Karnak and the surrounding wetlands of the Cache River bottomlands define this portion of Southern Illinois. The landscape is a complex network of waterways, featuring both the naturally winding Old Cache River and the engineered Post-Creek-Cutoff, which serves as a major drainage artery for the region. Small settlements like Belknap and Boaz are connected by a grid of rural roads, such as Old Karnak Rd and Old Metropolis Rd, reflecting the area's agricultural and transit history.
