That looks delightful. Is the whole route like that?

Yes and no. A large portion of Red Rocks is covered with the black stuff which is known as 'varnish'. Pitch 3 and 5 on this route were pristinely straight varnished cracks as you see here, this pitch being the most spectacular and can be seen from the ground. The rest of the route is of a different style - a bit of face climbing, a bit with some interesting mantel and udge type moves up a wide rib in a crack, but the whole thing is fantastic. That's the thing with routes in Red Rocks - almost all the routes are of consistent grade and interest all the way up, no little 'filler' pitches. Well, they sort of have filler pitches too, but they're still 120 foot long with interesting climbing!
Another interesting thing about Birland, is the belays get smaller the higher you get. Colin, that you see here, is actually on the 5th pitch belay. Made it interesting when we offered to swing abseils back down with an american party of 6 to save time. It did save time once we got it all flowing, but took over an hour to start off, because the last person up was the one with the rope for the next belay, and each person had to come back to the previous belay before the next could get to the top. I was the first down and tried to ab two pitches in one but the ropes didn't quite reach, so had to engage in some antics with the rope of the other party to reach the belay, then sit on the comfort of the slighly bigger ledge in the sunshine and watch the antics above.
Highly recommended :)
