The border of Edgar and Clark counties in Illinois defines this landscape, where the agricultural plains are deeply incised by the drainage network of Mill Creek. This waterway and its numerous tributaries, including Sevenmile Creek and Ennis Creek, create a dendritic pattern across the terrain, culminating in the Mill Cr Impoundment Number 2 Reservoir to the south. The small settlement of Martin and the Perry Airport sit on the higher, flatter ground near Tarble Lake.
