Bridge River Ash, Volcanic ash deposit in British Columbia, Canada
Bridge River Ash is a volcanic ash deposit spread across a large area from southwestern British Columbia to central Alberta. The layer contains fine mineral particles and pumice fragments that stand out distinctly in exposed soil and rock sections.
The deposit formed approximately 2,350 years ago from the Mount Meager Massif eruption, the most recent major volcanic event in Canada. This eruption left ash layers that scientists now use as important time markers in geological records.
Indigenous communities in the region developed knowledge about volcanic events as part of understanding their landscape and environment. This geological history remains woven into local understanding of the land's character.
Access to ash deposits requires geological fieldwork or coordination with research institutions in British Columbia. Visible ash layers are found mainly in rock exposures, excavations, and drill sites across the region.
This ash layer overlaps with other recognized volcanic markers like Mount St. Helens ash and Mazama ash, helping scientists distinguish different time periods. The overlapping of these distinct ash sheets creates a natural archive of western Canada's volcanic history.
