Nestled deep in the heart of the High Sierra, the 211-mile John Muir Trail traverses three national parks, one national monument, two national forests, and four wilderness areas. Passing through some of the country’s most dramatic and beautiful natural landscapes on its journey from Yosemite National Park to Mount Whitney, the trail is—deservedly—a destination for hikers from around the world. The region is a jewel in the crown of the United States’ protected wilderness, where one can be inspired by the raw, untrammeled beauty of Nature, along with your fellow hikers and backpackers. It is an area that takes time to penetrate but is within a relatively short drive of 40 million people. As such, the main threat to this breathtaking landscape is not logging, mining, development, or road-building. Instead, the Trail is the victim of its own success, threatened by the continuous micro-impacts of each visiting hiker. While one boot print won’t cut a new trail through a meadow, a thousand such boot prints might, damaging the delicate ecosystem of the High Sierra and, sadly, leaving the trail a little worse for hikers’ having been there.
Recognizing the problem is the first step to solving it, with hard work and conscientious visitors, the trail and the wilderness made accessible by it can be recovered to a near pristine state. There are currently multiple efforts underway that anyone can assist with, a combination of prevention and restoration.

In the case of the John Muir Trail, the old adage holds: an ounce of prevention is worth a pound of cure. Happily many agencies and nonprofits alike are mobilizing to educate the public on best practices and promote sustainable use of the wilderness. The National Park Service and the US Forest Service require permits for all through-hikers hoping to travel the trail in whole or in part. Assigned fairly to all hopeful hikers via lottery, these permits ensure that the trail operates at, not above, capacity during the most popular summer months. In addition to limiting the number of hikers, the permitting process also serves to educate visitors about the importance of “Leave No Trace,” a movement to minimize the impact of hiking and camping. Known to many hikers as simply “LNT,” the phrase has become a shorthand for a set of guidelines ensuring sustainable outdoor recreation: be considerate of others and wildlife, carrying your trash out with you when you hike, use existing trails and campsites, preferably on durable surfaces to limit erosion, and leave things as or better than you find them. We certainly encourage people to visit this spectacular region, but we ask all to be respectful of everyone who wants to experience it also.
The proverb “when you find yourself in a hole, the first thing to do is stop digging” is appropriate. Following principles of LNT will minimize further damage. Getting out of the hole and fixing the current situation, requires a considerable amount of restoration effort. Physically, restoration efforts are difficult on the Trail’s many miles of high alpine wilderness. Above 8,000’ elevation, with, at best, three to four months between snow-free and first snow, there is little time to conduct boots-on-the-ground restoration. In the wilderness locations of much of the Trail, all work efforts must be accomplished with hand tools—no jackhammers or chainsaws to build trail or clear debris. Moving rock and sand, aerating soils to regrow meadows, placing debris dams to slow erosion, takes long hours with shovels, picks, and heavy wheelbarrows on rough terrain. Additionally, a crew’s supplies – food, bedding, and clothing – must be packed in for miles by mules. The romance of packing in the very same way that Ansel would have lugged his photographic equipment is vivid, but wears off quickly.

Given these difficulties, every effort is a multi-year commitment, and results can take time to show. Coordinating with the multiple agencies involved is difficult, but almost necessarily so. Work half done is not effective, and if the agency can’t be assured of multi-year funding for restoration projects, there is a long backlog of needs. There are two organizations working in the area that have made significant contributions to restoring these wilderness areas – the John Muir Trail Wilderness Conservancy and the Yosemite Conservancy. The Yosemite Conservancy has been dedicated to helping Yosemite National Park for decades, and provides the National Park Service with funding for many needed diverse projects that Congress won’t.

The John Muir Trail Wilderness Conservancy is far younger, but has made amazing strides in a short period of time. It covers a narrower focus – restoration – on a much wider scale. You can learn more about them here and here. In addition to coordinating and supporting the restoration of the wilderness and improvements to trail infrastructure, both Conservancies fulfill an important mission for the well-being of the trail and its environs. More than just repairing damage done by hikers, the important work of the Conservancies helps protect all Californians. Traversing the headwaters of the state’s most important aquifers and watershed areas, a healthier Trail means cleaner, fresher water for all. As the line connecting many of our most treasured public lands—running through Yosemite, Kings Canyon, and Sequoia National Parks—the JMT stands as a symbol not just for where conservation efforts have been, but where they’re going: uniting every lover of the wilderness in the fight to preserve it.
