Figure 3 A schematic diagram showing how various topographic forms, including rock glaciers, could be produced by varying amounts of ice and weathered rock debris onto a glacier surface. Although not discussed here, the other features named relate to the relative proportions of ice and debris. Thus, if a glacier is active and the debris input is not high, then moraines can form but if the debris input is high and ice activity (volume per year or flux) declines then a rock glacier may form. From (Whalley, 2009).
