Turf-banked terraces in Öraefi,southeast Iceland: Morphometry, rates of movement, and environmental controls

Small-scale turf-banked terraces are widely developed on low- angled slopes above the Neoglacial trimlines of the Oraefi outlet glaciers in southeast Iceland. These features, which have not been previously described in this area, comprise a vegetated riser and a vegetation-free tread. The morphometr...
