- Summary:
- Permafrost was discovered in 1969 at an altitude of 4,140 m near the surface of Summit Cone crater on Mauna Kea, Hawaii. Although the mean annual air temperature of the area is well above freezing, the permafrost is at least 10 m thick. The local trapping of radiationally cooled air, a low angle of incidence of sunlight, and a very dry atmosphere are associated with its survival. The permafrost does not appear to be in thermal equilibrium with the present microclimate of the crater.
