Flanking both sides of the Sheyenne River are ridges of sand deposited during recent flooding. These ridges represent natural levees: accumulations of alluvium bordering a stream channel, deposited by the river during times of flood. Over time, vegetational growth on top of the levees tends to stabilize these landforms. In this photo, the land surface gently falls in elevation away from the natural levee toward the wooded background.
