RAIN AND WET ROCK The sandstone in Red Rocks is fragile and is very easily damaged when it is wet. MORE INFO >>>


An enjoyable route that is a little more involved than Olive Oil. Expect ocassionaly poor protection and maybe some fragile rock.

Pitch 1 - 70' 5.7 Climb a left-facing corner to a bushy ledge, traverse right along the ledge and belay.

Pitch 2 - 100' 5.7 Climb onto the top of the pillar, zig zagging up ramp until it is possible to trend up and right across the face and belay above a big corner.

Pitch 3 - 80' 5.7 Climb the crack above to a belay in the base of a loose chimney. (bring wide gear or belay off slung block)

Pitch 4 - 140' 5.7 Continue up the chimney, and when it opens up climb the right facing corner above and the face to its right to reach a belay.

Pitch 5 - 110' 5.7 Climb the right facing corner above to a large ledge. Scramble up and right finishing at the top of Olive Oil.


100 yards up the gully from Olive Oil is a brown left facing corner. Just to the left is a short steep right-facing corner formed by the right side of a small buttress/pillar. The route starts 50 yards further up the gully from this feature and is in the corner formed by the left side the pillar.


Single rack to to 3", optional 7"

Did this with my son and his buddy last week. Singles to 2" Camalot size and single nuts including single small wireds -DMM brass Wired offset sizes would have been perfect. Touching any rock inside of the chimney seemed to make it fall down onto the belayer in large chunks. I knocked more rocks on my partners out of this chimney than I have in my last 30 years of climbing total. The second dropped even more than that, almost took out the lad who was ducking under protection and the rocks did chop my rope where a single wayward loop was in the wrong place.... my son said:-( Supertopo listed 5-7" cams as optional), and if you don't have that it's a 30' ledge fall. I suspect that could have been somewhat avoided with some tiny wireds which I'd take next time.....wish that I'd had them....Otherwise...... I liked the route.

BTW, the "5.6" chimney was deemed tough by all of us.

Awesome route, clean rock, interesting pithes, varied.
A little hard to know where to go at times with many options.
Agree with first move off deck of last pitch.
we liked as well if not better than Olive Oil

Not as loose or runout as SuperTopo suggests. Definitely not as good as Olive Oil, but a worthwhile moderate route, especially in winter, with good sun exposure, a fast approach and descent, and great belay ledges. Leave the #6 at home. This one climbs pretty easy for 5.7.

Short, well-protected 5.7 cruxes at the start of the first pitch, and near the end of the last pitch. Otherwise, cruiser terrain with intermittent protection, occasionally on the fragile side. We took a #4 and #5 Camalot and placed them a couple of times; nice, but definitely optional.
