Another from the dunes I was out at the other day. I went over to check out those little mounds, and it turns out there was an old road there once upon a time. Now its busted up asphalt that nature is reclaiming.
Fun fact, this area has been used to film over 20 movies including the 10 Commandments (1923) and Pirates of the Caribbean (about a mile away at Pt Sal.) I hear you can still find bits of the Egyptian city from 10 commandments buried. Unfortunately, the area the city was built on is roped off most of the year because of the Snowy Plover, an endangered bird.
