ground moraine
Quick Summary
A ground moraine is a deposit of rock debris, known as till, that is laid down beneath a glacier. This material, which can range from clay to boulders, is typically deposited irregularly and forms a blanket-like layer. Ground moraines are the most common type of deposit left by continental glaciers and are usually less than 15 feet thick, though they can reach up to 20 meters. They often create a landscape with low-relief, hummocky topography, featuring small mounds and depressions that can hold swamps or lakes. This type of moraine is a widespread feature in formerly glaciated areas of the Northern Hemisphere.1234

glacial landformDepositional landforms of continental glaciers…large areas, which is called ground moraine. This type of moraine generally has a “hummocky” topography of low relief, with alternating small till mounds and depressions. Swamps or lakes typically occupy the low-lying areas. Flutes (see above) are a common feature found in areas covered by ground moraine.
