geschie
Geschie is a term used in glaciology and geology to refer to a rock fragment that has been transported by a glacier and deposited in a location far from its origin. These erratics, as they are also known, can range in size from small pebbles to massive boulders, and their presence in a landscape can provide valuable clues about past glacial activity. Glaciers act as powerful erosional agents, picking up and carrying along vast quantities of rock and debris as they move. When a glacier melts and retreats, the material it has transported is left behind, often in distinct landforms such as moraines.
The composition and type of rock found in a geschie can help geologists determine the source area
