Nature
Heart Peaks is a remote shield volcano and mountain massif in northern British Columbia, rising from the Nahlin Plateau in the western Stikine Plateau. Built by repeated eruptions over the past 23 million years, it forms a broad, irregular volcanic mass of basalt, trachybasalt, pyroclastic rocks, and rhyolitic domes, making it the third-largest volcano in the Northern Cordilleran Volcanic Province. Its eruptive history is still poorly understood, but evidence shows both fluid lava flows and explosive, ice-influenced eruptions. The latest known volcanic phase is largely Pleistocene, and a Holocene eruption remains unconfirmed. Its remoteness, uncertain activity, and later mineral exploration add to its significance.
