- Summary:
- Mauna Kea is the highest of five massive shield volcanoes that forms the island of Hawaii. Standing at an altitude of 13,796 feet, it is estimated that this volcano last erupted approximately 4500 years ago. This elliptical caldera is inferred to lie buried beneath hawaiite lava flows and pyroclastic cones that are located at approximately the 12,631 foot elevation. Stratigraphic relationships indicate that hawaiite eruptions began before a pre-Wisconsin period of ice-cap glaciation. Indications also infer that the crest of the mountain attained its present altitude and gross form during a glaciation of probable Early Wisconsin age.
