Old Davidsonville State Park [AR]
Established in 1815 on the banks of the Black River, this important frontier town had Arkansas Territory's first post office, courthouse, and land office. When bypassed by the Southwest Trail from St. Louis to Mexico, the town began to fade, and was virtually unoccupied by the 1830s. Because there has since been little disturbance, archaeologists have recently uncovered the town three inches below ground. Finds include corners of buildings, streets, and a volume of artifacts, which are currently at the University of Arkansas being catalogued and preserved.
The site offers exhibits and occasional recreational and educational events.
