Active patterned ground and cryoturbation on Muckish mountain, Co. Donegal, Ireland
Abstract Active stony earth circles occur on the less coarse cells of relict sorted nets developed in quartzite debris above 600m ASL on Muckish Mountain, north‐west Ireland. The earth circles are underlain by deformed and truncated podzolic soil horizons that resemble cryoturbations produced by dif...
