Mount Franklin was named in honor of Benjamin Franklin. It’s along the Greenstone Ridge, about which Summit Post says:
The Greenstone Ridge forms the geologic backbone of one of America’s least visited National Parks…Isle Royale … The island is composed of a series of ridges that run the length of the island. In between these ridges are areas of swamp and muskeg. Sound inviting?
The Greenstone Ridge is the longest and highest of these ridges. It gets its name from the greenish stones that are commonly found along it. It runs the entire 45-mile length of the island and is anything but smooth. A few notable peaks along it include Mt. Franklin(1080’), Mt. Ojibway(1136’), Mt. Siskiwit(1205’), Ishpeming Point(1377’), and Mt. Desor(1394’). The ridge top is quite open in places, particularly along the northeast half of the ridge. The trail between Mt. Franklin and Ojibway is especially scenic.
