During the study measurements were taken to determine the thickness of the thawed layer of the palsa during the thaw period in 1974. The air temperature on the surface of the palsa was recorded continuously throughout the study. Melting was at its strongest in June-July and on the southern slope of the palsa. Those parts of the palsa where cracks had formed in the peat melted at the same rate as parts free of cracks. A rise in the surface of the frost layer occurs sporadically.
