St. Louis sits at the southwestern edge of this survey, where the winding Pine River and Horse Cr converge. The landscape is defined by the tri-county boundary where Gratiot, Midland, and Isabella counties meet, creating a complex grid of rural routes like Midland Gratiot Co Line Rd and W Co Line Rd. North of the city, the terrain transitions into a more sparsely populated agricultural area drained by Little Salt Cr and Bush Cr.
