Blackcomb Mountain

Blackcomb Mountain

This peak of 2,436 metres in the Fitzsimmons Range of the Coast Mountains is formed of ~150 mya magmatic rock uplifted by movements of the Pacific Plate. The mountaintop remained a nunatak above the last advance of the Cordilleran ice sheet.

The Fitzsimmons Fault forms the valley between Blackcomb and Whistler Mountain, and several prominent gossans (outcrops of oxidized and heavily metamorphosed rocks that can indicate the presence of ore deposits) are visible on Blackcomb Mountain’s lower flanks above Fitzsimmons Creek—best viewed from the spectacular 4.3-kilometre gondola connected to Whistler Mountain as part of the popular Whistler Blackcomb resort.

Hiking trails lead through alpine meadows to various overlooks of the Whistler Valley and Garibaldi Provincial Park, as well as to ice caves on the Horstman and Blackcomb Glaciers, with a loop out to Decker Glacier and its climate-induced meltwater lake.

Cliff areas, loose rock and sensitive alpine ecosystems; stay on marked trails, behind barriers and in designated areas.

Protection and guardianship are at the heart of the Geopark philosophy. We ask that you treat the land with the same reverence as its original inhabitants, and not remove anything from a site but what you’ve brought to help preserve it for future generations.

What Are Pillars?

The Fire & Ice Aspiring Geopark comprises four main geological pillars referenced in all interpretive material: (M)ountain Building, (G)laciation, (V)olcanism and (C)ollapse.


Mountain building can involve several processes that contribute to the formation of mountains, such as the collision of tectonic plates that result in folding, faulting, metamorphism and the creation of subduction zones associated with volcanic activity and igneous intrusion.


Glaciation refers to landform phenomena associated with the formation, movement and recession of glaciers and ice sheets. In temperate latitudes such as British Columbia, montane glaciation at higher altitudes is the norm while continental glaciation occurred during Ice Ages like the recent Pleistocene.


Volcanism is the eruption of subterranean molten rock (magma) and gasses onto the surface of the planet and includes the production of volcanic landforms and the effects of eruptions and flowing lava on pre-existing surface formations.


Collapse is a term that refers broadly to both slow processes of destabilization and erosion by wind, water and ice, as well as rapid processes like rockfall and landslides.

Whether acting as primary or secondary forces, one or more of these processes figure in the creation of each geosite.
