Organizing and summarizing search results for youThe Columbia River Gorge began forming as far back as the Miocene (roughly 17 to 12 million years ago). The Gorge’s formation began 40 to 60 million years ago, when molten lava pressure pushed up granite to frame the Columbia Basin. Between 6 to 17 million years ago, ancient volcanoes erupted, streaming more than 20 massive basalt flows into the area that’s now the Gorge. The Columbia River cut a deep canyon through the lava, ash and mud. The greatest force in the Gorge’s creation was flooding. About 15,000 years ago, near the end of the last Ice Age, gigantic floods up to 1,200 feet deep swept down the river corridor and scoured its cliffs, leaving its tributary streams hanging high above the river’s bed.3 Sources - See more
