Cape Point is the bend in Hatteras Island where the southerly flowing cold water Labrador Current meets the northerly flowing Gulf Stream. The clashing currents create turbulent waters and a series of shallows known as Diamond Shoals. Warm water, cold water and shoals on the edge of the ocean make for an interesting place.
One of the fisherman said the point was the end of the world. I don't know. Maybe it wasn't the end of the world, but you could see it from there.
