There's a lot of debate over what qualifies as climbing an "official" fourteener amongst the climbing community. Two very common rules are that the peak must have at least 300' of prominence and that you have to have climbed 3000' of vertical gain before you can count a peak as having been climbed. Unfortunately, even these rules are somewhat ambiguous. Furthermore, any set of rules will end up including some climbs that probably aren't worthy and will discount some that deserve the title.

In order to avoid the arguments and controversy over what is official and what isn't, I've decided to make a list of everything here and let people sort it out for themselves. If it is named on a map, in a book, or on a webpage, has a spot elevation, or is otherwise noteworthy and is suspected of being above the elevation of 14,000', then I've included it here.

Sorted by Elevation

Sorted by Prominence

Notes: 

* To be ranked by elevation, a peak must rise at least 300 feet above the saddle that connects it to the nearest higher peak.

Peaks listed in green are peaks that I have successfully climed with at least 3,000' of gross elevation gain on the way. Peaks listed in red are peaks I have attempted to climb but failed. All other peaks I have not yet attempted to climb.

The notation "(+40)" indicates an error in the measurement of +40'/-0'. In this way, the data given for elevation and prominence are minimums (hence the discrepancy with data you may find elsewhere). Much of the prominence data came from this page and this page. Some of the unofficial 14er data came from the tables at the back of "Colorado's Thirteener's" by Gerry & Jennifer Roach. On the first webpage link above, note that the "interval" is the total width of the error bar, but the prominence listed is at the center of this interval. On this page I chose to use the minimum prominence, meaning that the entire interval listed here can only serve to increase the prominence. For the peaks listed here that are not on the page linked above, I consulted the USGS 1:24,000 7.5' quadrangles. The saddle elevation is not usually listed, so the prominence listed is the minimum based on the nearest 40' contour line above the saddle. The actual prominence is somewhere between the value listed and that value plus the error value (usually 40'). A question mark after the error indicates that I need to recheck this one.

A question mark after the prominence rank indicates that this peak's prominence is within the error bars of another peak's, so the exact ranking cannot be confirmed without more data.
