Protein Supplement is a good boost to a day at Diablo. Though it's a little discontinuous, the climbing is fun and the rock is clean. Start up easy slab, then straight up a near-vertical crux to the left end of a big ledge. Continue up another steeper section to the anchor.

Edit 2016 This route has been recently retro-bolted with permission of the FA party to an all bolt route.


On the far right side of Winter Wall, the columns are oriented such that they diagonal downward to the right. This is the left of the 3 climbs in this area.

Climb 12 in the See also The original online guide photo.


Bolts to a 2-bolt anchor. A 60m rope is fine for lowering.

There's a large loose hold near the top (5th bolt or so). Wear a helmet on this one! Feb 5, 2017

Seemed somewhat stiffer than other 10a's in the area. This route and Sunbaked are steeper than they appear from the ground which, I think, somehow translates to a higher fun factor. Nov 9, 2015
I used a Yellow TCU and a .5 C4 for the first 30ish feet. Halfway up there's a place where a Blue TCU will protect, and I use that word loosely, a run out section just above the big ledge, and before pulling over the bulge. Nov 28, 2010

Mixed route put up by Tom Wezwick and Karl Kiser. We climbed an easy route to the left which probably should not be done because of bad rock near the top. Apr 1, 2008

This route was established by some combination of Mark Thomas, Tom Wezwick, Karl Kiser, and Chris Kessler, all of whom worked together on several routes at Diablo and in particular on the Winter Wall. I think Chris was the driver on this one. Mar 8, 2008

This route takes small nuts surprisingly well. I found two solid placements before the first bolt and another one after the big ledge midway through. A decent route. Dec 2, 2007
