Presque Isle Potholes
The Presque Isle Potholes are found near the mouth of the Presque Isle River in Porcupine Mountains State Park. A swinging cable bridge spans the river and offers the best views of this unique geological feature. It is thought that the bowls were formed by boulders caught in eddies. While swirling around, these loose stones "drilled" holes in the riverbed.
Manabezho Falls is the crown jewel of the Presque Isle River. A wonderful overlook offers a great view from downstream. The ever changing look of the waterfall can be seen in the variety of water levels in the pictures I have posted here.
Manido Falls, one of the wonderful waterfalls on the Presque Isle River, lies upstream from Manabezho Falls. Interestingly carved bedrock, looking like sculpted milk chocolate, extends some distance below the falls. During lower water levels it is possible to see much of it as the river, during those times, flows along the northern side of the riverbed.
The uppermost of the "classic" Presque Isle River waterfalls is found not far from South Boundary Road in Porcupine Mountains State Park. The stair-stepped layers arc around a corner as the river begins its final approach to Lake Superior, falling over four waterfalls and their associated secondary drops.
