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 25miles of isolation which are in the U.S. State of Oregon. 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. Oregon doesn't necessarily follow this rule, however, with 1 mountain as low as 2000' and several more less than 7000' in elevation, and 3 peaks with less than 2000' of prominence. It should be said that in these peaks' defense, they are, of course, a regional highpoint, or else they wouldn't be here.
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 Oregon isolation list.
|OR Rank||Peak Name||Isol. (Mi.)||Elev. (Ft.)||Prom. (Ft.)|
|12||Rock Creek Butte||43.4||9,106||4,466|
|27||Roman Nose Mountain||25.7||2,840||2,096|
