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 U.S. State of Idaho. 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. Idaho is no exception as the state's highest and most prominent peak is also its most isolated, and, indeed, all of the peaks on this list but one--and even that is an Error Range peak--are also on the Idaho 2KPs page, and none are under 7000' in height.

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 Idaho isolation list.
