Giant Concentric Circles in Granite Springs Valley, NV

Here's a google earth view showing the center of the circles mentioned here: https://earth.google.com/web/@40.01244676,-119.000836,1390.6...

Here's another google earth view that shows nuclear test craters by the Nevada National Security Site https://earth.google.com/web/@37.15150881,-116.08582114,1329...

Disturbing and fascinating. I guess I'll have to visit the nearby National Atomic Testing Museum someday. https://earth.google.com/web/@36.1141364,-115.1483791,628.17...

I found this by accident on google earth. It's pretty interesting and weird. I guess that people's best speculation is that it is a remnant from nuclear testing around the 60s.
