7.21 Avalanche Terrain Exposure Scale

The Avalanche Hour Podcast

In this episode, we explore the Avalanche Terrain Exposure Scale (ATES). We speak to Grant Statham, who developed ATES while working for Parks Canada. Grant discusses its development, creation of ATES ratings maps, and its evolution. Next, we talk to John Sykes, an avalanche forecaster, about his work creating automated ATES maps. Auto ATES significantly reduces the time needed for creating human-generated maps, allowing for further fine-tuning with local knowledge. Lastly, we chat with Andy Sovick about Beacon Guidebooks. Andy and his guidebook authors have incorporated ATES into their products, which aids in backcountry tour planning.
