Figure 5. Terraces or a hummocky land surface on the slope of a bluff can indicate a former landslide. Terraces can be the surface of downdropped blocks which moved during a slide. Vegetation on the surface of these blocks may be tilted in various directions. The irregular land surface may also occur in a bowl-shaped depression below an arcuate top edge of the bluff, additional evidence of a former landslide.
