The What3words site narrows locations down to a 3 meter square, so for example the square at the center of the ring of trees is tiles.drifters.meeting, linked below. The square just south of that is thick.wriggle.founder. It would be interesting if you can zoom in to the specific square on the what3words grid, and that way people can see exactly which tree and spot next to it.
