Abstract
PERENNIAL ice was found late in 1969 near the summit of Mauna Kea, a dormant volcano rising 4,200 m above the sea on the island of Hawaii, 19° 49′ N and 155° 28′ W. A part of the ice-lava mixture lies close to the rocky surfaces near the bases of the south walls of the Goodrich Cone and Summit Cone craters (Fig. 1). Seismic refraction measurements have indicated a minimum horizontal extent of ice of hundreds of metres, and a thickness of many decametres. This ice may be the remains of known Pleistocene glaciation1. It is thought to survive near the surface in present climatic conditions because radiation effects make certain areas of the craters colder.
