Then.
12,000 to 15,000 years ago,--
The birth of the Willamette Valley.
Or, The true making of the Willamette Valley.
From here you can contemplate the natural forces that created the scene: Between 12,000 and 15,000 years ago, an ice age dam, holding back Glacial Lake Missoula, an inland sea, in Montana, collapsed, unleashing a cataclysmic flood that blasted through the Columbia River and Willamette valley's, known as the Ice Age Floods.

The first pictures of these floodwaters, are pictures #2, 3, and 4., the Ice Age Floods, and Glacial Lake Missoula.
...
The wall of water shaved off the sides of the valleys, tore away the lower slopes, and changed its cross-sectional profile from a V, to a U shape. It turned gentle slopes into sheer cliffs, and left the streams hanging high on the walls, to form the plunging waterfalls. It is widely believed, to be, the biggest floods ever, to occur on earth. Occurring perhaps as many as 50 to 100 times, over 2000 years!
When Glacial Lake Missoula burst, the Columbia River Gorge, was the narrowest constriction all along its route from Montana, where all 500 cubic miles of water were forced between these tall cliffs, only 1.5 miles apart. The flow accelerated from the narrow opening, reaching speeds of 80 miles an hour, before slowing and spreading out over the Portland Basin, and Willamette Valley, topping the valley, with 300 feet of water!
This painting, (PICTURE #2), gives a hint, of the awesome force, and volume, of the Ice Age Floods, originating from Glacial Lake Missoula, (picture #4).
The viewer’s vantage point is from the Chehalem Mountains, looking north towards Portland and the Columbia River.
It shows the first rush, of the Missoula Floods, coming into the upper North Willamette Valley, between the Cascade and Coastal range foothills.
At maximum flow, the largest of the floods filled the Willamette Valley, overtopping the Dundee and Eola-Amity hills.
The flood waters literally shook the ground as it thundered towards the Pacific Ocean and Willamette Valley.
The animals, (wholly mammoths and saber toothed tigers), and native peoples living here at that time, would have had about 30 minutes vibrational and sound warning, to reach high ground!
Vertebrate bones of thousands of late Pleistocene animals, including wholly mammoths, have been found in flood slackwater deposits. If they were around, people, would have been similarly inundated. But nothing has been found.
