This is a quarry visible at the north end of the Flatirons not too far above the Mesa Trail, south of the 3rd Flatiron. The rock is clean, quarried, 65 degree angle sandstone. There are some bolted slab routes to 100 feet here listed in Boulder Climbs North. The fixed gear is dated so consider Screamers or don't fall too far. Probably for those into the obscure hit list.
Getting There
Hike the Mesa Trail either N from NCAR or S from Chataqua to S of the 3rd flatiron. [There is now a well-maintained trail to the quarry, marked with signs, leading right (northwest) as you approach from Chatauqua Park.]
Routes
L->R:
Left Arete, 5 R Non-Friction, 8 R Middle Way, 10 X Diatribe, 10 X Quarry Wall, 8 Don't Stop Now, 9- X
The only fully bolted lines have new bolts. (It appears that no new bolts have been added.) I believe there are 2 lines, plus, on the very right side, a single modern bolt about 1/3 up the wall on a line that maybe can take some additioanl pro. More TR's are possible. Bouldering along the base of the slab is quite nice, too.
