Willapa Hills: The Willapa Hills is a geologic, physiographic, and geographic region in southwest Washington.  When described as a physiographical province, the Willapa Hills are bounded by the Pacific Ocean to the west, the Columbia River to the south, the Olympic Mountains to the north, and the Cascade Range to the east.  Some definitions place the Puget Lowland physiographic province east of the Willapa Hills.  Included within the province are the Black Hills, the Doty Hills, and a number of broad river valleys, some of which open up into broad estuaries on the Pacific such as Grays Harbor and Willapa Bay.  Other definitions do not include the Black Hills.  The USGS GNIS defines the Willapa Hills as bounded by the Columbia River to the south and the Chehalis River to the north, without giving specific east and west bounds.  The Willapa Hills are one of the Pacific Coast Ranges, which continue north as the Olympic Mountains and south, across the Columbia River, as the Oregon Coast Range.

Pacific Northwest: The Pacific Northwest (in the United States, commonly abbreviated as PNW), sometimes referred to as Cascadia, is a geographic region in western North America bounded by the Pacific Ocean to the west and (loosely) by the Cascade Mountain Range on the east.  Though no agreed boundary exists, a common conception includes the U.S. states of Oregon and Washington and the Canadian province of British Columbia.  Broader conceptions reach north into Alaska and Yukon, south into northern California and east to the Continental Divide, thus including Idaho, Western Montana, and western Wyoming.  Idaho, Wyoming, and Montana are more accurately termed the Inland Northwest (INW), as the climate, folia, fauna, and politics are different than in the Pacific Northwest, as well as a different time zone in all but North Idaho.  Narrower conceptions may be limited to the northwestern US or to the coastal areas west of the Cascade and Coast mountains.  The variety of definitions can be attributed to partially overlapping commonalities of the region's history, geography, society, and other factors.
