Pu‘u Keonehehe‘e and the two small cones immediately to the northwest (left) are among the youngest cones erupted on the volcano, as recent as about 4,000 years ago. The other cones in this view are part of the Laupahoehoe Volcanics, but much older, dating to 70,000 years ago. The light colored surface between the cones consists of glacial deposits with ages between 40,000
