Wearing Down the Mountains

Half a dozen climbers, wearing nothing more than shorts and rubber-soled climbing shoes, are gathered around a large boulder in Camp 4 in Yosemite National Park. They are all trying to crack Midnight Lightning. With its 20-ft. overhanging rock face and minuscule handholds, it presents one of the best-known bouldering challenges in the country. As yet another climber burns out after only two moves and falls back onto the mattress-like crash pad, the talk turns to the impact of climbing on the natural environment--a hot topic among climbers. Kurt Hack, 37, from South Bend, Ind., points to a cedar tree that grows right up the side of the boulder. Someone has used an ax to cut climbing steps into the trunk all the way to the top of the boulder. "Whoever did that didn't know much about low-impact climbing," says Hack.

The scarred cedar is a poignant example of the damage that climbers can do to the fragile ecosystems where they practice their sport. Camp 4 has long been home base for climbers in Yosemite, the birthplace of U.S. rock climbing. Here, where every cliff face presents an Ansel Adams moment, climbers should know better. But as the number of climbers grows--from 800,000 in 2000 to 1 million today, according to industry sources--so too does the impact they are having on the wilderness. Public-land managers, already short of funds, are struggling to keep up. Modern climbing techniques make it possible to scale rock faces that were previously inaccessible to humans. And the new craze for bouldering, a sub-discipline that focuses on short climbs, 15 ft. to 20 ft. from the ground, is bringing a younger and more unruly generation to the sport.

Certainly the depredations of a bunch of rubber-soled, chalk-bag-toting rock rats are minor compared with forest clear-cutting or strip mining. But because climbers are drawn to some of the nation's most spectacular landscapes--the Tetons in Wyoming, the Sawtooths in Idaho, Joshua Tree National Park in California--their footprints are closely scrutinized, and a nationwide debate is under way between climbers and federal land-management agencies on what and where people should be permitted to climb.

This fall the Bureau of Land Management, the National Park Service and the U.S. Forest Service are due to release a long-awaited policy on where to allow bolting--the practice of drilling bolts into cliff faces to which climbers attach safety ropes. Other contentious issues include protecting ancient rock art, preventing degradation of the base areas around climbing cliffs and minimizing interference with wildlife, such as nesting raptors. Even the chalk that climbers put on their hands to get a better grip can be a problem. Often it leaves a smudgy trail on rock faces, resistant even to rain.

"There's plenty of us who are cognizant of these issues, but you get knuckleheads everywhere," says Hack. Hueco Tanks State Historic Site, 30 miles northeast of El Paso, Texas, for example, was a popular destination for climbers until graffiti was found in the early '90s on some of the park's ancient rock art, and park officials severely restricted climbing. "Hueco was a wake-up call," says climber Tim Janke, 42. "If we fail to be good stewards, we'll lose what we have."
