The inconspicuous ice-and-debris covered vent of the Bridge River eruption, the last eruption of the Meager volcanic complex, is located near the center of the photo immediately above the forested valley fill. The Bridge River eruption, one of the largest-known Holocene explosive eruptions in Canada, deposited ash to the east across British Columbia into Alberta.
