Information:  - 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 Rocky Mountains 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 far northern California and east to the Continental Divide, thus including Idaho, Western Montana, and western Wyoming. 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.  - In geography, a confluence is the meeting of two or more bodies of water. Also known as a "conflux", it refers either to the point where a tributary joins a larger river, (main stem), or where two streams meet to become the source of a river of a new name, such as the confluence of the Monongahela and Allegheny rivers in Pittsburgh, Pennsylvania creating the Ohio River.  - Portland is a seaport and the largest city in the U.S. state of Oregon and the seat of Multnomah County. It is in the Willamette Valley region of the Pacific Northwest, at the confluence of the Willamette and Columbia Rivers. The city covers and had an estimated population of 632,309 in 2015, making it the 26th most populous city in the United States. Approximately 2,389,228 people live in the Portland metropolitan statistical area (MSA), the 23rd most populous MSA in the United States. Its Combined Statistical Area (CSA) ranks 17th with a population of 3,022,178. Roughly 60% of Oregon's population resides within the Portland metropolitan area.  - A combined statistical area (CSA) is composed of adjacent metropolitan (MSA) and micropolitan statistical areas (µSA) in the United States and Puerto Rico that can demonstrate economic or social linkage. The United States Office of Management and Budget defines a CSA as consisting of various combinations of adjacent metropolitan and micropolitan areas with economic ties measured by commuting patterns. These areas that combine retain their own designations as metropolitan or micropolitan statistical areas within the larger combined statistical area.  - Carson Friedman Ellis ( born October 5 , 1975 ) is an artist living in Portland , Oregon .

The river rises in the Rocky Mountains of British Columbia, Canada. It flows northwest and then south into the US state of Washington, then turns west to form most of the border between Washington and the state of Oregon before emptying into the Pacific Ocean. The river is long, and its largest tributary is the Snake River. Its drainage basin is roughly the size of France and extends into seven US states and a Canadian province.  - The Portland metropolitan area or Greater Portland is a metropolitan area in the U.S. states of Oregon and Washington centered on the principal city of Portland, Oregon. The U.S. Office of Management and Budget identifies it as the PortlandVancouverHillsboro, ORWA Metropolitan Statistical Area, a metropolitan statistical area used by the United States Census Bureau and other entities. The OMB defines the area as comprising Clackamas, Columbia, Multnomah, Washington, and Yamhill Counties in Oregon, and Clark and Skamania Counties in Washington. The area's population is estimated at 2,348,247 in 2014.  - A U.S. state is a constituent political entity of the United States of America. There are 50 states, which are bound together in a union with each other. Each state holds administrative jurisdiction over a defined geographic territory, and shares its sovereignty with the United States federal government. Due to the shared sovereignty between each state and the federal government, Americans are citizens of both the federal republic and of the state in which they reside. State citizenship and residency are flexible, and no government approval is required to move between states, except for persons covered by certain types of court orders (e.g., paroled convicts and children of divorced spouses who are sharing custody).
