About this map

Trilla and Johnstown anchor this central Illinois landscape, where the flat upland prairie is deeply etched by a network of southward-flowing drainage. The map reveals a transition from the agricultural grid to the meandering paths of Clear Creek, Muddy Creek, and Bear Creek. These waterways dictate the placement of several local landmarks, including Lake Louise and a series of burial grounds such as Bear Creek Cem and Upper Berry Cem.

Transportation infrastructure reflects both modern and local aviation history, with the presence of Thornton Airport and the Cumberland Air Park RLA Airport near the settlement of Neal. The extensive county road system, featuring routes like Co Rd 1300 and W Trilla Rd, provides a clear view of the rural property divisions and small communities that define this part of the county at the beginning of the twenty-first century.
