Illinois Illinois (/ˌɪlɪˈnɔɪ/ ( listen) IL-i-NOY) is a state in the midwestern region of the United States. It is the 5th most populous state and 25th largest state in terms of land area, and is often noted as a microcosm of the entire country.[7] With Chicago in the northeast, small industrial cities and great agricultural productivity in central and northern Illinois, and natural resources like coal, timber, and petroleum in the south, Illinois has a diverse economic base and is a major transportation hub. The Port of Chicago connects the state to other global ports from the Great Lakes, via the Saint Lawrence Seaway, to the Atlantic Ocean, as well as the Great Lakes to the Mississippi River, via the Illinois River. For decades, O'Hare International Airport has been ranked as one of the world's busiest airports. Illinois has long had a reputation as a bellwether both in social and cultural terms[7] and politics.
Sangamon River The river rises from several short headstreams in southern McLean County that arise from a glacial moraine southeast of Bloomington-Normal, Illinois. Part of the moraine is publicly owned as the Moraine View State Recreation Area. The river's course forms a large arc through central Illinois, first flowing east into Champaign County, Illinois, south through Mahomet, then west through Monticello and Decatur, then turning northwest to flow along the north side of Springfield. It receives Salt Creek at 40°7′33.24″N 89°49′30.36″W﻿ / ﻿40.1259000°N 89.8251000°W﻿ / 40.1259000; -89.8251000, approximately 25 miles (40 km) north-northwest of Springfield; then the river turns west, forming the southern boundary of Mason County with Menard and Cass counties. It joins the Illinois River from the east just north of Beardstown.[2]
