Good move National Park Service, protecting the Little River of Lookout Mountain. They actually partnered with NASA …strange.  It’s a real life application of the “spaceship earth” concept; what we have here on this earth is all there is, preserve and conserve.  They fly a very cool “blue marble earth” flag.   The Preserve is a long narrow park that protects a beautiful 600 foot deep, shear cliff walled canyon and the river that has carved it.  Trails and a drive give pretty good access.  It is neighbored by DesotoState Park. This is a great corner of Alabama.
