Pacific Coast Ranges, Mountain range along Pacific coast in British Columbia, Canada.
The Pacific Coast Ranges form a mountain system along the Pacific shoreline in British Columbia, stretching roughly 1,600 kilometers northward. Dense temperate rainforests blanket the western slopes, while glaciers occupy the higher elevations throughout the system.
Formation of this chain began roughly 200 million years ago when the North American plate drifted westward following the breakup of Pangea. Sedimentary layers accumulated and were later uplifted and folded by tectonic forces over time.
Indigenous groups continue to honor traditional hunting grounds and sacred sites scattered across these slopes. The connections they maintain with the land reflect generations of knowledge and respect for the mountain environment.
The mountains produce strong precipitation patterns and receive heavy rain and snow on western slopes due to air masses arriving from the Gulf of Alaska. Visitors should expect changing weather conditions and limited visibility during cloudy periods, especially in winter months.
Mount Waddington rises within the chain to 4,019 meters (13,186 feet) and stands as the highest summit entirely within the province. Surrounding peaks support some of the largest ice fields at temperate latitudes outside polar regions.
