PARKIN, ARKANSAS—Archaeologist Jeffrey Mitchem of the Arkansas Archeological Survey has sent a sample of a wooden post first unearthed at Parkin Archeological State Park in 1966 to David Stalhe, a tree-ring specialist at the University of Arkansas at Fayetteville. According to a report in Arkansas Online, carbon dating of the bald cypress post in 1966 indicated that it was cut between 1515 and 1663. Mitchem’s team has rediscovered the posthole, which measures about 35 inches in diameter and is more than five feet deep. Some have speculated that the post was part of a large cross said to have been erected by Spanish explorer Hernando de Soto at a village called Casqui in 1541. “The best indication we could have is if the carbon-14 testing says it’s from 1541,” Mitchem said.
