Age succeeds age, not always distinct, but often overlapping one another, and all changing the face of nature. The Coast Range rises, shutting in vast gulfs to fill later, and form the valleys of the Sacramento and San Joaquin in California and the Willamette in Oregon, with the partly filled basin of Puget Sound in Washington. Centering along the Cascade barrier, an era of terrific violence shakes the very foundation of the Northwest. Elevations and contours are changed. New lake beds are created. Watersheds and stream courses are remodeled. Dry "coulees" are left where formerly rivers flowed. Strata are uptilted and riven, to be cross-sectioned again by the new rivers as they cut new canyons in draining the new lakes. Most important of all, outflows of melted rock, pouring from fissures in the changing earth-folds, spread vast sheets of basalt, trap and andesite over most of the interior. Innumerable craters build cones of lava and scoriæ along the Cascade uptilt, and scatter clouds of volcanic ashes upon the steady sea winds, to blanket the country for hundreds of miles with deep layers of future soil.
A reign of ice follows the era of tropic heat. Stupendous glaciers grind the volcanic rocks, and carving new valleys, endow them with fertility for new forests that will rise where once the palm forests stood. With advancing age, the earth grows cold and quiet, awakening only to an occasional volcanic eruption or earthquake as a reminder of former violence. The dawn of history approaches. The country slowly takes on its present shape. Landscape changes are henceforth the work of milder forces, erosion by streams and remnant glaciers. Man appears.
