Presque Isle - D) 'Bottom Presque': South Boundary Rd to Lake Superior (1.1 miles) (MI)
Almost certainly too low for whitewater run.
Pick a line that you like! Depending upon where you run this, it may be an easy, sliding drop (far left), a series of short ledge drops (more toward the center), or a big ledge to launch a boof (well to river-right).
