The geographic feature that forms the border between Arizona and California is the Colorado River. This river flows southwest from the Rocky Mountains and serves as a natural boundary between the two states for much of its length. Additionally, the border is marked by various reservoirs and lakes created by damming the river, such as Lake Mead and Lake Havasu.
