Oregon's Most Prominent Peaks

Mount Jefferson from the Whitewater Trail

The topographic prominence of a peak is the height of the peak's summit as the vertical distance between it and the lowest contour line encircling it but containing no higher summit within it. It is a measure of the independence of a peak, how significantly it stands apart from neighboring peaks.

The topographic isolation of a peak is the minimum great-circle distance from the peak's summit to a point of equal elevation. Topographic isolation represents a radius of dominance in which the peak is the highest point. Between the two measures I think topographic prominence is a more reliable measure of the perceived significance of a peak.

The map below shows the locations of the 198 peaks in Oregon with at least 1400 feet of prominence. Most of these peaks are listed below, organized by region and sorted within region by prominence. To these I have added other Oregon peaks I have visited with at least 1000 feet of prominence.

Visiting these peaks has been an excellent way for me to explore my home state.
