I've done route 6 a couple times before, and 5.10 it ain't, at least how I climbed it. I started a bit right of where the route is in the pic. It protects reasonably well on trad gear. It's been a couple years, but I remember it being only 5.6 or 5.7. I've taken complete beginners on this rout and they did it without major difficulty.

Thanks Tristan. I've since learned that there are two named routes there (now numbers 5 and 6 in the updated picture), both apparently by Jim Knight and the names have something to do with K-Mart.
