That Trittkarren is (german.) these are best described as heel-print karren because they resemble the imprint of a heel. they are nearly connected with subhorizontal, adjacent, flat plains and migrate upslope by cutting 'steps' through the process of retrogressive corrosion. the semicircular form is preserved by the 'horseshoe falls effect' which concentrates the main amount of water on the innermost part of the heel-print. at the upper rim the water gain speed. the thickness of the film of water is indirectly proportional to the speed of the flow. a higher rate of flow results in a greater effectiveness of fresh precipitation added to the flow on the ground, but it also causes the diffusion of atmospheric co2 and more extensive corrosion. most trittkarren originate at the rim of a grike lying below and have moved upward to the surface through retrogressive corrosion. at the base of steep slopes where snow collects, nearly funnelshaped trittkarren appear and are of subnival origin. they are common in the alps [3]. synonym: heel-print karren.?

Quantification of thermo-erosion in pro-glacial areas - examples from Svalbard
Abstract:
Surface changes in recently deglaciated terrain are calculated by comparing air-photo derived digital elevation models (DEMs) from four pro-glacial areas on Svalbard. The paper quantifies the amount of material mobilised due to thermo-karst processes and discusses the influence of the process on the sediment budget of terrestrial arctic glacier basins underlain by permafrost. The study shows that thermo-erosion in deglaciated terrain is an important process which falls within the concept of paraglacial activity. The average annual material mobilisation due to thermo-erosion can be in the same order of magnitude as field-measured total annual suspended sediment transfer out of the catchments. The study implies further that ice-cored moraines are important sediment magazines, which release more material during warmer periods than during colder periods
