The Salton Sea, located in southern California, was created in accident as a result of (mis)-directing the Colorado River some years back, and today is a (huge) land locked sea.

The water has close to 40% more salt than the ocean, yet is a habitat for all kinds of wildlife and transitory birds going north/south. The shores are lined with the skeletal remains of fish, which sounds gross (and in places kind of is), yet it is uniquely beautiful sitting between western mountain ranges. We were camped right along its shores in a state park campground.
