Inscription.
There is much of legend and tradition associated with the Columbia River and its gorge. The geologic story is neither fable, myth nor tradition, but one of fact, facts that independently stand out in every rock and waterfall, as if begging for recognition.
Ira A. Williams
Geologist, 1916

Geologists tell us the Cascade Range formed 35 million years ago as plates of the Earth's crust collided. Then, 20 million years ago, molten basalt gushing from cracks near the Idaho border covered 80,000 square miles and shifted the Columbia River north to its present location.

During the last Ice Age, melting ice dams in Montana released massive floods that scoured this canyon perhaps 100 times – waters so high, they surged over the top of Crown Point. Helped by these floods, the Columbia cut through layers of stone faster than her smaller tributaries, creating the greatest concentration of high waterfalls in North America. Lava no longer flows to laminate this landscape, and the Ice Age is long past, but the Gorge remains dynamic. Landslides continue to move mountains, and tiny crystalline droplets caught by winter's freeze, crack the cliffs etching another season into the Columbia's Gorge.

3. Marker detail: Ice Age Floods
The first Ice Age floods were the largest and dirtiest. Carrying rock-laden icebergs and vast amounts of debris, these floods scoured the landscape of vegetation and removed up to 150 feet of topsoil. Floodwaters surged nearly 1,000 feet deep through the Gorge, and farther west they spread out to cover the Portland Basin with 400 feet of water.
foot (600 meters) high ice dam blocked the river, creating a lake that stretched for hundreds of miles. The water drained out of the lake in two or three days, flooding eastern Washington. The flood, moving up to sixty miles per hour, scoured out hundreds of miles of canyons called coulees, created the largest waterfall to ever exist, and left 300 foot high gravel bars. During a period of 2,500 years as many as 100 of these floods scoured the Gorge. (Submitted on February 13, 2018, by Cosmos Mariner of Cape Canaveral, Florida.)
