List "North Cascades National Park Peaks [Clean P400s]" By EricNoel
Notes: This is a list of all summits with 400 feet of clean prominence in North Cascades National Park. The one exception is that I have listed both "X Mountain" and Trappers Peak. By clean prominence standards Trappers is the peak and by mean prom standards X Mountain is the peak instead. So I've listed both. Thanks to John Roper who worked on a project related to this list with me several years ago.
