Till is a type of unsorted and unstratified glacial sediment that is deposited directly by a glacier as it moves and melts. This material can vary widely in size, from clay to boulders, and serves as a primary indicator of past glacial activity and the processes of glacial erosion. Understanding till is essential for interpreting landforms shaped by glaciers, as it reflects the glacier's movement and the environmental conditions during its advance and retreat.
