The Fourth Principal Meridian cuts through this landscape where Henry, Rock Island, and Mercer counties meet. The village of Orion serves as a primary hub in the northeast, while the smaller settlements of Sherrard, Swedona, and Ophiem anchor the surrounding agricultural townships. The terrain is defined by the drainage systems of Camp Creek and the Edwards River, which weave through the southern portion of the quadrangle.
