Heart Peaks is a late-Cenozoic shield volcano, located 91 km (57 mi) northwest of Telegraph Creek and 33 km (21 mi) northwest of the Level Mountain Range, British Columbia, Canada. It is capped by rhyolitic lava domes. It is part of the Pacific Ring of Fire that includes over 160 active volcanoes. The basal shield rises roughly 900 meters 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. 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.
