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.

Illinois County, Virginia: Illinois County, Virginia, was a political and geographic region, part of the British Province of Quebec, claimed during the American Revolutionary War on July 4, 1778 by George Rogers Clark of the Virginia Militia, during the Illinois Campaign.  It was formally recognized by the Commonwealth of Virginia later that year.  The County was accorded official governmental existence, including legally defined boundaries and a formal governmental structure under the laws of the Commonwealth.  The county seat was the old French village of Kaskaskia.  John Todd was appointed by Governor Patrick Henry to head the county's government.  The county's existence also has a defined end-point in 1784, when the Commonwealth of Virginia ceded the land to the new United States federal government.  The area later became part of the Northwest Territory by an Act of Congress in 1787.  The county was bordered to the southeast by the Ohio River at the time of its existence.  It is not within the boundaries of the modern-day state of Virginia.

Mormonism in the Pacific Northwest: Mormonism has had a long history in the Pacific Northwest of the United States.  Mormons have had a large influence on the region's development, as they settled throughout the states of Idaho, Oregon, and Washington, and took part in the construction of the region's early infrastructure, as well as worked in the lumber mills and mines across these states.  Today, despite a period of discrimination based on their religious affiliation, the region boasts a relatively large population of Church of Latter-Day Saints members compared to other parts of the United States outside of Utah.
