The term "shut-ins" is an Ozark noun used to describe the geological formation caused when a river's path cuts through large-scale bedrock. The rock, meanwhile, splits the river into multiple stream-beds, surrenders itself to erosion, and forms hoodoo-like spires, potholes, slides, plunge pools, etc. As Pulcheria described it: "it's kind of like Goblin Valley, but with running water." Johnson's Shut-Ins State Park is one of Missouri's finest locales. We camped there a couple days ago, after the Labor Day crowds had abated, and had a fantastic time. Anyone wishing to book a trip with us may contact Pulcheria. We'll love to share it.
