About this map

Starved Rock and its surrounding canyons define the deep relief of this LaSalle County landscape where the Illinois River cuts through the bedrock. This 2018 survey documents the river's path as it flows past a series of islands, including Plum Island, Leopold Island, and Sheehan Island, while encountering a complex system of side drainages like French Canyon and Kaskaskia Canyon. The northern half of the map is dominated by the Illinois and Michigan Canal National Heritage Corridor, a vital piece of the region's historical industrial infrastructure that parallels the modern river.

Industrial and residential development is concentrated at Ottawa and Naplate to the east, and North Utica to the northwest. To the south, the terrain levels out into rural reaches near Vermillionville, where the Vermillionville Cem and the Vermilion River mark the southern edge of the quadrangle. The map reveals a dense network of township roads and county highways connecting these settlements through the high ground above the canyon system.
