Figure 23. View toward north of groins near Cape Hatteras 

 Lighthouse; Cape Hatteras Point is about 1 km south of the 

 lighthouse (note the change in shoreline orientation at 

 the groin system. Sand moving from north to south is 

 partially trapped and held north of the groins. The beach 

 to the south (bottom of photograph) consequently receives 

 less sand than it loses, and erosion is accelerated)
