Ozark National Scenic Riverways

Ozark National Scenic Riverways was the first National Park area to protect a river system.
Civilian Conservation Corps (CCC) would be responsible for reforesting public lands, building roads, trails, bridges, and buildings in state and national parks and other public lands across America during the 1930’s. 
Historic Big Springs has a CCC built lodge and cabins as well as several additional buildings like this.
The Big Spring has a wonderful water color.
The CCC also built an impressive flood control dike that is now part of a hiking trail from the campground.
The CCC workers laid out a trail along the cliff to the back of the spring that blended in with the natural environment. They also built a stone ledge wall in the spring branch to stop animals from entering.
