Ultras of Canada: Mountains with 1,500 m or Greater Topographic Prominence

Definition and measurement

Topographic prominence is the vertical distance between a summit and the lowest contour line encircling it and no higher summit; that lowest point is the key col. Measuring prominence requires reliable elevation data, topographic maps and, increasingly, digital elevation models. For a technical introduction see topographic prominence, and for general mountain terminology consult broader mountain resources at mountain definitions and guides.

Geographic distribution

Canada's Ultras are concentrated in the western Cordillera — British Columbia and Yukon are particularly rich in high-prominence peaks — with additional examples in the far north and along coastal ranges. Eastern Canada has far fewer Ultras; the Torngat Mountains and some Arctic ranges include isolated high-prominence summits. The pattern reflects tectonics, glacial carving and the depth of intervening cols that separate peaks.

Notable examples

• Mount Logan — Canada's highest peak and a dominant Ultra that rises far above surrounding terrain
• Mount Saint Elias — a massive coastal peak shared by the Alaska–Yukon region
• Mount Fairweather — notable for its coastal prominence and severe weather
• Mount Waddington — the highest mountain entirely within British Columbia
• Mount Robson — the highest peak of the Canadian Rockies and visually prominent

Uses and significance

Lists of Ultras are used by geographers, climbers, conservationists and land managers. For mountaineers, tracking Ultras is a peak-bagging objective that highlights isolated, dramatic summits. For scientists and planners, prominence informs watershed boundaries, landscape character studies and mapping priorities. Because data sources and elevation models improve over time, published counts and prominence values may be revised; consult current catalogues for the latest figures.

Finding the complete list and resources

Comprehensive sortable catalogues and interactive maps collect the 143 Canadian Ultras for reference. For a full tabulation and sortable presentation consult the dedicated compilation at the Canadian Ultras list. For global context and how Ultras are defined internationally see what constitutes an Ultra. Additional regional guides, climbing reports and mapping tools are available through mountain resource sites and topographic services (see mountain resources).
