Ground moraine, also known as glacial till, is a sedimentary deposit created by the action of glaciers. This type of terrain consists of a mixture of rocks, soil, sand, and clay, all mixed together and deposited by melting ice. There are several synonyms for ground moraine, including glacier till, glacial debris, and boulder clay. Other terms used to describe this terrain include glacial drift, glaciofluvial deposits, and rock flour. The composition of ground moraine can vary widely depending on the type of rocks and soil in the area, as well as the size and movement of the glacier that deposited it. Despite its name, ground moraine can be found at various elevations and is not limited to low-lying areas.
