Scappoose Bay
Scappoose Bay is a slough of Multnomah Channel, a distributary of the Willamette River, about upstream of where the channel meets the Columbia River in Columbia County, Oregon, United States. It is surrounded by a broad wetland area full of small ponds and other waterways across from Sauvie Island. It lies between Scappoose to the south and St. Helens to the north. A few small streams, including Milton Creek and Scappoose Creek drain from the east slopes of the Oregon Coast Range into the bay. Lying in the upper portion of the Columbia River Estuary, Scappoose Bay is tidal but is a freshwater body. The original inhabitants of the Scappoose Bay area were the Chinookan peoples who hunted, fished, and gathered in the area. During the 19th century, American settlers developed the area, clearing land for farming. Wood product manufacturing began in the early 20th Century. Three now-defunct factories left behind hazardous materials. Scappoose Bay is an important home for several ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sauvie Island
Sauvie Island, in the U.S. state of Oregon, originally Wapato Island or Wappatoo Island, is the largest island along the Columbia River, at , and one of the largest river islands in the United States. It lies approximately ten miles northwest of downtown Portland, between the Columbia River to the east, the Multnomah Channel to the west, and the Willamette River to the south. A large portion of the island is designated as the Sauvie Island Wildlife Area. Sturgeon Lake, in the north central part of the island, is the most prominent water feature. The land area is , or . Most of the island is in Multnomah County, but the northern third is in Columbia County. The Sauvie Island Bridge provides access across the Multnomah Channel from U.S. Route 30 and was completed in June 2008, replacing the first bridge to connect the island to the mainland which was opened on 30 December 1950. The island received the name "Sauvés Island" after Laurent Sauvé dit Laplante, a French-Canadian wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multnomah Channel
The Multnomah Channel is a distributary of the Willamette River. It diverges from the main stem a few miles upstream of the main stem's confluence with the Columbia River in Multnomah County in the U.S. state of Oregon. The channel flows northwest then north around Sauvie Island to meet the Columbia River near the city of St. Helens, in Columbia County. Chinook people, the Multnomahs, lived in villages along the channel at the time of European exploration of the Columbia River in the late 18th and early 19th centuries. Flanked in the 21st century by moorages, marinas, and parks, and populated by a wide variety of fish, the channel offers many opportunities for recreation. Course Constrained by dikes, the channel is about one-third as wide as the lower Willamette main stem.Williams, pp. 205–07 U.S. Route 30 and tracks of the Burlington Northern Railroad run roughly parallel to the channel, and to its left, between its source and the Multnomah–Columbia ...

Columbia County, Oregon
Columbia County is one of the 36 counties in the U.S. state of Oregon. As of the 2020 census, the population was 52,589. The county seat is St. Helens. History The Chinook and Clatskanie Native American peoples inhabited this region for centuries prior to the arrival of Robert Gray, captain of the ship ''Columbia Rediviva'', in 1792. The Lewis and Clark Expedition traveled and camped along the Columbia River shore in the area later known as Columbia County in late 1805 and again on their return journey in early 1806. Columbia County was created in 1854 from the northern half of Washington County. Milton served as the county seat until 1857 when it was moved to St. Helens. Columbia County has been afflicted by numerous flooding disasters, the most recent in December 2007. Heavy rains caused the Nehalem River to escape its banks and flood the city of Vernonia and rural areas nearby. Columbia County received a presidential disaster declaration for this event.

Milton Creek
Milton Creek, is a waterway in Columbia County, Oregon, United States. It is long, rising in the Oregon Coast Range and emptying into Scappoose Bay – a slough of Multnomah Channel – one of the distributaries of the Willamette River where it enters the Columbia River. The creek was named for a small settlement that was founded at the mouth of the creek in 1846, but later became Houlton because there was already a post office in Oregon with the name Milton ( Milton-Freewater). Houlton was later absorbed into St. Helens. The creek is home to several fish species, including steelhead trout, cutthroat trout, and coho salmon. Much of the undeveloped portion of the watershed is heavily forested. The upper reaches of Milton Creek receive around of precipitation a year, while the lower elevations closer to the Columbia River see closer to . Portions of Milton Creek have been significantly altered since permanent settlement came to the region for both farming and transporting log ...

