Repelling is the most dangerous aspect of climbing. Me and my buddies made it a point to double check our rigs before each of us descended.
Some great points. I’m always amazed at how few folks have prusiks and actually know how to use them.There are a lot of climbs (and canyons) where you have to rap to get where you want to go. But boy, you have to be careful. My wife and I have been climbing for almost 40 years, and we have become much more careful in the last few years.
Surprising amount of detail in the article for a mainstream news outlet:
"Park rangers and search and rescue team members observed that the man’s rope was not long enough to reach the ground on a long rappel. He tied a piece of webbing to the end of the rope, but the Park Service said he appeared to have made a mistake when disconnecting his rappel device to pass the knot joining the rope and webbing."
It's worth noting that anything that makes a process more complicated increases the risk of failure.
