text: There is a survey marker from the 1840s near here (I think). There are 4 such markers in the vicinity, according to sources on the web. They are small, and I can't make them out using sat images. It would be a nice addition if someone could find these physically, and add them in, since they are of both cartographic and historical significance. There's a cannon to the west of the mark I've made, and a white marble rock to the south. These markers stake out lines for both true north and magnetic north, I think.
