Here is a list of new routes in the Flatirons since the FCC and OSMP began with the MOUs in 2003. Application details are in the posts below.
GREEN MOUNTAIN
Third Flatiron
*Direct West Face aka Western Skyline (5.11b; one or two pitches); FA: Roger Briggs, Dave Turner, Bill Briggs, Matt Samet, many others, 2009: A technical aesthetic, continually challenging climb directly up the lime-green arête on the west face of the Third, left of Saturday’s Folly. Begin on Saturday’s Folly for 20 feet, plug gear, then step left across the scoop to chase 5 bolts up the blunt arête. Move into a 5.10 finger crack (TCUs) through a bulge, then belay off hand-sized cams on a small ledge just above, or continue if linking pitches. From here, gear plus four bolts leads you up and slightly left, then out the big roof to finish on an exciting arête. Belay at the big ledge, then rap the normal descent; bring a standard rack up to hands (gold Camalot) size. Use longs lings if doing this as one pitch.

DINOSAUR MOUNTAIN
Der Zerkle:
•Bar None (5.8); FA: David Turner and Terry Murphy, 2004: This is the leftmost route on the southwest face of Der Zerkle — the long hueco’ed wall facing the Mallory Cave and also home to Hot if You’re Not, What if You’re Not, etc. Begin about 20 feet left of What if You’re Not, following four bolts past fun huecos to a double-bolt anchor. The climbing is slightly easier if you finish left of the last bolt, around the arête.
Red Devil:
•Hell Freezes Over (two pitches: 5.10a/b, 5.12a); FA: Chris Archer, Sarah Spaulding, Alan Higham, Nick Archer, 2004: This is the leftmost of two quality sport climbs on the south face of the Red Devil. Begin at the obvious switchback staging area below the first pitch, along the climber’s-access trail to The Box, Back Porch, etc. The first pitch is 95 feet and has 11 bolts, with the crux on the smooth lower slab (can be done at about 5.9 by stepping slightly right). Belay at or descend from double bolts. The crux second pitch starts off the big ledge and climbs past four bolts on the overhanging scoop to arête, with tough lock-offs to incut crimpers; finish far left at a double-bolt and chain anchor. You can rap the route, or scramble off left (west) from the ledge below the second pitch. Great position and views of Boulder!
•Paradise Lost (5.9); FA: Kyle Lefkoff, Tim Snipes, Strappo Hughes, 2006: This is the rightmost of two quality sport climbs on the south face of the Red Devil. Begin at the switchback staging area along the climber’s-access trail to The Box, Back Porch, etc. Follow nine bolts up a steep, featured face with cruxes coming over various bulges and negotiating left-leaning ramps. Descend from double bolts (60-meter rope mandatory). A good climb on sunny, cooler days or summer afternoons.
Dinosaur Rock:
•Milk Bone (5.13a); FA: Matt Samet, Chris Weidner, 2009: This is the left of the two sport climbs on the north face of Dinosaur Rock, right above the Mallory Cave trail. Follow 11 bolts up a sustained, gently overhanging tufa-like feature and then step left to anchors at the lip of the wall. The first bolt is about 40 feet up as you step left onto the face proper from the fourth-class ramp. Sixty-meter rope MANDATORY and will just get you back to the staging/belay area (tie a knot in the end of your rope!). Good shady testpiece for the summer months.

Chris Weidner nails the toprope FA of Milke Bone (5.13a), Dinosaur Rock, 2008. This route was completed as a lead a year later, in June 2009, and marks the first sport climb on Dinosaur Rock.
•Ultrasaurus (aka Über-Pwnage (5.13b); FA: Matt Samet, Ted Lanzano, 2009: This is the right of the two existing sport climbs on the north face of Dinosaur Rock, right above the Mallory Cave trail. Begin as for Milk Bone, clipping its first two bolts to get onto the mid-wall ledge (unclip the first bolt once you’re into the second). Now stay right up the double-overhanging corner, turn the large roof, move up overhanging huecos to a rest, and then up the black-and-green streaked headawall. 16 clips total; 70-meter rope MANDATORY (and tie a knot in the end of it). The climb finishes right at the point of the wall/rock.

FERN CANYON
The Slab:
•Shalosh (5.12a); FA: Chris Beh, Erik Fedor, Anders Fridberg, 2009: This is the nine-bolt route up the northeast-facing buttress/pillar immediately left of Family Man, on the north face of The Slab. Climb up a steepening slab to a roof encounter (5.11) to a small stance at a finger seam (small TCUs here). Move up to the base of the pillar, and then crank up ever-more difficult terrain past four bolts to a crux getting to the anchor on slopey sidepulls. A demanding, technical route.
•Family Man (5.12a); FA: Chris Beh, Matt Samet, Phil Gruber, 2008: This is the long, pumpy route through multiple tiers of roofs left of the 1980s 5.12 Boys with Power Toys. It can be identified by red-brown hangers, and starts behind a small pine tree. Climb a slab up to and through the first roof (5.11), hang on tightly for the crux second roof, negotiate more overhanging terrain, and finish up a black headwall on quality stone to double-bolt anchors. 60-meter rope mandatory. A classic for the grade.
•s00krEEm (5.13b); FA: Matt Samet, Ted Lanzano, Paul Glover, 2008; top anchors and two directionals installed by Chris Beh and Kurt Smith, 1988: s00krEEm is basically the first climb you come to when approaching The Slab on the climbers’ trail. It climbs past nine bolts on a rainbow-streaked, bulging wall on the right side of The Slab’s north face. 5.11 face climbing leads to a sustained boulder problem out the bulge, to more crimpy face moves on a headwall; finish out the big roof to an easier slab, to double-bolt anchors.

•k00kEEz n’ krEEm (5.12+/13-); FA: Ted Lanzano, Matt Samet, 2009: Find this climb as the north face blends into the west, wrapping uphill and right; it’s about 50 feet left of the 5.11d Whipping Post. Climb 12 bolts up the clean, monolithic face to a looming summit roof (60-meter rope mandatory!). The bouldery, crimpy, temperature-dependent crux comes down low, followed by more quality face climbing and a 5.12 finish.
•Sweet Niblitz (5.12d); FA: Matt Samet, Rui Ferreira, Paul Glover, 2008: This is the overhanging wall just right of Undertow, on the west face of The Slab, beginning about 10 feet right. Pre-clip the first bolt and engage a tough, shouldery boulder problem followed by 8 more bolts of pump 5.12a climbing. The route flows better if you stay left of the bolts through the middle third, though it can be done on the right. Finish at double-bolt anchors up and right.

•Hippopotamus (5.10d); FA: Paul Glover, Matt Samet, Kevin Riley, 2009: This is the short (50 feet; 5 bolts) climb on the ledge right of Sweet Niblitz. Stand high on the ledge, clip the first bolt, layback the big flake, then move into pumpy, juggy territory and up into the black scoop to finish. Anchors are over the final ledge. A great moderate and a good warm-up for the harder stuff at the Slab.
