Unique place in the USA: Great Salt Plains Lake, Oklahoma
I tried using Google Street View to find a view of the Great Salt Plains Lake or the salt plains themselves, but it was difficult. The best I could do is below. You can see the white of the salt plains in the distance. News flash: this part of Oklahoma is flat. Click on the map link and then the "Earth" image to see what this place looks like from on high.
This is a unique place; it's a salt lake, a wildlife refuge, and you can "mine" the area for either selenite (gypsum) clusters of blades of selenite that have an hourglass shape visible inside them (like the one shown here).
Happy birthday, USA, and all the great places in this country!
