Geography

According to the U.S. Census Bureau, the county has a total area of 1,459 km² (563 mi²). 1,396 km² (539 mi²) of it is land and 63 km² (24 mi²) of it (4.34%) is water.

Mason County is bounded on the south by the Sangamon River, and on the west by the Illinois River. These rivers join at the southwest tip of the County.

The soil covering much of Mason County is very sandy. This was formed during the melting of the Wisconsin Glacier about 10,000 years before present. 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 dry weather. The soil is, however, 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.
