It spread much more rapidly than hunting and gathering did so many generations before, but essentially followed the same pattern: sweeping into Europe and North Africa, leaving out only
the western edges of both continents about 200 generations ago.
Journeying down the Pacific Northwest coast, tracing the ragged line
of the
continent's
western edge, you encounter some
of the most spectacular scenery anywhere in the U.S.. From the forested shores
of Washington, to Oregon's rugged coastal mountains, to the cliff - lined coves
of northern California, there's a whole world
of untamed beauty here.
