The Mount Meager volcanic complex is the northernmost major volcanic center in the Canadian part of the Cascade Range. This Tertiary to Holocene complex has erupted mafic to felsic magmas from at least eight vents. The most recent eruption produced a pyroclastic flow and lava flow from a NE-flank vent about 2,350 years ago. This view from the Lillooet River valley to the west shows, from left to right, the glacially eroded volcanic necks of Mount Capricorn, Meager Mountain, and Plinth Mountain.

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.

The tree trunk next to the geologist was buried by ash deposits from the Bridge River eruption of the Meager volcanic complex about 2,350 years ago, which was then covered by a pyroclastic flow. The deposit has an unwelded base and a darker, more massive welded layer at the top of this photo.

The pyroclastic flow deposit forming the foreground canyon wall on the Lillooet River was erupted from the Bridge River vent on the NE flank of the Meager volcanic complex. A vent to the upper right, below the notch in the skyline, was the source of an explosive eruption about 2,350 years ago. It produced ash that dispersed east across British Columbia and Alberta, the pyroclastic flow mentioned here, and a 3-km-long rhyodacite lava flow.

Mount Capricorn, Meager Mountain, and Plinth Mountain (left to right) are seen above the Lillooet River valley to the SE. They are three of the eight volcanic centers forming the Tertiary to Holocene Meager volcanic complex. Deep glacial erosion has exposed the interior of a group of dissected rhyodacite volcanic remnants that form the highest peaks.
