Yeah, I've seen it. I wouldn't say it had anything to do with jedi, but I've seen what you described. There may be more than one, but the one I remember was NW of the Squill Cave. I would guess it's less than 600m away. If you keep your overhead map active and zoom out as far as possible, you should be able to find it.
BTW, the Squill Cave is around (0,0)
