Geology

Heart Peaks is a late-Cenozoic shield volcano, capped by rhyolitic lava domes. The basal shield rises roughly Unit m|900|0 above local topography and is composed of flat-lying basaltic and trachybasaltic lava flows and pyroclastics. The most recent eruption at Heart Peaks is of dominantly Pleistocene age, and late-stage Holocene activity is uncertain. The shield volcano rises above the Heart Peaks Plateau which is sculpted on all sides by tributaries of the Inklin River, which is the east fork of the Taku River. The steep-sided lava domes of the Heart Peaks Formation are formed of porphyritic rhyolitic and minor trachytic rocks and occupy the western side of the plateau.
