Object Description


Comments: ATES RECREATION BNDRY SP represents the boundary of the recreation area that has had the Avalanche Terrain Exposure Scale (ATES) completed. The ATES was developed by Parks Canada to help backcountry users assess the severity of the terrain encountered in a given trip. It has three terrain classes that describe the exposure of terrain to potential avalanche hazard. ATES ratings are compiled by professionals who consider eleven weighted terrain parameters in ranking a trip or tour as Simple, Challenging, or Complex. This is a multipart polygon layer.
