That’s not The Columbia River Gorge then I think. It’s like, the Columbia River, in a gorge. The Columbia River Gorge is between Portland and Kennewick area specifically. Not that it really matters.
The geology out there is pretty amazing. Giant fucking lava flows covered everything millions of years ago and then there were cataclysmic ice age floods that carved out the gorges and whatnot. The Columbia river carried something like 13 times the volume of the Amazon River at times during the floods.
