Thanks for fact checking me, djh650.
It was never meant to be a toprope anchor. It was installed some years ago as a convenience anchor and people kept working the bolts loose by toproping from it.
Thanks for the background, JC. Are there separate bolts close by for people to set up TR anchor from for Swallow Crack (granted, without rappel chains)? I didn't know that. If so, I'll be happy to spread the word on MP. Pretty sure this rappel anchor will continue to be used for a TR setup for the rest of the universe time, but any diversion of traffic is still a good thing.
After I took that photo while waiting for the TR party to complete, they lowered the climber from half way when she did not want to continue. They were happy to have us carry down their lockers for them after they pulled the rope because otherwise, they'd have to hike up to retrieve. Neither my partner nor I said anything because it was apparent that among the big group (multiple families with young kids), it was one older guy who took care of the setup for this group out there having a good time. Although I firmly believe that it's usually not a good practice for people to clip into the bottom rings of a rappel chain, I didn't want to cause any embarrassment to the gentleman, esp. when it's not an imminent safety issue.
At the Monolith, the anchor above P.O.D can be used for three routes (whether intentional or not), and I have seen people clipping into the bottom rappel rings for their anchor setup. When the opportunity is right, I sometimes say something about it and pretty much every time, I get the friendly positive feedback that , "oh, yeah, I never thought about it. Thanks for pointing that out."
