I just moved to NC and think I found a cellar hole in the woods near my house. Its about five foot deep and maybe 25 by 25 sqaure with a cut path leading out. What's troubling is 1. It doesn't appear to be lined with rocks unless they are covered with leaves, and 2. There is an open well in one corner of the bottom of it. Did they put wells in cellars? I'm baffled as to what it is.
