History

Mason County was created in 1841 out of portions of Tazewell and Menard counties.

Geography

According to the U.S. Census Bureau, the county has an area of 563 square miles (1,460 km2), of which 539 square miles (1,400 km2) is land and 24 square miles (62 km2) (4.3%) is water.

Mason County is bound on the south by the Sangamon River, and on the west by the Illinois River. These rivers join at the county's southwest tip.

The soil covering much of Mason County is very sandy. This was formed during the melting of the Wisconsin Glacier about 10,000 years ago. Meltwater from the glacier deposited large amounts of sand in a delta region near at the junction of the Sangamon and Illinois Rivers.

The sandy soil does not hold water well, quickly exposing crops to drought conditions as the water table drops during periods of low precipitation. However, the soil is very good for growing vegetables that are otherwise not common in Illinois. Modern irrigation has made this a highly productive agricultural area.

A sand wetland on the Illinois River is managed by the U.S. Fish and Wildlife Service as the Chautauqua National Wildlife Refuge.

In recent years, average temperatures in the county seat of Havana have ranged from a low of 14 °F (−10 °C) in January to a high of 88 °F (31 °C) in July, although a record low of −30 °F (−34 °C) was recorded in January 1999 and a record high of 106 °F (41 °C) was recorded in July 1983. Average monthly precipitation ranged from 1.85 inches (47 mm) in January to 4.43 inches (113 mm) in May.
