The Illinois River corridor dominates this landscape, where the neighboring industrial centers of Peru and La Salle meet. The confluence of the Little Vermilion River and the main waterway shaped the early growth of these river towns, while the Vermilion River carves through the southern territory near Oglesby and Jonesville. Genealogists will find several burial grounds across the area, from Saint Hyacinth Cem and Saint Vincent Cem in the north to Oakwood Cem and Rockwell Cem further south. The topography is marked by significant features like Saint Louis Canyon and the prominent Plum Island situated mid-stream. Educational and recreational landmarks are visible throughout, including the campus of Illinois Valley Community College and the curated grounds of Forest Lawn Memory Gardens, illustrating the modern layout of these historic river valley communities.
