I'm having problems with MTurk. If someone could explain how or where to simply send a coordinate that would be helpful. Examining the kml image from that site I noticed what appears to be a smoke plume. It would seem to be an odd place for a campfire, although there is no noticable debris. Also note how the older GE image does not show this feature.

-edit... looking at these images more closely it looks more like some sort of manmade fire. There is a road intersecting the location and the older image seems to show a very faint bit of smoke along with a circular clearing about the smoke location.
