Heart Peaks VulkanHeart Peaks shield volcano is located NW of Level Mountain in NW British Columbia, Canada. It is the third largest center in the northern Cordilleran volcanic province. The volcano, covering an area of 275 sq km, last erupted during the last ice ages, and it is uncertain whether there are any younger eruptions in the past 10,000 years.
Beschreibung:Heart Peaks shield volcano has a basal shield capped by rhyolitic lava domes. The shield is composed of flat basaltic and trachybasaltic lava flows and some tephra layers.
The shield volcano rises roughly 900 m above the Heart Peaks Plateau, which is sculpted on all sides by tributaries of the Inklin River. The colorful bright green and pink, steep-sided lava domes of the Heart Peaks Formation are porphyritic rhyolite and minor trachytic rocks and occupy the western side of the plateau.
