The agricultural landscape of McLean County is defined by a dense grid of township roads and the gentle drainage of the Mackinaw River basin. Small rural settlements like Merna and Fletcher anchor this central Illinois territory, reflecting the enduring pattern of prairie community development. The map reveals the path of the legendary Old Rte 66 cutting diagonally across the northwestern corner, serving as a modern contrast to the older watercourses like Money Creek and Crooked Creek.
