Frogmore Mound, which is listed on the National Register of Historic Places, is a pristine platform mound with an associated village site. It’s 14 feet tall, measures about 160 by 190 feet at its base, and is about 60 by 70 feet on the summit. The mound and the village midden (trash heap) cover an area about 400 by 200 feet, some of which has been covered by flood sediments. Excavations show the mound was built in two stages, a short length of time apart. It was built over a walled, probably ceremonial, structure about 20 to 30 feet in diameter, which was burned and covered with dirt before mound construction. Charcoal from underneath the mound dates to AD 1020–1260, and ceramics from the midden also indicate occupation late in the Coles Creek period.
