Okay, here's an obsessive/trivial/stupid question for those with spare time to ponder.
There's a photo of Art Gran on page 222 of the latest Williams guide to the Trapps. The caption says it's Thin Slabs Direct. But I'm pretty sure it isn't. The formation Gran is standing on bears a superficial resemblance to Thin Slabs Direct, but apart from the basic outline of the rock, everything is wrong. The featured crack (which holds all the pins) is missing, there's a section of rock jutting out to the right (at the top/right corner of the photo) that's totally wrong, and there's a rope supporting Gran from directly above that would make absolutely no sense if Gran were actually doing Thin Slabs Direct.
There's a great photo of Thin Slabs Direct in the Dumais book, on page 102. Compare the two and you'll see what I mean.
So which climb is Gran actually doing?
