🪨 1,000-Year-Old Petroglyphs and CCC Stone Staircases — Missouri’s Ancient Art Meets Depression-Era Craftsmanship — A Missouri state park near De Soto with prehistoric Native American petroglyphs, the famous 1,000 Steps Trail built by the CCC, Thunderbird Lodge, Big River fishing and floating, 50 campsites, 11 cabins, swimming pool, and National Register architecture — Washington County, Missouri
Washington State Park guards Missouri’s largest collection of prehistoric petroglyphs — rock carvings dating back 1,000 years to the Mississippian culture. Thunderbirds, animal tracks, human figures, and geometric symbols are etched into dolomite bluffs above the Big River, one of the Ozarks’ best floating rivers.
Then there’s the 1,000 Steps Trail — a stone staircase hand-laid by CCC Company 1743 (an all-African American crew) in 1936, climbing through forest to a stone overlook with Big River valley views. The park’s CCC stonework is so exceptional it earned a spot on the National Register of Historic Places.
