How many Colorado 12ers are there and who was first to climb all of them??
YouTube video - climbing Bison Peak in Colorado's Lost Creek Wilderness |
According to a December 17, 2010 Examiner.com article, by Jilly Salva; Bob Martin, Mike Garratt, Ken Nolan, Jack Dais, and Teresa Gergen were the first five people to have climbed all of Colorado's 12ers.
In the article, Salva asks Gergen, the first woman to complete all 1,313 of Colorado's ranked peaks over 12,000 feet, how many 12ers there are in the state: "To answer that requires a little preliminary explanation. The elevation lists count "ranked" peaks. A ranked peak has at least 300 feet of prominence, or, in simple terms, rises at least 300 feet above the saddle connecting it with its next higher neighboring peak. Whether or not a peak has a name is irrelevant. Secondly, climbing 'all the 12ers' means climbing all the ranked peaks over 12,000 ft. There are 53 ranked 14ers (El Diente and North Maroon are unranked, and Challenger is ranked, hence the deviation from the traditional number of 54 14ers in the state), plus 584 13ers, and 676 12ers, for a total of 1,313 ranked peaks over 12,000 ft." Having lived in Colorado most of my life, I probably climbed a couple dozen "12ers" either intentionally or by accident, by age 50, while looking for other peaks (especially before the days of GPS!). Unfortunately I didn't think of creating this page or recording any of those climbs until I accommpanied Sacha Bobst and Tom and Linda Jagger up Bison Peak (12,431 ft) on Veterans Day '11, when I was 55 years old... After such a fun hike, through mixed conditions (some snow and ice), it seemed a good idea to start tracking 12ers with something more than just a "went hiking today" note in my outdoor log! So, as time permits I'll start entering my 12er data and pix here as I complete new peaks or find records of ones that I climbed in the past. Either way though, it's clear that 12ers can provide their own challenges, especially in winter, despite being considerably lower in elevation than that of the 13ers and 14ers I describe on my other pages. |
Humphreys Peak, Arizona (12,663 feet / 3,859 metres)
Humphreys is the highest peak in Arizona - with views (when it's not "misty" like the day I climbed...) of Grand Canyon just to the north. There are a few different routes up Humpreys - I started at the Arizona Snowbowl for the standard, 1,006 metre (3,300 feet) route up...

Bison Peak, Lost Creek Wilderness, Colorado (12,431 feet / 3,789 metres)
Linda near the top!The Lost Creek Wilderness (LCW) Area protects almost 120,000 acres in the Tarryall, Platte River and Kenosha mountain ranges in central Colorado. This relatively new wilderness (designated in 1980) is loaded with hiking, backpacking and climbing possibilities. Typical LCW landscape will consist of mixed and very dense forests, open meadows, small streams; somewhat the norm for Colorado's high country. Upon first sight, it's possible the casual climber or mountaineer may not be too impressed with the typical LCW mountain configuration. Dense, tree- laden slopes that frequently lead to tree-covered summits could easily rekindle a forgotten bad memory, a memory that includes your most frightening bushwhacking experience.
However, despite lacking the grand alpine scenery of other Colorado wilderness areas, one can argue that LCW may be one of the most unique Wildernesses in Colorado. Upon closer inspection the LCW has its own character that no other place in Colorado can match. Character that includes some of the most bizarre rock formations you will ever see. A lot of the LCW is dominated by these incredible rock formations, including massive polished granite domes and towering spires. With elevations ranging from 8,000 to 12,400 feet, many of the mountains here sport huge, wide-open plateaus providing easy hiking and excellent views. Getting to those plateaus is another story.

Glass Jar Summit Register on Unnamed 12,915:
Glass Jar Register
Roger and the RegisterOver the years I've also encountered dozens of "unofficial" summit registers - like this one inside a glass jar atop Unnamed Peak 12,915 feet (Near Mt. Lindsey). I would be curious to know who maintains these and where they're eventually archived - please email me if you have any info on the subject! Unfortunately I've discovered many of these glass jar summit registers either cracked, broken, or the lids so rusty that water leaks through and destroys the paper. So, I often try to air 'em out a bit when I find they're wet and then place them in a well protected portion of rock, on the summit, that's obvious for other hikers to find. Either way, it's always fun to find summit registers, even when they're on peaks as low as 12 thousand feet (3,657 m)!

12er Waypoints

For personal safety, and just for the fun of it, I usually take a GPS "reading" on the top of each peak, at the trailhead, or some other interesting point or curiosity along the way. WARNING: I cannot guarantee the accuracy of these waypoints as my own GPS bounces around a lot or I simply take an incorrect reading! Please rely on a more accurate source for your Waypoints! That being said, I still enjoy "cataloging" Waypoints and I keep a bunch of other locations, from around the world, on my 13ers, 14ers, Hiking, Waypoints, and other pages...

Some Trailheads:
Prominence, a Definition:
In topography, "prominence" is the height of a mountain or hill's summit by the vertical distance between it and the lowest contour line encircling it and no higher summit - Prominence is a measure of the independence of a summit. Only summits with a sufficient degree of prominence are regarded as independent mountains. For example, the world's second-highest mountain is K2 (height 8,611 metres, prominence 4,017 metres). While Mount Everest's South Summit (height 8,749 metres, prominence about 10 metres) is taller than K2, it is not considered an independent mountain because it is a subsummit of the main summit (which has a height and prominence of 8,848 metres).
