| Beacon Rock (located on the Washington side of the river) is a prominent landmark along the Columbia River just downstream of the Bonnieville Dam on the Columbia River. Beacon Rock was named by Clark on November 2, 1805. It was here that the expedition crew first observed Pacific Ocean tidewater.For more information on Beacon rock see http://vulcan.wr.usgs.gov/Volcanoes/Washington/BeaconRock/description_beacon_rock.html. |
