relief (Patreon)

"Although the peaks of the North Cascades do not reach great elevations (high peaks are generally in the 2,100 to 2,400 m (7,000 to 8,000 ft) range, their overall relief, the relatively uninterrupted vertical distance from valley bottom to mountain top, is commonly 1,200 to 1,800 m (4,000 to 6,000 ft)."

One really cool fact from an overall fascinating wikipedia article I found today on geology in the PNW.
