CO Prominence 1K' list revisions

[RyanSchilling]

Bob Martin had the chance to go through the Colorado prominence list, and offered a few revisions for me to incorporate. Some are smaller changes, fixing typos and the like. The biggest change is the addition of 4 new peaks to the list, bringing the total to 427 peaks (407 w/ proven prominence):

Wild Mountain (Rank #130)
King Mountain (Rank #387)
The Palisade (Rank #396)
Mesa de Maya HP (Rank #427)

Fun trivia.... Mesa de Maya is the easternmost 1K' peak in the state. It's not a 'proven prominence' peak, but I like how far removed it is from the mountainous areas.

Thank you for the revisions - the list has been updated. Per Layne's suggestion, the rank has also been revised to reflect equal rank for equal prominence, skipping to the next number adding the count of equal ranks.

I.e. Rank is 30, 31, 31, 33 where placeholders 31 and 32 are the same prominence (31).

Seems like an appropriate thread for posting a minor correction. The summit of Thornburgh Mountain appears to lie in Moffatt County rather than Rio Blanco County.

Ryan, you mentioned that there were now 427 peaks on the list, but both your list and John's list include 426. Was a peak subsequently removed?

[RyanSchilling]

Right you are, John, thanks! I had Thornbugh as Rio Blanco's 2nd most prominent.

Good eye about the number of peaks having changed. I forgot about this thread here, but I had to remove Mount Pisgah from the list. I had its summit elevation listed as 10490', but Bob Martin alerted me to my error. It's actually at 10390', resulting in its removal. Teller County was left with just Almagre and Rosa.

I found a new one by climbing it.

I have been visiting the points with close but missed the 1K prominence list on Shiller's web site as I do the ones with more than 1K prominence.

There is one in Moffat county which he has at 8522 feet south of the Yampa River Canyon in Dinasaur national monument.

it has thee summits 8522, 8525 and 8520+ countour.

The 8520+ point which interpolated to 8540 is obviously the highest of the three.
This 18' diff = 8540-8522 gets the drop over 1000'
So 8540 needs to get put on the list of prominenct points and upgraded to have more than 1K prominence.

[RyanSchilling]

Hey now, the name's Schilling! :D

Thank you for the notes Mike, I'll add the peak to the list.

[John Kirk]

Point 8,540 has been added to the database for members to update - nice work Mike.

I caught a pretty dramatic error I made last night involving Twin Sisters (the 13er). I had the saddle at 12,300', but it's clearly at 12,100'. This bumps Twin Sisters up about 100 places on the list.

[RyanSchilling]

Bah, I uncovered one more error while working on an ancilliary project. I found Carracas Mesa's true key saddle, which is in NM and connects the peak with the Divide. The new saddle means that the peak only has about 4-500' of prominence, so I had to remove it from the list. Carracas was a problematic peak anyway because it wasn't clear if the summit lies in CO or NM, so I'm sorta glad to be rid of it.

Back to 426!

[John Kirk]

Thanks for passing that on - I've modifed the database to reflect the correction.

[John Prater]

I think we have a new candidate for the lowest (ie, lowest elevation) 1K' prominence peak in Colorado. Point 6,100 on the Cameo quad in Mesa County has exactly 1000' of prominence.

Scott Patterson on SummitPost had alerted me to this peak recently for inclusion on the list of possible 5th class peaks, but I just now noted its prominence. I had a look at the peak a week ago driving back from Utah, and it does look interesting. Seems possible that it has enough weaknesses to keep it from being 5th class, but maybe not.

The details on Point 6,100:

Prom: 1000
Peak Elev: 6100
Peak Lat: 39.16034
Peak Long: 108.32259
Peak Quad: Cameo
Saddle Elev: 5100
Saddle Lat: 39.16517
Saddle Long: 108.3393
Saddle Quad: Cameo
County: Mesa
NHN300: Point 7,161 on Round Mountain quad

[John Kirk]

Good find! I had a feeling we'd be finding some new 1k prom peaks through this process.

[RyanSchilling]

Nice catch, John. I checked my notes, and it looks like I had misread the map and used the 5162' mark as the saddle elevation instead of properly recognizing 5162 as the elevation of that small summit along the ridge.
