I’ve done a little practicing and I can now spot Black Rock City on Google Maps when you’re viewing just the map of the entire United States. That’s 4 clicks zoomed in from the widest.
I’ve got to say that it’s made possible by a trick. Google Maps has done increased resolution scans of BRC and the BR Desert so the color of the area stands out as slightly different than the surrounding area. Still, it’s quite a trick to find the one different pixel on a map of the entire US!
