The geometry of this section of the seacoast at Palomarin Beach shows that a large slump block is slowly slipping seaward. The trace of the slump escarpment is defined by the small valley at the right. Also note the synclinal folded beds exposed on the wave-cut bench at sea level. The diagram at right, modified from Cruden and Varnes, 1996, demonstrates the slip and rotation of a block, and the resulting dip of the beds.
