Dinosaur Rock is home to a number of easy to moderate slab routes...and now some excellent sport climbs on its north face. There are a number of scrambling approaches from Bear Canyon, but the easiest approach is from the Mallory Cave Trail. There a couple variations on the east face and a couple on the south.

The standard descent route is to downclimb the west face route (5.0). There is a tree about 30 feet down this route that can be used for a single rope rap. There are bolted anchors on the north face.
Temporary Trail and Raptor Closures Details

Getting There

Park at NCAR, and follow the Mallory Cave Trail past Square Rock. The first major rock formation that the trail runs into is Dinosaur Rock. There will be a sign near the base showing the bird closures around Bear Creak Spire in the Spring. A good trail leads you to the east and south faces. The approach time is 30-40 minutes. Count on some extra time to get to the west face climbs.

The Flatirons Climbing Council and OSMP hosted a volunteer trail project at Dinosaur Rock last week. With the help of a lot of great volunteers, we were able to install 5 gabions to create a flat, stable staging area at the base of the crag. The east face of the gabions was camouflaged with fallen timber from the area, and the surface was filled in with dirt and small rocks. It looks fantastic! We also eliminated and restored multiple social trails along the Mallory Cave trail and installed about 15 steps and new staging areas up at Der Zerkle. Jul 12, 2016
There are a handful of new-route applications for the Autumn 2014 cycle of the Flatirons Climbing Committee's Fixed Hardware Review Committee, including one on the Matron.

Somebody left a draw on the last bolt of Patience Face. If it is yours and you can identify it, I will return it to you. Jul 7, 2014

This has to be one of the best crags in all of Colorado. It's very impressive, the routes are pretty sustained, many are a full 35 meters, and they are super good climbing. The Shaft, Patience Face, Milkbone and Ultrasaurus are all standout routes that would be amazing anywhere, and all of them happen to be right next to each other. Aug 22, 2012
Five applications have been submitted to the Fixed Hardware Review Committee (FHRC) of the Flatirons Climbing Council (FCC) for the September 2011 voting cycle:

•Two applications for new climbs, a 5.11 on the Slab and a 5.10 on Dinosaur Rock
•Two applications to add new, lower first bolts to the existing climbs Touch Monkey, a 5.11b on Der Zerkle, Dinosaur Mountain and to Short Attention Span, a 5.11d on Overhang Rock, Bear Canyon.
•One application to add an anchor to the existing climb Big Bob Cranks on Dinosaur Rock.

To view and comment on these four applications, please visit flatironsclimbingcouncil.wo…

The vote and public meeting for this cycle will be held Tuesday, December 6 at 6:30 p.m. at The Spot gym, Boulder, Colorado. Anyone interested in voting on and discussing these applications is encouraged to attend! Nov 7, 2011

Was up there 6/4/11. With the Rifle flooding closure, I encountered 15-20 (including myself) people at the crag on 4 routes. A bit crowded yes, but what worried me was the noise everyone (myself included) generated. Some hikers came down and inquired me about whether there was an accident (probably from an agonizing unsend). What I'm trying to say is as the crag is right off the trail, it would behoove everyone to be discrete while there. Jun 5, 2011
An application for a new lead climb on the North Face of Dinosaur Rock can be found here:


It has been submitted for the Flatirons Climbing Council FHRC cycle ending June 15. Any other new-route applications must be in by that date to be considered for this cycle. More info here: flatironsclimbingcouncil.wo…

Time and date of the FHRC vote and public meeting to be announced. May 28, 2011
30 to 40 minutes, depending on how fast you're hiking. There is a larger, flatter staging area for The Shaft, then a narrow (but flat) staging area for the other two, Milk Bone and Ultrasaurus. Flat ground, not that rocky, in both cases. Apr 27, 2011

How far is the approach? Is the base rather flat or rocky? Thanks for any beta. Apr 27, 2011
