The borderlands of Fulton, Knox, Warren, and McDonough counties meet in this agricultural landscape centered on Avon, Illinois. The town sits at the intersection of local routes like S Main St and W Warren St, serving as a hub for the surrounding farm country. Further north, St. Augustine anchors the Knox County line, while Prairie City occupies the southern edge of the sheet. The terrain is defined by a dense network of drainage, where the headwaters of Cedar Creek and Swan Cr carve through the prairie, and Avondale Lake provides a notable water feature just east of Avon.
