This from the ZNP Wilderness Guide 2019 REFRIGERATOR CANYON On September 20, 2014, a group of eight people, including a thirteen-year-old boy, attempted the Refrigerator Canyon route. The boy attempted to rest by tying off his rappel device when he was about 40 feet off of the ground. He lost control while completing the tie off and fell 20 to 40 feet. A prussic caught him before he impacted the ground, but he still suffered back and chest injuries. The boy’s prussic backup prevented more serious injuries. Do you have a backup for all party members? Can all members of your group stop mid-rappel or ascend a short distance to correct a problem? If not, consider taking a canyoneering course before heading out on your own. Tom says: other than spelling prusik wrong, any comments on this accident report?
