'''Plinth Peak''' is a [[dormant volcano]] in [[British Columbia]], [[Canada]]. It is the youngest vent and the highest of the six named volcanic peaks in the [[Mount Meager|Meager]] [[complex volcano|volcanic complex]] and last erupted about 2350 years ago. Although seen by most as a volcano in its own right, it is technically a secondary volcano of Mount Meager.

'''Plinth Peak''', sometimes called '''Plinth Mountain''', is the highest [[satellite cone]] of the [[Mount Meager massif]], and one of four overlapping volcanic cones which together form a large volcanic complex in the [[Garibaldi Volcanic Belt]] of the [[Canadian Cascade Arc]]. It is one of the most recently formed volcanic formations of the Mount Meager massif.
Plinth Peak is the most recent volcanic peak of Mount Meager to erupt, and the most recent in the [[Garibaldi Volcanic Belt]]. The eruption was similar to the [[1980 eruption of Mount St. Helens]] and sent [[volcanic ash|ash]] as far as southern [[Alberta]] and [[dam]]med the [[Lillooet River]], forming [[Keyhole Falls]]. The steep north face of the peak is the remnant of the inner [[Volcanic crater|crater]] wall, which was destroyed by the eruption.

Plinth Peak is the highest volcanic peak of the Mount Meager massif. Located on the steep north flank of Plinth is the remnant of an inner [[Volcanic crater|crater]] wall that was destroyed by a [[lateral eruption|lateral blast]] during a period of volcanic activity about 2,350&nbsp;years ago.{{citation needed|date=August 2013}}

Plinth Peak, sometimes called Plinth Mountain, is the highest satellite cone of the Mount Meager massif, and one of four overlapping volcanic cones which together form a large volcanic complex in the Garibaldi Volcanic Belt of the Canadian Cascade Arc. It is one of the most recently formed volcanic formations of the Mount Meager massif.

Plinth Peak is the highest volcanic peak of the Mount Meager massif. Located on the steep north flank of Plinth is the remnant of an inner crater wall that was destroyed by a lateral blast during a period of volcanic activity about 2,350 years ago.[citation needed]
