Pulaski County, Illinois

Pulaski County sits at the southern tip of Illinois, near where the Ohio River meets the Mississippi. Mound City serves as the county seat and is a tiny community with a surprisingly rich history.

This area was once home to the “Mound Builders.” These days, it’s mostly farmland and small communities. The county is flat and low-lying, making flooding a constant concern.

The Cypress Creek National Wildlife Refuge is, in my opinion, one of the most underappreciated natural areas in the state. Hardwood forests and wetland wildlife create an almost otherworldly landscape. For better or worse, Pulaski County feels a world away from Chicago.
