Colorado LiDAR Findings

[DArcyS]

Hey, you're in good company. Even Gerry Roach isn't a finisher anymore!

How so? Didn't he do all the 13ers also?

According to this page, currently only Mike Garratt and Ken Nolan have finished all the LiDAR 13ers. Ken actually must have just climbed his last peak becuase he wasn't at 584 a couple weeks ago. Some 13ers got added, which Mr Roach hadn't climbed, that's all. He's still a "map" finisher, just not a "LiDAR" finisher. Welcome to the pedant convention, I hope you're having fun!

It's even more fun than you think...

If we're going to be precise and accurate with measuring elevations, we might as well be precise and accurate with our language and understanding of peak lists.

Technically, it's not a "LiDAR" list. It's a "LiDAR P-300" list, which signifies that the criterion is 300' of prominence.

Next, while Roach has not finished the LiDAR P-300 list, it's more than likely that he's finished the LiDAR P-400 list (as well as all of the other "previous" 13er finishers), which would make him a 13er finisher under a different definition of a peak. This distinction addresses the issue that defining a mountain is inherently vague, and this vagueness is not overcome by accurately measuring the elevations of points on the Earth's surface.

I had a post about this issue: viewtopic.php?f=1&t=61397&p=762544

Reading an adjacent thread got me looking at the lidar list again.

It appears Square Top Mountain is the only named 12er promoted to 13k+.
And no (formerly or post-lidar) P280+ 12ers have been promoted to 13k+.
I would think all candidates in the latter group have been analyzed at this point?

Off the top of my head, Peak R? But is Peak R really "named?" Not certain if that's your angle.

Overlook Point in the Weminuche and Peak 8 in the Tenmile (not to be confused with Peak Eight in the Weminuche) are officially named 12ers promoted to 13ers.

"Peak R" isn't officially named.

If you go to the LoJ main page, on the lower left click “Lists by State” for Colorado, choose elevation range, then 12ers or 13ers, then “Get the 12ers (or 13ers) List”, you can see all the listed 12ers or 13ers. Check the 300+ box to see ranked only. Once you see the list, John recently added a column with Lidar: blank, Y, Summit only, or Saddle only. This shows what has been analyzed.

13ers ranked and unranked: https://listsofjohn.com/PeakStats/selec ... &S=CO&R=13

12ers ranked and unranked: https://listsofjohn.com/PeakStats/selec ... &S=CO&R=12

For custom lists, as long as at least one peak has been analyzed, he also added that same column so you can see what has been analyzed and what hasn’t.

Some formerly P300+ 12ers have been promoted to 13ers. No former P280-299 12ers have yet been promoted to P300+ 13ers to my knowledge (or any formerly unranked 12ers to ranked 13ers, for that matter).

We’ve looked at all the formerly soft-ranked peaks (including 12ers) that have coverage. Some formerly soft-ranked 12ers (P280-P299) still have no coverage, but I don’t think any are close to the 13er threshold mark.

Sorry, I was after "named but not ranked" and should have made that distinction. It does appear only STM made that cut thus far. Thanks!

No worries! I take it you’re curious if some of the unanalyzed close-ish named but unranked 12ers might actually be 13ers?

So after seeing some tips from various threads I decided to stop being lazy and actually put a little effort in myself to search the wealth of data folks have been collecting/sorting.

If I'm correct it looks like so far there are a total of 7 "new" 13ers thanks to the LiDAR data. I copied/pasted and added some columns of my own to make it more obvious where these are. Feel free to offer any corrections/addtions/etc.

My goal in this was to track down *any* new 13er, regardless of whether it's named, ranked, etc.

That's what I'm seeing.
The full picture also includes 13656, the new ranked highpoint replacing former 13660, now 13654.
And "King's Pawn" is neither ranked, soft-ranked (now or then), nor officially named, so it's actual significance is pretty much nil.

Well this is disheartening as I just climbed the freshly demoted Lenawee this past weekend.

Oh well, fun climb anyway!

No worries! I take it you’re curious if some of the unanalyzed close-ish named but unranked 12ers might actually be 13ers?

Yeah, that and any P280-299, though it looks like there are none promoted from that category.

I looked at Hayden, Middle Mountain, and Little Baldy recently. None cross the 13k mark. The next closest officially named 12er is now West Sheridan at 12,962'. It's unlikely that it's above 13k ft. Yeah, we tried to cover the map P280-299 ones as best as we could.

I'll also be checking some more 13ers near the Centennial and Bicentennial boundaries to make sure there aren't any further changes with those lists. Arkansas, 13975, and Garfield are not in the highest 100. It's also unlikely that 13768 is in the top 100. John's on a trip right now, so LoJ hasn't yet been updated with these results yet.
