Willamette Valley Geologic Province

The Willamette Valley province forms a catch basin between the Coast Range and the Cascades. The sediments collected in it record multiple Ice Age floods that originated in Montana, poured through the Cascades (via the Columbia River) and backed up here in the valley before eventually draining to the Pacific Ocean.
