Title: Monitoring a Shear Frame Stability Index and Skier-Triggered Slab Avalanches Involving Persistent Snowpack Weaknesses: Date: 1994; Authors: Bruce Jamieson, Colin Johnston; Description: Ski guides routinely decide whether to ski or avoid particular avalanche slopes. Similarly, avalanche forecasters for ski areas and highways decide wh...; Object ID: issw-1994-014-021.pdf; Keywords: forecasters, safety decisions, terrain, stability, skier triggering; View additional details about Monitoring a Shear Frame Stability Index and Skier-Triggered Slab Avalanches Involving Persistent Snowpack Weaknesses
