How are interlocking spurs formed?
From Wiki: Interlocking spurs are a natural geographical feature which occurs in a river’s upper course, where vertical erosion (ending up in giant mounds of dirt and rock) is the dominant force in determining the river’s course. Here’s how they’re formed: 1. In upland areas, small streams begin to develop and erode the landscape. 2. The stream cuts vertically down the landscape. 3. A small v shaped valley is cut. Vertical erosion creates a narrow valler. 4. New slopes are created, 5. The edges of the new hill slopes are called spurs. They line up one after the other. Wiki site below has pictures.
