The Grey Slabs is a fun little crag above I-70. It offers some of the canyon's best sub-5.10 routes. All day sun makes it perfect for those warm winter days.

Getting There 

Park at the Puoux pull off. Take the Superpuoux trail until you come to the old aqueduct. Here, turn right and follow the trail through the tangle of trees and rusty metal until you come to the obvious low angle slab.

Routes Left to Right 

As per the guidebook there are 8 routes at the Gray Slab and one other route, New Arrival 5.8, somewhere in the vicinity. Here they are from left to right. Keep in mind the approach trail meets the cliff between The Thread and Pinhead.

Free Range Chicken 10d, The Wave 12a, The Giving Tree 11b, Sugar Pop 10d, Smear Tactics 10d, The Thread 9+, Pinhead 7, and Via Cassia 6.

All routes equipped with either bolts, pins or a combination of the two. This place bakes in the sun, good in cool weather, but you might melt up there in the summer.

The alcove below The Wave has an impressive amount scat, my guess is either bighorn or elk, a good warm spot in the winter.

Start just left of where the approach trail hits the crag. You can see the rope in situ tie-off up above. Enjoyable climbing the whole way, not always obvious holds, seems to be the norm for this crag. Pull over the bulge crux up to the anchor. ...[more]   Browse More Classics in CO

Once you hit the aqueduct, head east along the debris for about 200 yards until you pass a large alcove. A recent tetanus shot could be helpful in this section of rusty metal and nails. Then begin angling upward and right to the base of the slab.

The trail does have some cairns here and there, not too hard to follow. The easier routes are right of the trail hitting the wall and the more difficult ones to the left.

You can see the formation from the parking below.

Hiked up there last week and was a bit disappointed. Tried climbing Via Cassia and the first hold broke off in my hands. Third pin was loose and bent. I ended up aborting since the pro seems a little lackluster. Also, another new route has been bolted just west and down from the left side of the crag. We tried it, but the first bold was a bit high for our likings. Looks interesting, though. Bring a headlamp to explore the cave behind the wood door. We climbed up and rapped off. Forgot lite though:(
