The following references are the sources used for data regarding this volcano. References are linked directly to our volcano data file. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.

Mount Meager volcanic complex of Pliocene-to-Holocene age forms a dissected andesitic-to-rhyodacitic stratovolcano with multiple eroded summit lava domes and volcanic necks. Mount Meager lies in the Garibaldi volcanic belt and is the northernmost volcano of the Cascade volcanic arc that extends down to northern California. The summit of the complex consists of overlapping piles of andesitic lava flows and younger dacitic lava domes and flows. Quaternary basalts underlying the uppermost 22 km of the Elaho valley originated at the 1375 m level in the South Fork Meager River. The most recent activity from the Meager volcanic complex about 2350 years ago produced Canada's largest known Holocene explosive eruption and an associated welded block-and-ash flow and a lava flow from a vent on the NE flank of Plinth Peak. Two clusters of hot springs occur within the complex, which has been investigated for potential geothermal power.
