes National Park from December 1 to April 15. Avalanche bulletins are posted on Tuesday and Friday throughout the winter season.
Visitors should be aware that periods of avalanche hazard may still exist in Waterton Lakes National Park outside of the regular winter season.
Be aware that there are specific travel restrictions that apply to custodial groups (those which include minors without their legal guardians) between Nov 15 and April 30.
Post wildfire avalanche hazard
Burnt forests can dramatically change the snowpack, creating conditions more in line with what you would usually see in the alpine: increased wind effect and slab formation, and continuous weak layers in the trees. This can lead to larger and more frequent avalanches in paths, and new activity in places where avalanches did not previously occur. Treat burnt forests that are open enough to ski as if they are open slopes, and consider the consequences of being carried by an avalanche through the trees.

Avalanche Terrain Exposure Scale (ATES)
|Simple||1||Exposure to low angle or primarily forested terrain. Some forest openings may involve the run-out zones of infrequent avalanches. Many options to reduce or eliminate exposure. No glacier travel.|
|Challenging||2||Exposure to well defined avalanche paths, starting zones or terrain traps; options exist to reduce or eliminate exposure with careful route finding. Glacier travel is straightforward but crevasse hazards may exist.|
|Complex||3||Exposure to multiple overlapping avalanche paths or large expanses of steep, open terrain; multiple avalanche starting zones and terrain traps below; minimal options to reduce exposure. Complicated glacier travel with extensive crevasse bands or icefalls.|
How much experience do I need for these trips?
Terrain requires common sense, proper equipment, first aid skills, and the discipline to respect avalanche warnings. Simple terrain is usually low avalanche risk, ideal for novices gaining backcountry experience. These trips may not be entirely free from avalanche hazards, and on days when the Backcountry Avalanche Advisory is rated ‘Poor’, you may want to re-think any backcountry travel that has exposure to avalanches – stick to groomed x-country trials or within the boundaries of a ski resort.
Terrain requires skills to recognize and avoid avalanche prone terrain – big slopes exist on these trips. You must also know how to understand the Public Avalanche Bulletin, perform avalanche self rescue, basic first aid, and be confident in your route finding skills. You should take an Avalanche Skills Training Level 1 course (AST 1) prior to travelling in this type of terrain. If you are unsure of your own, or your group’s ability to navigate through avalanche terrain – consider hiring a professional ACMG certified guide.
Terrain demands a strong group with years of critical decision making experience in avalanche terrain. There can be no safe options on these trips, forcing exposure to big slopes. A recommended minimum is that you or someone in your group should have taken an Avalanche Skills Training Level 2 course (AST 2) and have several years of back country experience. Be prepared! Check the Public Avalanche Bulletin regularly, and ensure that everyone in your group is up for the task and aware of the risk. This is serious country – not a place to consider unless you are confident in the skills of your group. If you are uncertain – consider hiring a professional, ACMG certified guide.
