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 California. 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. California generally follows this rule, especially the prominence part, as only 3 peaks on this list have under 2000' of prominence, one of them missing the cutoff by a mere 44 feet, all 3 being located in the Channel Islands. The rest, 2KPs and above, are scattered throughout the state.

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 California isolation list.
