The N Fork Embarras River winds through this central Illinois landscape, carving a path between the rural settlements of Moriah and Hogue Town. This early 21st-century survey illustrates a region defined by its agricultural grid and a legacy of petroleum extraction, clearly marking the North Johnson Oil Field, South Johnson Oil Field, and Bellair Oil Field. These fields indicate a subterranean economy that has long supplemented the traditional farming of Clark County.
