Description :
Turf-banked lobes and terraces on the valley slopes and stone-banked or non-sorted lobes at summits show a distinct regional trend of decreasing size from west to east in the Abisko region. Significant correlations with environmental parameters exist between morphometry and elevation, soil moisture and soil texture. At a regional scale, high soil moisture environments can be associated with larger dimensions. The turf-banked forms in the valleys are associated with deep seasonal snow cover and therefore saturated conditions are believed to enhance gelifluction at these locations. The smaller forms on the vegetation- and snow-free summit sites are believed to be dominated by frost creep.
