Jacobs Cavern, Archaeological site in McDonald County, Missouri, United States.
Jacobs Cavern is a limestone cave located east of Pineville near the Arkansas border. It extends roughly 21 meters with walls featuring dripstone formations, while the floor is made of yellow clay mixed with limestone fragments.
Scientific exploration began in 1903 when E.H. Jacobs, Charles Peabody, and Warren K. Moorehead investigated the cave. Their work revealed important information about early settlement in the region, predating the rise of mound-building cultures.
The cave is named after E.H. Jacobs, who explored it in the early 1900s. Local findings suggest the site held deep meaning for ancient people who lived here before the rise of mound-building cultures.
The entrance is easily accessible, and visitors can walk through the cave on a stable floor. Wear comfortable shoes and watch for uneven ground, as the space narrows in places and can be slippery.
Excavations uncovered more than 400 objects, including grinding stones, axes, and hammerstones. This collection of tools reveals that early inhabitants had a specialized culture with advanced craft skills.
