The Mississippi River bottomlands and the rising bluffs of Adams County define this landscape near the Illinois-Missouri border. The complex river environment is marked by numerous islands and side channels, including Whitney Island, McDonald Island, and McDonald Chute. Inland from the river, the landscape transitions into a series of creek basins and settling areas like the Austin Creek Settling Basin and Fall Creek Settling Basin, which reflect local water management efforts on the floodplains.
