What kind of terrain and landforms would indicate the prior existence a valley glacier?

The presence of U-shaped valleys, which are often wider and deeper than river valleys, indicates the former existence of a valley glacier. Other landforms such as moraines, which are accumulations of debris deposited by the glacier, and cirques, which are bowl-shaped depressions at the glacier's head, also suggest glacial activity. Additionally, features like fjords or hanging valleys can provide evidence of glacial erosion. Scratched and polished bedrock surfaces, known as glacial striations, further indicate the movement of a glacier across the terrain.
