Local relief and the height of Mount Olympus

Auteurs :

Description :
A three-dimensional assessment of the net volume of rock differentially eroded from below mountain tops to form valleys yields a range-wide constraint on feedback between valley development and the height of mountain peaks. The superelevation of mountain peaks potentially attributable to differential removal of material from below peaks in the Olympic Mountains, Washington, was constrained by fitting a smoothed surface to the highest elevation points on a 30 m grid digital elevation model of the range. It therefore appears that the location of the highest peak in the Olympics is controlled by the deep valleys excavated in the centre of the range.
