Kame Terraces form along the sides of the glacier rather than at its snout. They are formed by the actions of meltwater streams that flow along the sides of the ice, trapped against it by the valley walls. As the valley walls warm up in summer the warm rock helps to melt the ice nearest to it, forming a long depression or trough along which meltwater flows. Because the deposits in a Kame Terrace have been transported by water, they become sorted, enabling them to be distinguished from lateral moraine deposits which exhibit no sorting.
