I also enjoyed that climb, but I did it early enough in the summer that the gully was still full of snow.Mtnman200 wrote: ↑Sat Nov 20, 2021 7:40 amI’ve done the Lightning/Thunder combo twice and enjoyed it both times.

Re: Colorado LiDAR Findings
It looks like some changes at the bottom of the BiCentennial list for the peaks at 13,580!
Mt. Powell-- 13,556
Clark Peak-- 13,579
Twin Peaks (North)-- 13,584
UN 13,580 (San Juans) -- Now 13,573
UN 13,580 (Sangres)-- No Info Yet...
Also of note for the Bi List-- Mt. Parnassus has gone from 13,574 to 13,580.
For the Peaks that were listed at 13,581 previously.
Emma is now at 13,592
UN 13,581 is now 13,587
I'd be interested in seeing the results for 13,580 in the Sangres, as well as Chiefs Head, UN 13,577 (if that's even ranked- have my doubts), and Evans B to see how those shake out.

Re: Colorado LiDAR Findings
And as previously mentioned by Ben it’s doubtful that Challenger is a ranked 14er so that would change the bi list as well…
Doing the Lightning gully with snow would be the way to go! Didn’t mind being up on the ridge but getting there was, um, “loose”.

Re: Colorado LiDAR Findings
I’m sure a lot of people would be happy to see Challenger Point crossed off the list of 14ers. I to am doubtful of its current 301’ of prominence. I think it’s a bit lower.Tufftommy-BV wrote: ↑Sat Nov 20, 2021 12:20 pm And as previously mentioned by Ben it’s doubtful that Challenger is a ranked 14er so that would change the bi list as well…

Interesting that "North Massive," having never been its own 14er under any standard, continues to not be its own 14er regardless of what time of year someone chooses to walk over to it.

Re: Colorado LiDAR Findings
I've taken a look at the low end of the Bicentennials. There is not yet lidar data available for Chief's Head, otherwise the other 16 peaks now have lidar elevations on the lidar page.Tornadoman wrote: ↑Sat Nov 20, 2021 11:44 am It looks like some changes at the bottom of the BiCentennial list for the peaks at 13,580!

Lightning Pyramid has been demoted - this will move all lower peaks up one slot in the Bicentennial list. There are several other Bicentennials that also have a chance of being demoted. See below for a list of 13ers that have <= 320' of interpolated prominence.

Re: Colorado LiDAR Findings
We'll likely have to analyze every peak in a list before that list becomes official. John came upon a surprising demotion - Lenawee, having 344' of interpolated prominence, was demoted to only having rise of 286' due to the ridgeline being higher than shown by the USGS contours. Though it's small, there's a chance that even peaks with over 320' of prominence can have contour errors, and thus be demoted. (see screenshot below)
13580 near Mt Adams was also a surprise. The 1959 contour map that Roach and others used to calculate its interpolated elevation had an extra and false contour. Today we noted that later maps (shown on LoJ) have only 3 contours above the 13,400' mark, giving it an interpolated 13,540' elevation (120' plus half a contour/ 20') - very close to the lidar-calculated 13,543'. (see screenshot below). Mt Powell is also lower than listed, possibly ferried in as well from older maps.
Today we finished looking at the soft-ranked 13ers. All beside Chiquita, that is - there isn't yet lidar available for download in its area. We've found 8 new 13ers.

Re: Colorado LiDAR Findings
1. I'll get back to you on this.Scott P wrote: ↑Thu Nov 11, 2021 6:10 pm
There are three I am curious about, but they aren't major peaks.
1. Traditionally and in guidebooks and other peak lists, the summit of Perkins Peak is considered to be the spot 7491. Listsofjohn has it listed as the interpolated point 7500:
https://listsofjohn.com/mapf?lat=40.747 ... 15&d=y&d=r
Since this is a peak I used to frequent, I'd be really curious. Personally I believe the LoJ point marked to be the true summit.
2. Here is a peak that I have done 99 times, but I'm skeptical that the highest point on LOJ is correct:
https://listsofjohn.com/peak/6564
I believe that it is slightly to the east. I brought this up on the forum, but someone said that they hand leveled it. Standing on both points, I'm skeptical.
3. When I climbed this one with my friends, his GPS on the ascent and descent indicated that this peak should be ranked:
https://listsofjohn.com/peak/6280
Of course GPS can vary, but since the results on both the ascent and descent indicated that it was ranked, I do wonder. LoJ has a note that says: May be ranked if spot elevation 6223 at the saddle is not the lowpoint.
I'd be really curious, but since it's in Moffat County, maybe LiDAR isn't available?
2. Yep, you're right. I found the high point in the eastern contour at 39.02216,-108.61754 rounding to 5750 ft. Ground a bit to the east of that is higher, but looking at google earth at that spot I believe it was catching the shrubs/vegetation 25-30 ft to the east.
3. Yeah, this one unfortunately isn't available yet.

Re: Colorado LiDAR Findings
Awesome work on sorting through the Bis, Ben! Definitely going to see some additions/subtractions. Curious what Chiefs Head turns out to be once that data is available; I am also interested to see what the results are for those other Bis with just over 300' prominence.
The lower part of the Centennial list and just below is also interesting with several tightly packed peaks. (mainly 13,811 down to around 13,800).
And of course the potential bump up one spot for all the peaks below it if Challenger turns out to be unranked. Watching this unfold is really interesting!

Re: Colorado LiDAR Findings
9! You mentioned Overlook Point earlier, promoted from a 12er to 13er. With 3 demotions, we're at a net 6 gain in ranked peaks.
This analysis is so fun to watch. Appreciate the updates as you work through the list.
