Concerning "the object." I was looking at google EARTH (not map), and after switching back-and-forth many, many times, I located where the object is, and can see a faint white outline that it is there when the google earth image was taken a year ago, 11/15/17.
The wooded area where the object is has two trails visible leading south-south-east from the top of the wooded area. On the righter-most trail, halfway down (south-south-east) there is a small clearing. In the upper-right of the clearing is a faint outline of a white object. It is just above and to the right of a chalky patch on the ground.
The faint object is in the shape of an "A."
All of this just to say I believe the object to have been there for some time.
