Begin on Sidewinder and where that route cuts left continue up over a small roof and past three bolts on featured rock to gain the prominent dike. Traverse left, clip a final bolt, (shared with Sidewinder and make the long tenuous traverse up and left to the top.

The descent is to the climber's left, where a bit of down-climbing, or a leap, will access a pinnacle with rap anchors.

  • Although essentially a variation to Sidewinder this route is equally as good and a recommended alternative if you've already done that route.


Start as per Sidewinder at a left-facing flake.


5 bolts (3/8"), gear to 3"

Randy - not "R", but maybe "PG-13" because of the traverse.

The traverse is like a zillion times scarier with high wind gusts. I did sidewinder like a month ago or something without wind, and it was scary, but not too bad. I did diamondback today (april 3) with gusts up to 23 mph (according to and was practically crapping my pants. The roof was super fun...I really wish I'd made it clean.
