Property left unattended in Yosemite for longer than 24 hours is considered abandoned and may be impounded. However, the National Park Service recognizes that there are circumstances when it is impractical for climbers to return to fixed ropes within 24 hours. In such cases we ask that you leave ropes and equipment in place only as long as you are activelyusing the lines.
Stashed gear, food, water, and fixed ropes in particular, take away from the sense of risk and adventure that climbers and other Wilderness travelers expect to experience. Most of Yosemite's climbing areas are in designated Wilderness and must remain "without permanent improvements or human habitation… with the imprint of man’s work substantially unnoticeable."
Wilderness, and climbing in particular, is not intended to be convenient or easy (ironically that's why many are drawn to it). Please do your part to maintain Yosemite's wildness. In 2001 volunteers and rangers removed over four thousand feet of trash rope from Yosemite's walls, not including a few thousand feet of junk rope from the Heart Ledge rappels by conscientious climbers.
