Abstract: The primary method for controlling avalanches in Banff National Park is helicopter bombing. In 1970, we began investigating methods of controlling avalanches which would supplement helicopter bombing and provide capability to control avalanches under all winter conditions of the alpine environment. The National Research Council (NRC) and Parks Canada approached the Defense Research Establishment, Suffield (DRES) for advice and guidance. DRES was in the process of developing a radio remote control system and a keen interest was expressed in attempting to apply this system for the control of avalanches. The following specifications were set: 1. The device must be reliable under all winter weather conditions. 2. The explosive charge must be activated remotely by a coded radio signal. 3. The charge must be activated independently of other such devices. 4. The device must be safe to handle and transport. 5. The device must be animal-proof. 6. The non-recoverable cost must not exceed more than $250.00 per explosive charge.
