Hiking Beacon Rock
Beacon Rock is a monolithic remnant of a larger north-south lava dyke which forced its way through fissures to the surface some 50-60,000 years ago. It's location is significant in that it marked the end of of the now submerged Columbia Cascades, a series of dangerous rapids which began upstream at Cascade Locks; and it is the furthest point upstream where the oceans tidal influence can still be measured during periods of low stream flow.
The impressive engineered trail which zigzags its way to the top of Beacon Rock's 848 foot summit, gains 600 feet in elevation, and offers a two mile round trip hike.
The trail was built by Henry Biddle between 1915 and 1918, and was improved through a Civilian Conservation Core (CCC) project.
