Smack dab in the middle of the Quarry Wall, and very obvious from the hike in, is a large flake that resembles the profile of a person looking to the South. Undertow follows this flake / right-facing corner to a bolted anchor near the top of the wall. The climb is a good mix of smearing, laybacking, jamming, and powerful underclings.

There's an optional two-bolt start that joins the route after the initial undercling, but the complete flake, starting at the base, makes for a more continuous climb.


This is in the middle of the Quarry Wall.


Single set of cams to 4" or 5", your big piece can be placed early on.

This is a very worthy climb, especially once you've climbed the classics at Thunder. We did the bolted start, which is a nice option if you didn't bring the larger gear. I thought the crux of the route was placing the gear as you work left to right across the undercling flake. You get good gear, it's just a bit strenuous and awkward to place, so no reason not to get on it. Gear recommendation: 2 x green Alien size to #1, 1 x #2.
