What does it mean for land to be “wild?” It’s a question that federal land managers have thought about since the Wilderness Act of 1964, which defined wilderness as areas “...untrammeled by man, where man himself is a visitor who does not remain.” Our national parks and public lands have visitor centers, fire lookouts, and other approved "installations" that help us enjoy the wild safely. But just what defines an installation has become the center of a recent debate between rock climbers and conservationists.
