The Columbia River Gorge is the same age as the Cascades and much older than the glacial floods. The Columbia river is older than the mountains and the Gorge formed as the mountains rose.
The Gorge looked different before the glacial floods, they definitely change it. But the floods took that path to the sea because the Gorge was there. The floods had more effect on the Willamette Valley where they dumped lots of debris into the valley.
- mlhpdx 3y agoI’d quibble that the Cascades don’t have an age as they have continually been destroyed and renewed. They started at some point and have never stopped. What I mean by “the gorge” is what is monumental. The river was there, but what we admire about it is much more recent. Also, I’m not trying to be precise. The article was fundamentally about fear, and I’m just speaking to all the natural things around me that can cause it but really shouldn’t.
