The Parkin site is a 6.9 ha (17 acre) late Mississippian and protohistoric pyramidal mound and village site in northeast Arkansas. It is the largest of 21 known Parkin phase sites and was probably the capital of Casqui visited by the De Soto expedition in 1541. Parkin is strategically located below the junction of two rivers, convenient to receive tribute. Parkin phase sites are located on areas of very productive soils and may have supplied food to the Parkin site itself. No farmsteads were found despite an intensive survey in a 1 km circle around the Parkin site. All known sites appear to be fortified, possibly a reaction to increased warfare.
