Issued: November 01, 2019
Prohibition of travel by any custodial group* in avalanche terrain described by the Avalanche Terrain Exposure Scale (ATES) as class 2 and 3.
Effective date: Nov 15 to April 30
Pursuant to section 7(1) of the national parks general regulations, travel by any custodial group* in avalanche terrain described by the Avalanche Terrain Exposure Scale (ATES) as class 2 and 3 is hereby restricted by order of the superintendent, Jasper National Park.
* A“custodial group” means a group affiliated with an institution, where at least one person is below the age of majority and that minor is not in the company of his/her parent or legal guardian. Institutions include but are not limited to schools, Scouts/Guides, churches, clubs, cadets, and community youth programs.
- Subject to the following restrictions, authorization for a custodial group to travel in ATES class 2 avalanche terrain may be granted by the Superintendent:
- The custodial group must be led by a mountain, alpine or ski guide certified by the Association of Canadian Mountain Guides or International Federation of Mountain Guide Associations.
- Maximum group size is nine (9) persons plus certified guide(s).
- Authorization for travel by a custodial group in class 2 terrain will only apply when the certified guide has rated the slope specific snow stability of that area to be ‘GOOD’ or ‘VERY GOOD’.
|1||Simple||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.|
|2||Challenging||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.|
|3||Complex||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.|
