Note the sand accumulation on the beach directly adjoining Fort Macon. With the terminal groin, natural currents are pushed further out from the shoreline, thus bypassing the beach next to the inlet. As a result, adjacent beaches must receive millions of pounds of "beach renourishment" sand (typically, in similar cases, close to every 4 years), which has been shown to impact native wildlife. The terminal groin at Fort Macon reflects the exceptions in North Carolina law that apply to areas of cultural significance.
It is a shame that the state cannot move the fort like thet did the lighthouse
