This page lists peaks in Colorado which are known to require 5th class climbing to reach the summit. A YDS rating is given for the easiest route to each summit. Also included is a list of peaks which, based on topo maps or photos, appear that they could require 5th class climbing.
The lists include ranked and unranked peaks that might be of interest (for Colorado, ranked peaks typically refer to peaks with 300 feet of "interpolated prominence"). Deciding which unranked peaks to include is very subjective. There are certainly many boulders/small peaks throughout the state that require 5th class climbing to top out on; in general, those are beyond the spirit of this list and this includes summit "boulders" sitting atop a wide summit plateaus. Those peaks listed in gray are unranked.
Another thing to note about this list is that the YDS credentials used to determine a 5th class peak is based on the Colorado version of the YDS rating system. In all the inter-mountain west states, a route with a certain YDS rating is a much easier climb than a route with the same YDS rating in Washington or California. Many climbers in Colorado like to call this the "West Coast Bias" however it should be noted the system was created in Joshua Tree, California therefore I am a believer that the so called west coast bias is the correct system. Ratings in Colorado and nearby states are easier making many more peaks suitable for this list that wouldn't be considered 5th class in the Sierras or the Cascades.
To give a quick example, many climbers who call the Cascades their stomping grounds would consider the standard route on Jagged Mountain 3rd class. Fred Beckey is one person who immediately comes to mind. It would also be important to note that I refrained from omitting peaks on this list and "sandbagging" the listed ratings....with some reluctance. You can thank Brian Kalet for providing many of the peaks on this list.
Comments, suggestions, and additional information about these and other peaks are welcome.
Yes, I've climbed Northeast Crestone. It can be tough to differentiate between 4th class & 5.0. I believe Lou Dawson's guidebook calls it 4th class, so maybe it should be left off the list. How about Peak Sixteen?
Hmmm I always thought the rock on top of Whitney was more of a bouldering problem. When I think of 5th class climbing I think of roped pitches. What do you think? I'll put it in if you think it really warrants it but I know a couple guys who just leaped up and onto the top of it.
BTW, what about the towers at Garden of the Gods? I believe there are 5th class towers there. I'll look but if you know of any let me know!
I've climbed many of the peaks on this list sans rope: Jagged, Teakettle, Peak Fifteen, Coffeepot, Peak Sixteen, Rabbit Ears, PT 10093, The Castle, South Sheeprock & Raleigh, so I'm not sure if roped pitches should be a criterion for list inclusion. So, I would add Whitney.
