I tried to clean that block and it moved but seemed securely wedged. I was bummed the whole area by the first bolt of this pitch was somewhat hollow. The rest of the pitch is awesome. Goes at more like 5.10 ( must of eaten my wheaties when I thought it was 5.8) Thanks for passing on the info!
The block cleared out yesterday morning (4 July). It nearly came off when I pulled the move, so I went back and took care of it after I could get my belayer safely out of the way. It took minimal effort, so it definitely needed to go. I don't think it makes that section any harder. I'd agree with the 5.10 rating for the pitch, although mostly just because of one move. There are some other sizeable loose blocks. The one I noticed was a little left of the bolt line, maybe 5 or 6 bolts up. Great climb, by the way, and great job on the whole area. Much appreciated.
