* Unsorted and unstratified sediment: Glaciers are powerful forces that can grind up rocks of all sizes and transport them long distances. As the glacier melts, it deposits this sediment in a jumbled, unsorted manner. You might find boulders next to pebbles, sand, and clay all mixed together.
* Angular and scratched rocks: The grinding action of the glacier creates angular, irregular shaped rocks, often with scratches or striations on their surfaces.
* Clay and silt: Fine-grained sediments like clay and silt can also be carried by glaciers and deposited.
* Erratics: These are large boulders that were transported far from their original source by glaciers. They can be very different in composition from the surrounding bedrock.
Examples of glacial deposits:
* Moraines: Ridges of glacial till deposited at the edges or ends of glaciers.
* Drumlins: Elongated hills of till formed by the flow of ice over older glacial deposits.
* Kettles: Depressions in the ground formed by melting blocks of ice left behind by a retreating glacier.
