Black Canyon of the Gunnison National Park has posted its proposed Wilderness and Backcountry Management Plan for public review. The new plan could impact climbing in the 2,000-foot-deep canyon in south-central Colorado, home to classic routes like The Scenic Cruise and Stratosfear.Proposed regulations include limits on new fixed anchors in the main climbing areas of the canyon, and a possible outright ban on bolts in "pristine" areas of the park. Climbers might have to get a permit before placing new bolts. The preferred alternative in the plan also discourages commercial guiding on climbing routes and would not authorize new guiding services. (The park estimates that 15 to 20 percent of climbs currently are guided.) The canyon's climbing regs would expand to cover Curecanti National Recreation Area as well.Download the plan here.
