Community Surficial Geology and Geohazards Map Series, Fort McPherson, Northwest Territories, Canada

ABSTRACT: Permafrost degradation due to climate warming can impact building foundations, as well as nearby slopes whose stability often depends on permafrost remaining frozen. A set of community maps were compiled with the assistance and support of Ecology North, the Hamlet of Fort McPherson, and the Rat River Development Corporation Ltd. The map series for Fort McPherson, Northwest Territories, included surficial geology; geohazards, including permafrost-related geohazards; vegetation; and results of visual slope retrogression analyses and recommended setback lines. The objectives of the project were to improve community understanding of local conditions, assist land management decisions, and provide baseline references for permafrost and slope stability conditions. These maps comprise one of several proposed adaptation strategies for climate change in Fort McPherson that require geotechnical engineering and permafrost expertise. A poster prepared for community outreach and capacity-building is presented and mitigation options are summarized.
