 A major process that forms stratified slope deposits in periglacial areas is solifluction of stone blankets in the form of solifluction lobes and sheets.Other processes include rock fall, flow of ice-coasted clasts, flow of dry grains, debris flow and snow avalanches.Other processes that contribute to the formation, but that are of lesser importance, include overland flow of water caused by rain and the combined action of snow and wind.
