Map to Archy sites

It seems that Archy sites aren't too rare, but they are so enveloped in the ground that missing them while searching is common, at least for me. I think that having a map with the general location of the site would be nice. It doesn't have to be like a buried treasure map, though. Pointing out exactly where the site is would be a bit cheap. However, if there was a circle that enveloped a wide area, that would give players a better idea of where to find them. Or, there could be a bunch of little circles, and the player would have to visit every circle on the map to find the site.
