As for climbing it, I didn't ask around or hear anything about that, but at first sight, I wouldn't think so, since the rock quality looked unsafe. I could be mistaken though, I didn't look all that close.
However, further east, as I was hiking along Rio Colca from Chivay to Callalli, I passed plenty of possibilities, and I heard that climbers go to the rocks east of Callalli:
"So I was sitting in my cubicle today, and I realized, ever since I started working, every single day of my life has been worse than the day before it. So that means that every single day that you see me, that's on the worst day of my life."
