Prominence technical Q - NH200 list

[Oncoman]

Concerning NH200 list

Long Mtn 3661’ P = 1711’ (Lat = 44.6798; Lon = -71.3796) Prox. Parent = Sugarloaf
Long W. Pk 3661’ P = 1711’ (Lat = 44.6696; Lon = -71.4023)Prox. Parent = Sugarloaf

1 peak with 2 identical shoulders or 2 separate pks ? (col = 231’ between 2 pks)

Also

Huntington 3700’ p = 840’ (Lat = 44.0502; Lon = -71.4912) Prox. Parent = Hancock
Huntington S Pk 3700’ 2 bumps p = 840’(44.0464; -71.4850) & (44.0470; -71.4834)
(Col = 200’ between 2 pks)

My opinion is that if one uses the pragmatic rule that a pk must rise on all sides by 200' interpolated, than we have 4 seperate pks for above; but if we use the conventional interpolated prominence rules than we have only 2 pks and 2 additional pks need to be added to NH200 list + 15 others to compensate for 16 pks with less than 200' of prominence & adding Guyot which qualifies with p = 200'

Any prominence experts out there who can confirm...

I have no clue what NH200 list you are using, but using 200' cols all 4 should count

The original NH200 list was basically all peaks over 2900' with ~200' cols

But since this is not an official list anybody can make a list and put whatever peaks they want on it and call the list anything they want

Even the AMC 4k list has a peak which definitely doesn't have a 200' col unless the contours on the map are wrong, and a couple others which probably don't

Prominence based list. Rules are rigorous:

1. Only info from current official maps can be used.
2. Unless stated on maps, values for elevations & key saddles are interpolated
3. All values are given in imperial units. If conversion from metric units is required, units are rounded to nearest units (eg 2745.45' = 2745' ; 2745.50' = 2746')
4. All peaks must have a minimal prominence of 200', interpolated if necessary
5. No minimal distance between peaks are required

That being said I for one feel that for tradition's sake & for respect to former peakbaggers all disqualified pks whether on official or non official lists should also be climbed
