Biddle Butte (Mount Zion) ...
|
Biddle Butte (also known as Mount Zion) is located in Skamania County, Washington, at Columbia River Mile (RM) _____, 2 miles west of Prindle and _____ miles east of Washougal. Upstream is located Beacon Rock.
The Butte was named for Henry J. Biddle, an early conservationist of the Gorge.
-
"... Biddle's main concern was for the preservation of Beacon Rock and the
Hamilton Mountain area, plus a nearby butte that became known as Biddle
Butte. He bought these properties prior to 1920, built trails and picnic
areas and maintained them all as public parks. He changed the name of the
huge monolith known at the time as Castle Rock back to Beacon Rock, as it
had been called by Lewis and Clark.
Biddle also succeeded in building a trail to the top of Beacon Rock, an
amazing engineering feat, finishing the task in 1918. This trail still is
enjoyed by thousands of hikers each year

Boring Lava Cone ...
Biddle Butte (Mount Zion) is a small olivine Boring Lava Field shield volcano that postdates the Troutdale Formation. A small basaltic-andesite intracanyon flow can be seen emanating from Biddle Butte. Biddle Butte lava caps the Cape Horn basalts. Similar Boring Lava vents in the Portland, Oregon, area are inferred to be less than 730,000 years old.
