Geography[edit]

According to the 2010 census, the county has a total area of 585.86 square miles (1,517.4 km2), of which 580.69 square miles (1,504.0 km2) (or 99.12%) is land and 5.18 square miles (13.4 km2) (or 0.88%) is water.[3]

Macon County is primarily flat, as is most of the state and all of the surrounding counties, as a result of geological activity during the Pleistocene epoch. During the Illinoian Stage of the Pleistocene, the Laurentide ice sheet covered roughly 85 percent of Illinois, including all of present-day Macon County. The subsequent thaw of the region and retreat of the ice sheet left central Illinois with the characteristic flat topography which it is known for today.[4]

Because of its location, Macon County is often referred to as "The Heart of Illinois."[5]
