Greenwater "ghost town" is located in Death Valley, on the same road you take to Dante's View. Except there is a lot more to see at Dante's View. Greenwater has a couple of mine shafts (covered with wire and wooden planks to "protect us") and thats about it.
When we couldnt even find a couple of rusted cans the only assumption we could come up with was that in the heat of the valley the people must have taken absolutely everything with them when they left! That or the elements took care of it for them!
All we found was some cool blue rocks!
We stopped at Dante's View and Mushroom rock while we were in the area too. Cat and her friend Jen are just WIERD!
