Talk about misleading. I present one example.

In the episode Lost City of the Kalihari, they show Google Earth shots and probably, purposefully show the wrong coordinates. Here are the correct ones you can put in Google Earth and you can see those rings (yes it's a minus sign, it has to be in there, -30.013446,21.103996 . What I say is that Jamie Visser could have done 5 minutes worth of more research if he's using Earth as his tool. If you use the Historical under View, you will see some odd things happening. When I used Sun under View, I narrowed it down to the rings absent 8/8/2011 at 4:47pm and completely appearing at 5:11 pm. Taking less than 1/2 hour to create all those shapes. Which any person could have easily researched. As it turns out, it's a farmer trying to save water for the dry season.
