Towering 75 feet above Mission Creek in eastern Wabaunsee County, Echo Cliff was formed from a series of events driven by the movement of seas and streams.
During the Pennsylvanian subperiod, sediments deposited in a shallow sea were later compacted into sedimentary rocks—mainly marine limestone and shale. During a time when the sea receded and the land was above sea level, streams cut channels through the marine rocks and then filled the channels with sandy deposits. The deposits were eventually compacted into freshwater sandstone known informally as the Indian Cave sandstone. A later stream then cut down through that sandstone and other layers to create the cliff.
Privately maintained Echo Cliff Park, marked at the entrance with a unique metal sign, provides easy access to the cliff and creek.
