Mauna Kea (Hawaiian: “White Mountain”), which last erupted about 4,500 years ago, is often snowcapped. Its dome is 30 miles (50 km) across, with numerous cinder cones, and is the site of a major astronomical observatory. Early Hawaiians named the behemoth Maunakea, or “white mountain,” for the snow that caps its broad slopes for parts of the year.
It’s been more than 4,000 years since Maunakea last erupted, but scientists predict it could become active again in the future.
