Climbs on this ridge were originally completed by Michigan climbers: Brindel, Koehler, Jenks, etal. in the 1980's. Hence specific names and beta are vague. I have only listed routes that I have done. There are approximately 20 some routes on this crag. Contact firstname.lastname@example.org for beta. I will provide as much as I can. Grades range from 5.0 to 5.10+ and higher. They range from 1 to 2 pitches in length. This area in Provincial land and is open to all. Many more ridges exist in this area and, to my knowledge have never been climbed, so odds are you would be doing an FA. Most likely a person could spend the whole summer in this area and not see another climber and very few others. It is remote and bushwhacking and wilderness skills are generally mandatory. A person is supposed to get a back country camping permit. Emergency assistance is distant (from Sault Ste. Marie) and not readily available. It would take some time for SAR to find you.
Go north of Sault Ste. Marie on highway 17N. Turn off at the Stokely X/C area signs and follow Robertson Lake Rd. toward Robertson Lake. You can't miss it.
