The North Slope of Alaska is extensively featured by a characteristic form of morphology designated "thermokarst". Briefly, thermokarst is a term applied to a "karst-like" topography formed in permafrost regions that have had extensive thaw. Aerial photographs of the North Slope reveal many thaw features that have forms analogous to karst areas.
