According to the book "Rock and Ice Climbing Rocky Mountain National Park: The High Peaks" by Richard Rossiter there are different routes on each pitch of the Flying Buttress varying from 5.7-5.10. As far as I can tell, there is no way to the top without climbing at least one section of 5.10. If you avoid the huge 5.9 roof the alternative is a 5.10 face climb. Refer to the book or the Bernard Gillett book for details. This is a world-class climb on great rock with unbelievable exposure. There are a few fixed pitons along the route.

The route was more than a little above my skill level. I free-climbed all pitches except one 30-foot stretch of 5.10 on pitch one which was an amazing lead by my partner Greg Williams. On that piece I hang-dogged on the rope and did what I could to get to the top. I sure as hell didn't get any style points but it was great being there, and I learned a bunch.
