Schematic interpretation of formation of straths through retreat of knickpoints. For a more detailed explanation, contact Paul Bierman at pbierman@zoo.uvm.edu.     Figure 4. Schematic interpretation of formation of straths through retreat of knickpoints. The knickpoints between points A and B, designated n1, n2, and so forth, move upstream with the passage of time, indicated by 1, 2, and so forth, in response to successive drops in sea level (s.l. 1, s.l. 2, and so forth). As a result, the younger and lower straths become entrenched within the older straths.
