Object Description


Comments: ATES ZONE SP represents the Avalanche Terrain Exposure Scale (ATES) Zones. 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 polygon layer.
