Round Springs State Park 2005

The spring flows into an almost perfectly circular cavern that has collapsed, and from there it travels through a natural tunnel before it emerges into the spring branch. It is believed that a portion of the spring's recharge area is to the northeast of Spring Valley, which means that the water would have to flow under the Current River to reach the spring. Round Spring was also one of the first parks in the Missouri state park system (1932).
It was a state park from 1932 until 1969 when the people of Missouri donated it, along with Alley and Big Spring State Parks to the National Park Service to become a part of the Ozark National Scenic Riverways. A gift from Missouri to America.
