To determine the 100 highest mountains in Washington, an initial list was generated using available maps that contained the summits with 400 feet or more of clean prominence. Clean prominence is defined as the number of feet a peak rises above the lowest contour that entirely encircles the peak without including any others. The following adjustments were then made to this list:

• Volcanic subpeaks were removed from the list so that each volcano (apart from Mount Rainier) has one summit on the list.
• Little Tahoma was included in the list because of its impressive size and prominence even on a peak as large as Mount Rainier.
• Seven Fingered Jack and Blackcap Mountain were included in the list because their clean prominence was within the margin of error (+39 feet) for the calculation.

This methodology produced a wonderfully varied and interesting list of peaks that includes all of the major summits of Washington. (For those of you pursuing the Bulger Top 100, see the minor differences between the lists here.)

We are currently working to get a nice picture of each peak up on the website, linked-to from the peak name. It will take us a while to complete this. If you have a picture that you'd like to contribute, please email Scott at scott@summitroutes.com.
