Nice page. This might be just the way the page is rendered in my browser but the black text on the dark blue background for the #/% fields is pretty much impossible to read. So you might want to lighten up that blue background or something. Very minor issue.

Nice choice on using a high prom cutoff. For an area as large as North America you want to get significant mtns instead of little 14er bumps and that high cutoff achieves that worthy end.

Border Peaks?

Not sure if you can have multiple state/province listings for the peak locations, but you list only AK for the border peaks. These border peaks (Saint Elias, Fairweather, Hubbard, Augusta, and Cook) are also in Canada (YT, BC, YT, YT, and YT, respectively).

Guatemala Peaks

There are three Guatemalan peaks that have been omitted from this list - Tajumulco, Tacana (partially in Mexico), and Acatenango. All warrant inclusion, depending upon the elevation used for West Elk Peak (sources vary).

Re: Guatemala Peaks

Thank you for your excellent attention to detail. The list would not be accurate without your corrections. I have made the appropriate changes and I also updated the locations which you mentioned in the previous comment.

Spring Glacier?

Is there a reason that you omitted Spring Glacier Peak (elevation of about 13045 feet, prominence of about 2218 feet) in the Yukon Territory?

Re: Spring Glacier?

Steve, nice job finding this peak. It's certainly prominent enough to be included. I will add it to the list. The reason it was not originally included is due to the fact that it is not an officially named peak. The name does not appear on maps and so it is not yet listed on sites like but it did turn up on and google maps. It makes me wonder how many other unofficially named peaks are out there with enough prominence to qualify.

Where's Mt. Williamson. Should be between Rainier and Blanca.

Re: +Williamson

Williamson has 1643 feet of prominence and thus misses the cutoff. Essentially it's a very high peak with relatively little prominence. Elevation is only one way to measure the stature of a mountain. If considering both elevation and prominence in combination, then you get a much clearer idea of which peaks are most notable and significant. With this criteria in mind, you can see that only 9 peaks in the Sierra Nevada qualify.

Re: +Williamson

Well according to those stats I guess...
otherwise Williamson is easily the biggest and most prominent peak in the Sierra, interesting.

Re: +Williamson

Well, I don't mean to argue, but prominence is a word that is used loosely in regular everyday language, but when it comes to mountains, there is a strict definition, just like sea-level elevations. By this very definition, Williamson only stands up 1643 feet above the saddle connecting to the next higher peak (Whitney).

I have no doubt that Williamson is an important peak for California by elevation alone, and a worthy mountaineering objective to boot. In fact I plan to climb it myself, likely this year. But this list was specifically tailored to exclude high peaks which don't stick up much on their own and are generally part of a larger massif. Without this measure the list would have been skewed in favor of areas like Colorado and the Sierra Nevada where there are a lot of high peaks with very little true prominence.

Have you ever read the formal definition of prominence in regards to mountains? I can offer a link if you are interested. I'm actually not surprised if you have not seen this information clearly defined before. Most people I have talked to have no idea what true prominence is outside the loose connotations of the word.

Re: +Williamson

Oh, I don't really care that much i was just making an observation I think it's at least 300' up from a col constitutes a peak or something like that. Enjoy your climb of Williamson!
