Exploring British Columbia’s Most Beautiful and Most Threatened Watershed

In July, 2014, conservationists and adventurers Ryan Peterson, Travis Rummel, and Gordon Klco dropped into a mountainous fortress of old growth rainforest at the source of the Unuk River in British Columbia. Ten days and 100 miles later they floated into Burroughs Bay in Misty Fjords National Monument in Alaska having completed a first source to sea descent. The expedition was undertaken as part of production for the short film, Xboundary, which discusses the region’s transboundary rivers in light of an open-pit mining boom at their British Columbia headwaters. Downstream in Alaska, these rivers are the foundation of billion-dollar salmon and tourism industries, and residents are concerned over pollution risks posed to their economy and culture. Here, Peterson walks us through a selection of the group’s images and highlights critical portions of the trip and this fragile region. Photo: Pre-trip hopes for an all-water float trip were annihilated by aerial views of impassable waterfalls and logjams—we’d have to hike. As the cessna banked hard over the upper Unuk, Rummel filled his sick sack, portending a gnarly five-day bushwhack down the (left) ridgeline—a hellish maze of colossal deadfall, granite boulders, and thorny devils club under near-dark spruce and hemlock canopy.

Pro Tip: If you’re headed into dense grizzly country and need to buy pepper spray, there is more paperwork involved with that in Canada than there is with buying a gun in the U.S.

 •    Forested ridge. Tiring. Sloggy. Pain. Bugs. Deadfall. Hot. Bugs. Snow patches. Bugs.    •    Managed all day 2 miles.    •    This valley doesn’t cater to boating, or walking, or anything at all really. It doesn’t cater to human existence.

    •    Early start. Morning moon. Bird sounds.    •    Hope bowels hold after filtering water from mosquito bog with sheen on it.    •    Final slot canyon an easy get-down to river. A gift. A valley so green and beautiful it “obliterates memory.” (Wade Davis quote about Amazon.)

It was sighs and high fives when we reached the river on day five. What looked on Google Earth to be a casual splash and giggle turned out to be a full-on psychological thriller, with intense velocity and hydraulics pounding us everywhere toward wood and rock. Our nine-pound Alpacka Rafts were the tool for the job, allowing for nimble movement over land and water, but contact with terra firma (especially canyon walls made of sharp lava) was not an option given that they pop. Thankfully, Klco’s next-level whitewater skills carried us through with nothing more than frayed nerves.

Ninety percent of the Unuk’s rich salmon habitat is in Alaska. Meanwhile, upstream on the B.C. side, the largest open-pit copper and gold mine in North America, Kerr Sulphurets Mitchell (KSM), has been approved by the Canadian government. The developer Seabridge Gold is currently seeking a major investor to finance operations.

The Unuk’s two veiled canyons formed where the river has cut through ancient lava floes. Hundreds of miniature waterfalls pour forth from their walls, evidence of the rainforest’s spidery subterranean aquifer. Rummel, Klco, and I have been on many far-flung expeditions in pursuit of our happy sports—fishing, paddling, climbing, and skiing—but we’d come to the Unuk for the sole purpose of observation. In so doing, beauty here felt magnified by serendipity.

Ten days of ultralight travel and camping left us in awe of the aboriginal people of the region, who until the arrival of modern commerce used the Unuk as a trading corridor between coastal and interior tribes. A commodity of particular value was the Unuk’s eulachon, a small fish so rich in oil you can dry and light it with a match. Many in Alaska and B.C. still regard the river’s crossing of the border as culturally and biologically meaningless.

On day eight, just above tidewater at river mile 90, we floated around a corner to find Alaska Department of Fish and Game technicians working on a salmon study. They were the first and only people we saw on the expedition, and seemed as shocked as we were by the encounter. Here they prepare to release a sockeye salmon back into the Unuk.
(Ryan Peterson)
While the KSM mine would make a lot of money for a few people in Canada, Alaskans downstream see risk. Chief among their concerns is the engineering challenge of containing the toxic chemical byproducts that result when billions of tons of dug-up earth are exposed to air and rain. History proves that despite assurances and best laid plans, gravity almost always pulls this acid mine drainage into the watershed below a mine. The wetter and more seismically active the place, the harder it is to contain them.
