A view of Lake Falls in Matthiessen State Park. Mathiessen State Park is located in La Salle County near Oglesby, Illinois, a few miles south of Starved Rock State Park. It is named for Frederick William Matthiessen, who had originally owned the property that is at the core of the current park. The Upper Dells of the park's stream begin at Matthiessen Lake with the Lake Falls, which drop into the canyon below, passing through the Lower Dells on the way to the Vermillion River.
