The evidence that an area was once covered by a glacier is a U-shaped valley.
Glaciers carve out U-shaped valleys through the process of glacial erosion.
As a glacier moves, it erodes the underlying bedrock, creating a distinct U-shaped cross-section in the valley.
The other options, loess deposits, V-shaped valleys, and alluvial fans, are associated with different geological processes and are not specific indicators of past glacial activity.
