LiDAR: Colorado 13ers and 14ers Completed

Post by bdloftin77 »

All of the ranked and unranked 13ers and 14ers in listsofjohn.com have now been analyzed. Teresa has also analyzed every contour (that we've found) with at least 240' of prominence for all the 10ers and above. There's always the possibility for more changes, but the lists should remain fairly stable now.

Bill, feel free to use elevations and coordinates from LoJ. John just asks that the source be listed (listsofjohn.com).

The Sawtooth is the only peak I've noticed that has a subjectively different summit area on 14ers.com vs LoJ (there are others whose highest contour/summit location has changed due to lidar analysis - see below). 14ers.com has the summit at the flat part above the cliffy ridge, whereas LoJ chose the middle bump since it's closer to the map label and more vertically jagged (the contour left of the "The" is erroneous).
If the current 14ers.com location is wished to be kept, here are the coordinates and elevation: Sawtooth, The|39.59036|-105.66382|13803.967|

A complete list of every 13er in LoJ can be found here.

For the 14ers and Centennials especially, great care was taken to try to exclude summit rock cairns and rock walls. For the rest of the several hundred 13ers, the analyzer tried to exclude cairns by best judgment (good summit pictures aren't always readily available). If a cairn was accidentally selected for the HP, the height difference is typically only a foot or two. If a rock appearing like a cairn was excluded mistakenly, again the height difference is only typically a foot or two above nearby terrain. Having looked at many photos for the 14ers, cairns have a tendency to sometimes appear and disappear depending on the year. If a naturally rocky summit is very small or narrow, lidar might have not hit the very top. The lidar scanning lines are typically only a few feet apart, so this shouldn't cause a great height difference in most cases.

Summary of Changes

14ers

Challenger Point was found to be unranked.

North Maroon was found to be ranked due to false/extra saddle map contours.

Conundrum Peak's summit was found to be closer to the spot elevation instead of in the small, spurious contour to the northeast.

"NW Lindsey" was found to be lower than 14,000' and is no longer in the list of 73 points above 14,000'.

"Pin Point", a class 3 summit listed in the 1932 SJM Climber's Guide on the ridge between El Diente and Mt. Wilson, was recently found to be an unranked 14er by John Kirk and can be included in the list of 73.

Note: "East Crestone" is within a foot of reliable lidar returns on Crestone Peak, and there's a possibility it might be higher than Crestone Peak.

13ers (Old map locations are listed in parentheses when summits are unnamed)

New

Not ranked to ranked

13557 (13555)
13556 (13545)
Telluride Peak
Peak Ten
13486 (13472)
Maxwell, Mount

12ers to 13ers

Overlook Point
Peak 8
13003 (12990)
13002 (12977)
"Peak R"

Unranked to Soft-Ranked

"West Eolus": In the 298.5 to 299.4999 soft-ranked threshold and just shy of being ranked. Lidar likely missed the very top of the narrow summit, and this one is very likely ranked.

Demoted

"Lightning Pyramid"
Wood Mountain
Milwaukee Peak
13509 (13510)
Rhoda, Mount
13403 (13401)
Cinnamon Mountain
Lady Washington, Mount
Lenawee Mountain
"Window Peak"
13128 (13123)
Peak Twelve
Lomo Liso Mountain
12992 (13010) (Still ranked, but found to be a high 12er)

Major Summit Location Changes (generally to a different contour)

Buckskin, Mount: From spot elevation to the NW on continental divide
"Obstruction Peak": From spot elevation to center contour
Cirque Mountain: From spot elevation to left small contour
White, Mount: From spot elevation to NE contour
**13656**: Old map location 13660 is lower than area SE along the ridge
"V 4": From center contour to right contour (eastern tower)
Ellingwood Ridge: From NW contour to SE contour
Powell Peak: From spot elevation to SE area of summit ridge
Amherst Mountain: From NW contour to SE contour
"Huerfanito": From center of large contour to far right (looks like inside a smaller contour) - eastern tower is highest

Too close to call

13258 (13253): The SE summit is barely higher, but both should be visited
13110 (13106): The ridge NE of the spot elevation is barely higher, but both areas should be visited
Heisspitz, The: The SE contour is barely higher, but both should be visited

Other notes:
"West Partner Peak" The southern bump is higher than northern one
"The Citadel" Of the two competing summits on the west, the southern one is higher by a foot

Thanks for the hard work you, John, Teresa and everyone else put in!

One note, I thought Peak R was promoted from a 12er? LOJ shows it at 13000 even. https://listsofjohn.com/peak/819

Thanks! I'll add that. Let me know if you see any other peaks/notes to add to the summary. On the LoJ peak page for Peak R, the original map elevation is shown to the right of the lidar elevation - looks like it was originally 12,995'.

Is "Pin Point" the same as "West Wilson"?

Thanks! Yeah, that is what I see too.

Interesting about Pin Point. I honestly have no idea if I went over that or not, it was not marked on any maps when I did that traverse years ago so I just have no clue if I went over it or not.
Also interesting about Heisspitz. Both summits had registers, the southern one almost looked like it was placed as a joke given both were placed by the same person and it was noted as 2' lower. :lol:

I thought 13,010 was demoted to 12,992 (NW Hossick).

EDIT: I did not see any other omissions. Great work, everyone!!

Great stuff!

As far as The Sawtooth, did I miss something regarding the actual summit being at the LOJ 13,608' point instead of the previous 13,780ish highest point?

Is this decision based on the position of the map label or is there some other historical designation that I missed?

Not that BGN is always accurate, but the location given and feature class of pillar definitely don't line up with the 13760+ contour:

Ahhh peak R you rat bastard!

Thanks to all who worked on this project. Excited to see the changes whenever they get updated here and seeing how many times I should have just tagged the 12er down the ridge...

Added - thanks! I was just in the middle of trying to find that last demoted peak.

Nope. Pin Point is #1 below, and West Wilson is #2.