Willamette River
The Willamette River ( ) is a major tributary of the Columbia River, accounting for 12 to 15 percent of the Columbia's flow. The Willamette's main stem is long, lying entirely in northwestern Oregon in the United States. Flowing northward between the Oregon Coast Range and the Cascade Range, the river and its tributaries form the Willamette Valley, a basin that contains two-thirds of Oregon's population, including the state capital, Salem, and the state's largest city, Portland, which surrounds the Willamette's mouth at the Columbia. Originally created by plate tectonics about 35 million years ago and subsequently altered by volcanism and erosion, the river's drainage basin was significantly modified by the Missoula Floods at the end of the most recent ice age. Humans began living in the watershed over 10,000 years ago. There were once many tribal villages along the lower river and in the area around its mouth on the Columbia. Indigenous peoples lived throughout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Columbia River
The Columbia River (Upper Chinook: ' or '; Sahaptin: ''Nch’i-Wàna'' or ''Nchi wana''; Sinixt dialect'' '') is the largest river in the Pacific Northwest region of North America. The river rises in the Rocky Mountains of British Columbia, Canada. It flows northwest and then south into the U.S. 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 fourth-largest river in the United States by volume, the Columbia has the greatest flow of any North American river entering the Pacific. The Columbia has the 36th greatest discharge of any river in the world. The Columbia and its tributaries have been central to the region's culture and economy for thousands of years. They have been used for transportation since a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oregon Coast Range
The Oregon Coast Range, often called simply the Coast Range and sometimes the Pacific Coast Range, is a mountain range, in the Pacific Coast Ranges physiographic region, in the U.S. state of Oregon along the Pacific Ocean. This north-south running range extends over from the Columbia River in the north on the border of Oregon and Washington, south to the middle fork of the Coquille River. It is wide and averages around in elevation above sea level. The coast range has three main sections, a Northern, Central, and Southern. The oldest portions of the range are over 60 million years old, with volcanics and a forearc basin as the primary mountain building processes responsible for the range. It is part of the larger grouping known as the Pacific Coast Ranges that extends over much of the western edge of North America from California to Alaska. The range creates a rain shadow effect for the Willamette Valley that lies to the east of the mountains, creating a more stable climate a ...

Columbia River Estuary
The Columbia River Estuary is situated on the Oregon–Washington border and the Pacific Coast of the United States. It was traditionally inhabited by the Chinook Native Americans and discovered by settlers in 1788. The Estuary plays host to a plethora of species of marine and terrestrial flora and fauna, and multiple conservation organisations exist that maintain the area. Geologically, it is situated on a continental margin of the North American Plate. The extent of the Columbia River Estuary Geographically, the Estuary of the Columbia River is defined as extending inland as far as the Bonneville Dam. It is the furthest point at which fluctuation of free-flowing water levels based on tide is substantial enough to be recorded. First Nation Peoples The Columbia River (Chinookan: ''hayásh-tsəqʷ'', meaning “great water”) was a bustling hub of trade for Native Americans in the Pacific Northwest for centuries.

Chinookan Peoples
Chinookan peoples include several groups of Indigenous people of the Pacific Northwest in the United States who speak the Chinookan languages. Since at least 4000 BCE Chinookan peoples have resided along the Lower and Middle Columbia River (Wimahl) (″Great River″) from the river's gorge (near the present town of The Dalles, Oregon) downstream (west) to the river's mouth, and along adjacent portions of the coasts, from Tillamook Head of present-day Oregon in the south, north to Willapa Bay in southwest Washington. In 1805 the Lewis and Clark Expedition encountered the Chinook Tribe on the lower Columbia. The term "Chinook" also has a wider meaning in reference to the Chinook Jargon, which is based on Chinookan languages, in part, and so the term "Chinookan" was coined by linguists to distinguish the older language from its offspring, Chinuk Wawa. There are several theories about where the name ″Chinook″ came from. Some say it is a Chehalis word ''Tsinúk'' for the inha ...

Sturgeon
Sturgeon is the common name for the 27 species of fish belonging to the family Acipenseridae. The earliest sturgeon fossils date to the Late Cretaceous The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the ..., and are descended from other, earlier Acipenseriformes, acipenseriform fish, which date back to the Early Jurassic period, some 174 to 201 million years ago. They are one of two living families of the Acipenseriformes alongside paddlefish (Polyodontidae). The family is grouped into four genera: ''Acipenser'' (which is paraphyletic, containing many distantly related sturgeon species), ''Huso'', ''Scaphirhynchus,'' and ''Pseudoscaphirhynchus''. Two species (''Adriatic sturgeon, A. naccarii'' and ''Dabry's sturgeon, A. dabryanus'') may be extinct in the wild, and one (''Syr Darya s ...
