1. Beach Cusps (Blocks 54, 55, and 56) . Beach cusps are a series of low 

 mounds of beach material separated by crescent-shaped troughs spaced at about 

 regular intervals along the beach face (see Fig. 19). If these beach features 

 are found, the spacing between the mounds is paced off and the distance 

 recorded in feet on the form.
