Pardon my ignorance but how does one calculate or measure prominence?

Tom Rankin · Jan 3, 2009

If no one has done it, I'll bet Spencer (aka peak_bgr) is the closest! His goal is to hike every ADK mountain named on any quad map, and I believe he has over 800 to date!

Brilliant!
A nice new list for us prominence freaks.
Alas, I can only claim twenty of these... so far....

Short answer: The prominence is the height of the peak above the col to the next higher peak. It's used to distinguish "real peaks" (like Katahdin) from mere bumps on the side of real peaks (like Clay). The AMC White Mountain 4000 footers (aka the 48) uses a 200' prominence rule which you may be familiar with under other names.

Long answer: read this.

Interesting.

Just out of curiosity, how can a pond or a lake be a saddle? Boreas Pond, Fawn Lake, and others are listed in the "saddle" column. I haven't checked the quad maps, so the info here could well be correct, but I'm just interested in the theory of how a standing body of water that has shores could be the highest point at the saddle. Wouldn't there have to be some embankment on at least one side to keep the pond from draining into either side of the saddle? (Unless the summit was an island in the pond...)

Did you compile this list, PB? I started trying to come up with a P1000' list for NH but abandoned it because it was a TON of pretty darn meticulous work!

Wow, that's AWESOME. Did you put that together all yourself?

Alas, although I live in NY (NYC to be exact) I'm almost entirely a New England Hiker. I did complete the New England Fifty Finest (to use a title that gets some folks indignant). See my signature for that link. As for the ADKs - maybe next year

.

I do believe any of these prominence lists are great since they get you to a wider geographic area (since generally just the highest peak in each range will make it to such a list), and you get to some peaks you would never otherwise get to.

I said compile, not complete...

Compile, no. The only prominence list I ever worked on was for the Torngats which I did with Greg Slayden in 2004 (see).

This was list was Roy's, who with Edward Earl collaborated in producing a list of all peaks with 1000+ feet of prominence in NY State. Check the recent messages in this Yahoo Group: Prominence group

I started working on this as well sometime last year but never got around to finishing it. I was going to ask the same question. Nice list! I really like prominence lists because, like I've said before, they give you an interesting look at an entire mountainous region and don't just cut off below a certain height threshold (4k list) or have too many peaks on it for me to feel motivated towards climbing (3k lists).

It would be possible if the lake had two outlets, in opposite directions into two separate watersheds. That might be the result of human or beaver constructions. In the large marsh area that separates the Boreas Ponds from the Ausable Lakes watershed it might be natural. But I suspect in most cases the saddle is just very near the lake on a shallow embankment. It may have been just more concise to identify the critical col / saddle as the lake.

That answer is correct, usually the lake name is just used to identify the col (as are road names, often the road isn't at exact low spot) but on some lists there are some lakes/swamps with 2 or 0 outlets shown on the map.

EE & I made separate lists and compared them, I believe he did it all online while I visited a lot of libraries to look at paper maps.

the last fontier...

Hi Roy.

Last monday in Owl Pate, the rabbit finished this nice new challenge....Onconman e-mail Us We will need only 13 summits after the 3,000Adk feet list and We think it will be a nice thing to go in this way.

We will try to made the same thing in the next Winter season!!

But this new goal will be in a second place for the next Winter.....

It was a easy approach in the Moose Lake trail but a challenging bushike with a lot of blowdonds and cliffs to summit Owl Pate......in a nice sunny day with a couple of black flies...

Thank You for this infornation.

Do you know which one of the Sawtooth mountains this is?

Only one of the Sawtooths is listed on the p50 list. Sawtooth #1, the highest peak in the Range, would have the greatest prominence of the range peaks. The prominence of Sawtooth #1 is determined from a relatively low col leading to a yet higher range (containing Seward). All of the lower Sawtooth Range mountains would have their prominence determined from higher cols with respect to Sawtooth #1. Thus they would have less prominence than Sawtooth #1. So Sawtooth #1 would be the peak on the p50 list.
