A giant lift bridge spans the water between twin towns, its deck still rising to let ships pass. Welcome to Houghton, on the Keweenaw Waterway, the canal that cuts across Michigan's northernmost peninsula and lets boats bypass the headlands of Lake Superior. Great Lakes cruise ships dock, with no shuttle or transfer needed, at a recently built pier right along downtown: step ashore, and you've already arrived.

Copper Country

For nearly a century, the Keweenaw Peninsula supplied an enormous share of America's copper, mined from veins of exceptional purity worked long before Europeans arrived by the region's Indigenous peoples. The hills around Houghton and its twin town Hancock across the water still bristle with mine shaft headframes, chimneys, and the ruins of old mine yards. That past shows up everywhere: in churches built by Cornish, Finnish, and Croatian miners, in the grand homes of mine managers, in the street names.

Quincy Mine

On the hill above Hancock, the headframe of Quincy Mine, once nicknamed "Old Reliable" for its steady dividends, dominates the entire landscape. The site, part of Keweenaw National Historical Park, offers guided tours: an engine house home to one of the largest steam hoists in the world, a tram ride down the hillside, and a trip into a shaft where the temperature stays frigid even in the height of summer. Allow two to three hours for the full tour, and keep a sweater handy: underground, the thermometer hovers around 6°C year-round.

A University Town on the Water

Houghton today moves to the rhythm of Michigan Technological University, whose campus stretches along the canal. Its A. E. Seaman Mineral Museum displays one of the finest collections of native copper in the world, crystals and masses with almost plant-like shapes. Downtown, Shelden Avenue lines up student cafés, craft breweries, a neighbourhood bookstore, and outdoor gear shops inside 19th-century red sandstone buildings. The riverside walk passes beneath the steel bridge deck, one of the most massive of its kind anywhere in the world. One detail says a lot about the climate here: the region gets some of the heaviest snowfall in the eastern United States, several metres each winter, and students carve enormous ice sculptures during the February winter carnival.

The Gateway to Isle Royale

Houghton also serves as home port for the Ranger III, the National Park Service vessel that supplies Isle Royale, one of the least visited and wildest national parks in the United States, set far out in Lake Superior. The crossing itself goes beyond the scope of a port call, but the park's visitor centre, near the dock, tells of wolves, moose, and island forests, and leaves you wanting to come back with a backpack.

Useful Reference Points

• Docking: municipal pier right along downtown.
• Quincy Mine: about 5 km, up on the heights of Hancock; shuttle or organized excursion.
• Mineral museum: on campus, a few minutes by vehicle.
• Mild summers, cold water: bring a jacket even in July.

At the Bridge's Signal

At departure time, the great steel deck rises skyward one last time, and the two towns line up on either side of the channel like an honour guard. From this stop, you carry away the red of sandstone and metal, the chill of a mine shaft, and the feeling of having brushed against a continent of forests. Lake Superior, for its part, keeps its distance: that's its way of inviting you back.
