Johnsons Shut-ins is a 12-foot waterfall on East Fork Black River in Reynolds County, Missouri, in the Ozark Highlands region. It lies about 12.2 miles west of Ironton and roughly 82.8 miles southwest of St. Louis as the crow flies.
At 12 feet it is among the ten tallest of the 8 Missouri waterfalls with a recorded height, ranking 6th. By form it is a cascade, descending over a series of rock steps rather than in a single drop.
The Ozark Highlands are a dissected limestone and dolomite plateau of oak-hickory forest, glades and karst springs. Spring-fed streams and creeks drop over ledges and into sinkholes and caves.
It is the only recorded waterfall in Reynolds County. Mina Sauk Falls, a 132-foot tiered waterfall, is about 5.6 miles away.
