This route doesn't appear in Rossiter's or Rolofson's Boulder Canyon guidebooks, but I'm sure it's been climbed for a long time. Please add a comment if you know the name of this route.

The route is a good beginner lead as it can be sewn up. The crux is brief and well-protected.


This route is the first crack system to the left of I, Robot. Walk off the top.


Standard rack. A bigger piece might ease the mind of a beginning leader. A sturdy tree at the top of the route can be tied off for an anchor.

Great route for beginners.

Great route...just a note that I found that a #4 BD wasn't big enough for the crux (if you want it). Next time I'll probably at least bring a #4.5. You can avoid the big piece by placing a cam up in the crux sidepull.

You can really sew this up with medium to big gear--very reassuring for beginning leaders. Scott mentioned his #4 Camalot wasn't big enough, but I found a place to make it work...and even climbed higher and scooted it up, so I guess I found two spots for it. :)

You can easily set up a TR from the tree at the top of this climb. I would suggest hiking up the left side to set up the TR and hiking back down vs. rapping since the top is rather blocky and would make for a slow and careful rap. Great exposure to rock for beginners.

The climbing on this route is all pretty straightforward, but I thought the crux was a little spicy and I took my time with it.

Also, I think a number 4 works just fine in the crux. You can even bring up another if you want to protect the final 4th class moves to the anchor.

A #4 Camalot works great. You could place something bigger, but it is really not necessary.
