Molokini Crater, looking southeastward into the "horseshoe" of the crater.
Molokini Island (area above sea level = 22.4 acres) is the uppermost portion of a cinder cone that erupted within Haleakala‘s Southwest Rift Zone. That part of the cone that emerges above the waterline (49 meters maximum elevation) represents about 30 percent of the rim of a small tuffaceous cinder cone that is approximately 400 m (1300+ feet) in diameter. The crater area of the cinder cone forms a lagoon about 30 m (90 feet) deep; outside the lagoon the bottom drops off sharply to a depth of about 150 m (450 feet). [Photograph of the leeward side of the island taken within the Alalakeiki Channel, to the south of Maui.]
