Scenic View/Photo Spot
Outside Skamania, Washington is the 848 foot-tall Beacon Rock that overlooks a breathtaking section of the mighty Columbia River. Beacon Rock State Park is a 4,464-acre, year-round camping park sitting in the midst of the Columbia Gorge National Scenic Area.
The core of an ancient volcano, Beacon Rock is essentially a basalt plug; the Missoula Flood waters eroded away the softer outer material.
The Lewis and Clark Expedition visited this location on October 31, 1805. Clark described,
"a remarkable high detached rock Stands in a bottom on the Stard Side near the lower point of this Island on the Stard. Side about 800 feet high and 400 paces around, we call the Beaten rock."
Significantly, Clark also noted the first evidence of tidewater:
“I could not See any rapids below in the extent of my view which was for a long distance down the river, which from the last rapids widened and had everry appearance of being effected by the tide.”
The expedition revisited Beacon Rock returning upriver on April 6, 1806. Lewis wrote,
“from the appearance of a rock […] I could judge better of the rise of the water than I could at any point below. I think the flood of this spring has been about 12 feet higher than it was [the previous fall]; the river is here about 1½ miles wide; it’s general width from the beacon rock which may be esteemed the head of tide water, to the marshey islands is from one to 2 miles tho’ in many places it is still wider. it is only in the fall of the year when the river is low that the tides are persceptable as high as the beacon rock. this remarkable rock which stands on the North shore of the river is unconnected with the hills and rises to the hight of seven hundred feet; […] it rises to a very sharp point and is visible for 20 miles below on the river.”
As the area was settled in the 19th century, the basalt feature was given a variety of names, including Castle Rock. By 1915, river developments threatened to destroy the rock. Henry J. Biddle, a prominent Washingtonian and descendant of Nicholas Biddle, the original editor of Lewis and Clark's journals, purchased it and constructed a trail to the top. He eventually donated it to the state, and in 1935 the landmark was designated a state park under the original name given by Clark.
