This one is not ranked!

Nice, although I was kind of looking forward to doing it as an aid climb. Coral Rock is no longer soft-ranked now that it has been determined to be lower than 300 feet?

A friend informed me that Noel's Knob is now ranked per LiDar. Hopefully, it's really only 5.0. https://listsofjohn.com/peak/4322

Also, this soft-ranked 12er in the Gores near Red Peak is now considered ranked. https://listsofjohn.com/peak/872. I hope that one becomes a breast cancer awareness peak!
Dave,

Noel's Knob seemed 5.0-ish to me, very straightforward (but keep an eye out for lions, when I did it I saw a paw print in the snow the size of a coffee cup saucer, yikes!).

Baker Mtn in the Never Summers has a benchmark elevation higher than LoJ listed elevation by a few feet. 297 ft listed prominence. Maybe the saddle tracks.

This is fun! Steamboat Rock makes me very curious and nervous too…

North T10 is 10+ feet higher at 13,484 ft.

Or which 13253: https://listsofjohn.com/peak/543

Or which Sopris: https://listsofjohn.com/peak/860 or https://listsofjohn.com/peak/861
Interestingly enough, West Sopris is also 293' prominent so maybe both are ranked?

I'm sure there are a couple of others with identical survey summits.
13253 was a close one! Here are south and north - ground classes vs both classes respectively:

Ground: 13,257.62 (south) vs 13,257.59 (north)
Both classes: 13,258.24 (south) vs 13,257.95 (north)

Either way, the south summit wins out by inches (0.36 inches difference ground; 3.48 inches difference both classes). Both are within the typical error range of lidar, so this comparison is not conclusive.

Sopris is easier. The well-known east summit is higher, but by a foot. (12,962' vs 12,963'). The west summit IS ranked, however, at 313' of prominence.

Bross is definitely ranked at 315' of prominence. Its elevation is 14,178'.

Looks like ~141ft off the top to render Bartlett unranked

Nobody climbs 14ers anymore, they’re too crowded.

Looking forward to when lidar is available in Moffat, Rio Blanco, Jackson, and Grand counties! Much of that area is yet to be public-download-accessible. (edit)

Right now peaks 198 to 202 are all “tied” at 13580’ of elevation. Any idea how they really rank? I also assume that some soft peaks will come in above them to further alter the bicentennial list…. Thanks for posting this stuff - fascinating to follow. TT

Hey Ben,

Please educate me on this issue. When you say "yet to be accessible," what does that mean? Obviously fly overs are relatively easy. Does this LIDAR work require boots on the ground? Just curious, thanks.

Probably should rephrase that to "the LAS/LAZ files aren't yet easily accessible to the public via internet download." Based on this map (https://www.usgs.gov/core-science-syste ... tatus-maps), I'm thinking they've either already flown all of Colorado and are preparing the data, or they are "in process" of flying/conducting lidar surveys. But I'm hoping and expecting that all of Colorado should be available sometime within the next year, at least if they meet their 2022 goal.

OK, thanks for the prompt response, makes sense.
