The Ice Age was punctuated by several prolonged warm periods during which the glaciers disappeared entirely from the temperate latitudes and a climate similar to today or even warmer prevailed. The flood waters produced resulted in lakes; breaching of the lakes resulted in rivers and streams carving the hills and valleys we see today. In the Northwest Territory during the latter half of the 18th century, the Miami Indians were dominant in the region, but the Potawatomi and Shawnee had a significant presence. Delaware Indians, displaced from their eastern homelands by European settlement, migrated west and settled along the forks of the Whitewater River. The Whitewater Valley and Ohio River Valley area had also been inhabited earlier by other Native Americans called mound builders for their characteristic large burial mounds still in evidence today. The geological aspects of the Whitewater River Valley contributed to early settlement after defeat of the Delaware Indians by Gen. Anthony Wayne at Fallen Timbers in 1794, followed on August 3, 1795, by the Treaty of Greenville (Ohio) ceding most of Ohio and a sliver of southeastern Indiana to the United States. The valley, running south and southeasterly from east central Indiana to the Ohio River Valley, provided a convenient conduit for migration through Fort Washington (Cincinnati) from points east, settlements on the Ohio River, and settlers from Kentucky to northern and central Indiana Territory. Squatters engaged in agriculture and trading were occupying federal lands well before land sales in Indiana Territory began in 1801. An Indian trail paralleled the river from the Ohio Valley northward to the forks, then went along the East Fork to Eli Creek, thence taking a northwesterly direction passing through what was later Connersville, and then on to the Delaware villages strung along the White River from north of present-day Indianapolis to modern Muncie. Conner's Post John Conner, his brother William, and others arrived in the Whitewater Valley from south central Ohio in 1802, establishing a fur trading post in an unpopulated area near what was later to become Cedar Grove on the Whitewater River (Franklin County) at the very fringe of the European penetration into the wilderness of Indiana. By 1808, as a result of reduction of Indian hunting grounds by treaty, the trading post, known as "Conner's Post", had been relocated north on the Whitewater River junction with an Indian trail between the Ohio River to the southeast and
