glacial till

Glacial till is a type of unsorted sediment deposited directly by a glacier as it melts and recedes. It consists of a mixture of materials, including clay, silt, sand, gravel, and larger rocks, all laid down chaotically without sorting by size or shape. This material forms uneven, rugged landscapes such as moraines and cysts. Since till is deposited directly from ice, it retains a diverse mix of particles that provide clues about the glacier's movement and the landscape's geological history. It plays a crucial role in shaping terrains influenced by glacial activity.
