ABSTRACT: The Grassi Lakes located near Canmore, Alberta, are a popular hiking and rock climbing attraction due to scenic trails and cliffs. The proximity of visitors to the cliffs poses a risk of rock fall hazard. While climbers typically accept this risk, managing the risk for public safety within a park facility involves controlling access and implementing feasible rock fall mitigation measures. A summary of the methods used to evaluate potential rock fall initiation mechanisms and site factors contributing to the hazard is presented. A qualitative risk assessment was conducted to assess the frequency and consequences of rock fall and prioritize mitigation options using concepts of tolerable risk for different user groups and regions of the site. The results include targeted scaling, recurring inspections, and administrative controls. These methods offer an effective strategy for assessing and managing risk at geohazard sites where quantitative site data is limited.
