The Illinois River corridor in Mason County defines the western edge of this 1981 survey, where Matanzas Island and Matanzas Lake sit adjacent to the riverside community of Matanzas Beach. Moving inland, the landscape transitions from the river bottoms to the expansive Mason County State Wildlife Refuge and Recreation Area, a significant tract of managed conservation land characterized by its many small depressions and irregular topography.
