ABSTRACT: An ice avalanche fell from Ghost Glacier on Mount Edith Cavell in Jasper National Park during the night between 9 and 10 August, 2012. It displaced water from a glacier tarn and caused significant damage to park facilities. The timing of the event, outside normal park use hours, ensured no casualties occurred, however, had the event occurred during the day, many park visitors would have been exposed to the outburst flood that washed out a high use hiking trail and buried the picnic area. Parks Canada commissioned a hazard and risk assessment following the event. This paper describes the assessment and discusses the evaluation, selection and implementation of risk mitigation measures. A companion paper in this conference discusses the event and the initial emergency response.
