Colorado River geologic footprint and sandbar formation

NARRATOR: As the Colorado River flows through the state of Utah, we see spectacular evidence of the river's ability to shape the landscape. Running water has cut through ancient layers of rock, producing scenic monuments to erosion. The river's action has also created new landforms. Sandbars have formed as sediment was deposited where the river meanders.

Sandbars consist of many layers of sediment. The layers are not of uniform thickness, for each layer represents a specific interval of deposition.
