Strange looking area to be in the woods. This is either a parking spot for a couple cars or part of a small pond/swamp. This area has obviously been cleared by man or Nature.
Wow! That looks like our "swamp" which has a pond just bug enough for kids to skate. I used to love to tramp out there and watch them skate in the moonlight. One night I went hip deep through the ice, but touched bottom and got out and to the house just fine. Smelled like a muskrat!
