Level Mountain volcano is the most voluminous and most persistent eruptive center of the Stikine volcanic belt in NW British Columbia. The massive volcano covers an area of 1800 sq km SW of Dease Lake and north of Telegraph Creek. An 860 cu km bimodal, Miocene-to-Pliocene stratovolcano with several eruptive centers caps a Miocene basaltic shield volcano. Following extensive glacial dissection and emplacement of late-Pliocene silicic lava domes, lesser activity continued into the Quaternary. More than 20 Tertiary-to-Holocene eruptive centers have been identified in the central portion of Level Mountain and on its flanks. The broad, dissected summit region consists of trachytic and rhyolitic lava domes and was considered to be dotted with several minor basaltic vents of postglacial age (Hamilton and Scafe, 1977), although Edwards and Russell (2000) considered Holocene activity to be uncertain.

The Global Volcanism Program is not aware of any Holocene eruptions from Level Mountain. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Level Mountain page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Meszah Peak Cone 2164 m 58° 29' 0" N 131° 26' 0" W
Meszah Peak of the Level Mountain volcanic complex is viewed from the east. The dark unit in the center foreground is alkali basalt. Trachytic lava flows and agglomerates form a series of benches at the base of Meszah Peak. The cliff escarpments are formed of pantelleritic welded tuffs capped by thin basaltic lava flows. Level Mountain volcano is the most voluminous and most persistent eruptive center of the Stikine volcanic belt in NW British Columbia, covering an area of 1800 sq km north of Telegraph Creek.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. 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.
