Biddle Butte

From Oregon Hikers Field Guide

View to Biddle Butte (Mount Zion) from the Cape Horn Trail (bobcat)


Biddle Butte, also known as Mount Zion, is a member of the Boring Lava Field and thus kin to the many small volcanoes in the Portland/Camas/Washougal area as well as the west Columbia River Gorge. It is far younger than the Columbia River Basalt layers that it caps, perhaps by about 14 million years! Biddle Butte is the highest prominence on the Cape Horn upland, but there are communications towers on the summit. The forest land surrounding the summit is part of the Gifford Pinchot National Forest.

Henry J. Biddle was an early Gorge advocate who is responsible for preserving Beacon Rock and building the walkway to the top. The volcano was officially named Biddle Butte in 1989.
