6 places to explore

This is Osage River country, and most of the river is lake now. Bagnell Dam, built at the end of the 1920s, backed the Osage and its Niangua arm into the Lake of the Ozarks, and upstream Truman Lake fills the valley above Warsaw. South and east the land breaks into spring country, the Niangua below Bennett Spring, the Big Piney at Devils Elbow, the Meramec at Maramec Spring, with I-44 and old Route 66 crossing it through Lebanon, Waynesville and Rolla.

All of it was the homeland of the Osage (Wazhazhe), who hunted and lived in these hills until the Great and Little Osage ceded the land east of a line run south from Fort Osage in the treaty of 1808. Thirty years later Cherokee detachments forced west on the Trail of Tears came through on the road past Waynesville, where Roubidoux Spring was one of their stops.

The region's own subject is karst. Ha Ha Tonka shows what is left when caverns fall in: a natural bridge, a sinkhole called the Colosseum and a spring in a gorge below a burned castle. Ozark Caverns keeps water falling from a solid ceiling. Bennett and Maramec springs each pour out about 100 million gallons a day, enough for trout parks, and at Maramec the water once drove an ironworks.
