On December 29 my sons and I were in the Bay area and decided to pay a visit to Loma Prieta (CA prominence #30). Access was interesting. . . . We left SR 17...

I've compiled a list of parents and territories for the main British hills. To find the file (Excel), you can go to http://groups.yahoo.com/group/rhb/files/...

From Aaron's analysis of the Ben Nevis parentage is a most fascinating one indeed. If one rigorously sticks to using the prominence-based definition of a...
Adam, I totally agree! The list is the, how I call it "Prominence Master" - Lineage (excepted Elbrus, which is NOT on this line). Aaron's view of lineage makes...
Sorry, Adam, but you made another little error, Monte Rosa (Dufourspitze) is also excluded in the prominence master lineage, because it's prominence is only...
Adam, ... Eberhard, is right, Dufourspitze does not belong on the list (I transposed the prominence and saddle values.) Also Elbrus wouldn't be on the list....
Prominence folks---some of you may be interested to check out the list of the Top 25 peaks in the Alps as ranked by reduced spire measure. The table, with...

(Jonathan - private email) ... (Andy) Maybe all the Europe lists will be like Petter's 238 mountains in Norway with primary factors in the range 590 to 699...
Congratulations to David and Jonathan on an excellent list. The credibility of any list of mountains depends to some extent on its having familiar results...
The only part I played in this list was to supply some DEM data which I had already put together for prominence and panorama production. The list complements...
How about a single list, but with cutoffs of 2000ft for USA/Canada summits (where most maps are still non-metric) but 600m elsewhere? To declare a personal...
I have tended to stay out of the debate about prominence parents, because I do not think there are definitive answers. There will always be scope for argument,...
Dear Jonathan! The whole pass discription is wonderful! But please delete this words below. This was one of the reasons, why I left ExplorersWeb and they don't...

Well, I think, it's my turn to end this discussion satisfactory for everybody (I hope!). I am very sure, that at least the latter two "parents" are very useful...

I would certainly pick out Mount Massive as the visual parent of Elbert - as least as viewed from Leadville. If the visual parent concept were quantifiable,...
