What is the 25-Mile Isolation List?

Just as 2000' is an important prominence threshold and 14000' an important elevation threshold, 25 miles is the magic number that gives a peak a spot on an isolation list. This page contains those peaks with 25 miles of isolation which are in the northeastern United States. But what is isolation anyway? Isolation is how far a peak is from the nearest higher one. Understandably, isolated peaks are often also high in elevation, are very topographically prominent, or, in some cases, both. This is the eastern U.S., keep in mind, so the highest thing there is is Mount Washington, NH, however the peaks are generally speaking very important for eastern peakbagging. 

Contained below is a table containing the peak's name--which has a hyperlink to the peak page--as well as its isolation, elevation, and topographical prominence. So, without further ado, the NE U.S. isolation list.

Mount Davis, PA

It is worth mentioning that Mount Davis, PA, might well belong on this list, Peakbagger gives it 24.99 mi. of isolation. There may be other peaks like this, in the "Error Range," all of which warrant further research. If anyone has any conclusive data, please let me know ASAP, because the total would then go up from 43 to 44, making this list inaccurate.

Mount Ellen or Camel's Hump?

It is uncertain whether Ellen or Camel's Hump is higher, so if anyone has anything conclusive one way or the other, please let me know ASAP, because if Camel's Hump is truly higher, then Mount Ellen does not have 25 miles of isolation, taking the total down from 43 to 42, making this list inaccurate.

Additions & Corrections

If there are any errors--which there may well be, as I have never lived in the Northeast--feel free to contact me.
