Kama'oli'i Cinder Cone

Kama'oli'i is one of the many cinder cones that dot the valley floor of Haleakala. Cinder cones are formed as tephra, airborne fragments of volcanic rock, fall to the ground around a volcanic vent. Cinder cones commonly have steep sides with the crater at their summit. Kama'oli'i lies on the southwest rift zone of Haleakala. Rift zones are linear areas of eruptions that extend from the summit of a mountain down the flanks. Haleakala has three rift zones.
