This one came out pretty eerie. This is a local park called Brandywine Springs. It was an amusement park up until the late 1920's. This is actually part of an artificial lake built for the park in the late 1890's and drained in the 1940's about a decade or so after the amusement park closed. The lake included a large dance pavilion in the center and paddle boats to ride in. The mounds you see in the water are actually man-made islands which were at one time nicely landscaped. That time has long since passed, though a few fir trees from the time still remain.
