For such a prominent peak, Hogback inspires plenty of uncertainty. Its name is the subject of some confusion: Many visitors, and even some locals, refer to it as "Hogsback." Most maps drop the 's,' though, so we'll follow their lead. Getting to its summit isn't a sure thing, either. Unlike nearby Sugarloaf Mountain, with its wide, clearly marked single-track trail and multiple staircases on its upper slopes, Hogback forces climbers to take a series of narrow, twisty trails through woodlands, rock fields and swampy areas. With a nearly vertical rock face that demands four points of contact, the last half-mile of the climb is quite strenuous. The view is worth it, though. The rocky, nearly treeless summit offers a panoramic window on the vast, rugged forests of northern Marquette County and the endless blue expanse of Lake Superior. On the clearest days, it's just possible to see the mountains of the Keweenaw Peninsula to the northwest.
