In the two years since, the Bighorn’s Powder River Ranger District has been drafting a climbing management plan for Tensleep Canyon. “What was happening in Tensleep Canyon was not sustainable.”The plan has the potential to ripple beyond the walls of the canyon, climbing advocates say.

Currently, there are only three climbing management plans for Forest Service crags, Murdock said, though others are in the works.
