Nice to see a Rattlesnake photo on MP (I know it's not new, but this is the first time I've come across it.) I think "Ikenseaor" is meant to be said like: "I can see your". Never took the fall at the crux on that one. But it looks like it would be exciting.
THE CATHEDRAL at RATTLESNAKE The route is Arabesque(.10a steep!). Draws to the left are on The Groove(.12a small pockets). Left again is Ikenseaor Crack(.11d). Perhaps meant to be said "I can soar" because the crux dyno out of the crack into a chimney/stem is a bit run. Top roping it, the fall looked uniquely horrifying but clean. The welded tuff is sharper than Smith yet worthy. Almost one hundred sport routes. Rattlesnake is four air miles west of Trail, Oregon, between Crater Lake and Medford. The book Rock Climbing Southwest Oregon by Greg Orton has great directions.
