Morning light on a group of multi colored cinder cones that sit on the south side of 10,023 ft dormant Haleakala volcano, Maui, Hawaii. Cinder cones are also called pu’u and occur when trapped gas causes fountain-like eruptions during a lava flow. The falling lava cinders stick around the base of an eruption and a pu’u is formed. The most recent eruptions of Haleakala volcano occurred sometime between 1480 and 1600.
