Alberta is a province known for its prairies, mountains, and boreal forests, is not typically associated with volcanic activity.
However, the geological history of the region tells a different story.
Let’s explore the presence or absence of volcanoes in Alberta, as well as the province’s relationship with volcanic activity.
Are There Volcanoes in Alberta?
No, Alberta does not have any volcanoes.
However, the province has been impacted by volcanic eruptions from neighbouring regions, particularly from the west coast and British Columbia.
Sources of Volcanic Ash Deposits in Alberta
Mount St. Helens
In 1980, the eruption of Mount St. Helens in Washington State had a far-reaching impact, including in Alberta.
Ash from the eruption accumulated in southern Alberta, affecting visibility and causing issues for vehicles and individuals with respiratory illnesses.
Glacier Peak
Around 13,500 years ago, a massive eruption from Glacier Peak deposited a distinct ash bed in the southern part of Alberta.
This ash bed has been preserved in the geological record and is significant for geologists and archaeologists.
Mount Meager
Ash from Mount Meager, one of the northern-most Cascade volcanoes near Pemberton, BC, can also be found in Alberta.
Known as the Bridge River Ash, it is approximately 2,500 years old and can be found along river banks from Calgary to Hinton.
Mount Mazama
The eruption of Mount Mazama 7,600 years ago was one of the largest eruptions in Earth’s history.
Ash from this eruption can be found all over southern and central Alberta, up to 15 cm thick in some locations.
Alberta’s Proximity to the “Ring of Fire”
Western Canada, including British Columbia, lies along the Pacific “Ring of Fire,” an area with active volcanoes.
While Alberta is not directly on this ring, it is close enough to be affected by eruptions in British Columbia.
In Summary
- Alberta does not have any volcanoes.
- The province has been impacted by ash deposits from various volcanic eruptions, including those from Mount St. Helens, Glacier Peak, and Mount Mazama.
- Alberta is geographically close to the Pacific “Ring of Fire,” making it susceptible to the effects of eruptions in neighboring regions.
