Ice-Rafted Sediments as a Cause of Some Thermokarst Lakes in the Noatak River Delta, Alaska
Irregular, barren polygonal sheets of mud scattered over the landscape of the western portion of the Noatak River Delta are derived from lake-bottom sediments, ice-rafted during flooding. The evidence suggests that the sheets of mud change the albedo and the thermal regime of the soil, induce the de...
