Pickaway Plains is a wide area of rolling hills beginning about 3 miles south of Circleville, Ohio, and extending several miles to the north and south. This geological area was formed by sand and gravel deposited by melting water from the last glacier to retreat from the region during the Ice Age. During the time of inhabitation by the Shawnee, the Pickaway Plains were covered by prairie vegetation, mainly grasses.
This area was inhabited most recently by the Shawnee, who founded at least three villages here:

In 1774, the Shawnee and allied nations sent around 300-500 men from the Pickaway Plains area to meet Lord Dunmore's army of Virginia militia. Lord Dunmore was attempting both to subdue the Shawnee and Mingo, and to prevent Pennsylvania from laying claim upon present-day Ohio. This conflict became known as Dunmore's War. At Point Pleasant, West Virginia, Cornstalk and his army met a detachment of Dunmore's army under command of Colonel Andrew Lewis.
The forces met on October 10, 1774, at what became known as the Battle of Point Pleasant. After several hours of intense fighting, Lewis's detachment drove Cornstalk and his men northward, across the Ohio River. Dunmore then led his army in pursuit of the Shawnee.
Cornstalk and his men retreated to Pickaway Plains, with Dunmore's army still in pursuit. As they reached the villages, Dunmore requested that Cornstalk discuss a peace treaty. Cornstalk agreed after he received word that Lewis's detachment had destroyed several villages along the Ohio River. At the treaty, held at Camp Charlotte, Cornstalk agreed to honor the Treaty of Fort Stanwix of 1768, ceding the Shawnee hunting lands of present-day Kentucky to Virginia.
