Points of interest
There is a limestone outcropping due southeast of Iuka, IL that is one of the purported locations of Burrows Cave. In 1982, Russell E. Burrow claimed to have found numerous archeological artifacts in this cave inscribed in Ancient Egyptian and Greek.Today, Burrows Cave is considered a hoax by most mainstream archeologists. The myth remains active among Iuka residents. Along U.S. Route 50, 0.5 miles north of the village lies the Halfway Tavern, a replica structure of the original that lies halfway between Vincennes and Saint Louis. It is claimed that Abraham Lincoln stayed at the inn, though there is no proof of his presence at the tavern. It is also believed that a group of Native Americans robbed gold from a passing stagecoach in the early 1800s, and that the gold is buried in a wooded area to the north of the tavern, but cited evidence questions the legitimacy of this claim. Further east along U.S. Route 50 lies the Hebron school, a wooden one-room schoolhouse that operated between 1908 and 1952.
