Historical Marker
Beacon Rock
Multnomah County · Oregon
The rock stands across the river in Washington; this board is on the Oregon bank at the Bonneville Fish Hatchery. Lewis and Clark named it in 1805. Early in the twentieth century the Army Corps of Engineers began tunneling into it, meaning to break it up for jetty stone at the Columbia's mouth. Henry Biddle bought it in 1915 for a dollar and built the trail to the top. After his death his children offered it to Washington, which turned the gift down. Oregon's parks engineer, Sam Boardman, offered to accept it instead, and Washington took it in 1935.
What the plaque says
Oregon History Beacon Rock Beacon Rock is a monolith, the core of a young volcano that erupted around 57,000 years ago. It is claimed to be the second largest freestanding monolith in the world. Lewis and Clark named it Beacon Rock in 1805. Native peoples and Lewis and Clark recognized that Beacon Rock marked the last of the rapids on the Columbia River and the beginning of tidal influence from the Pacific Ocean, 150 miles away. Henry J. Biddle, a prominent botanist, geologist, and engineer, purchased Beacon Rock in 1915 for $1 and built a trail to the top in 1916-1918, an engineering marvel at the time with handrails, bridges, and 51 switchbacks. Washington State established Beacon Rock as a park in 1935.
