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 ...

Sauvie Island Bridge
The Sauvie Island Bridge crosses the Multnomah Channel of the Willamette River near Portland, Oregon, United States. The original Parker truss bridge, built in 1950 with a main span, was replaced with a tied arch bridge with a span in 2008 due to cracks discovered in 2001. In November 2022, the Multnomah County Board of Commissioners voted to rename the bridge (to a yet-to-be-determined name) in honor of the Native Americans that originally lived on Sauvie Island. Old bridge Opened on December 30, 1950, the first bridge to Sauvie Island replaced the Sauvie Island Ferry. The $900,000 bridge was designed by the Oregon Department of Transportation and built by Gilpin Construction. Oregon transferred ownership to Multnomah County in 1951. Composed of three steel truss spans, it was a total of long, with the main span measuring in length. The approach spans were built of reinforced concrete girders. Green in color, the bridge was wide and carried two lanes of traffic and had sidewa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Left Bank
In geography, a bank is the land alongside a body of water. Different structures are referred to as ''banks'' in different fields of geography, as follows. In limnology (the study of inland waters), a stream bank or river bank is the terrain alongside the bed of a river, creek, or stream. The bank consists of the sides of the channel, between which the flow is confined. Stream banks are of particular interest in fluvial geography, which studies the processes associated with rivers and streams and the deposits and landforms created by them. Bankfull discharge is a discharge great enough to fill the channel and overtop the banks. The descriptive terms ''left bank'' and ''right bank'' refer to the perspective of an observer looking downstream; a well-known example of this being the sections of Paris as defined by the river Seine. The shoreline of ponds, swamps, estuaries, reservoirs, or lakes are also of interest in limnology and are sometimes referred to as banks. The grade ...

Longhouses Of The Indigenous Peoples Of North America
Longhouses were a style of residential dwelling built by Native American First Nation peoples in various parts of North America. Sometimes separate longhouses were built for community meetings. Iroquois and the other East Coast longhouses The Iroquois (Haudenosaunee or "People of the Longhouses") who resided in the Northeastern United States as well as Eastern Canada (Ontario and Quebec) built and inhabited longhouses. These were sometimes more than in length but generally around wide. Scholars believe walls were made of sharpened and fire-hardened poles (up to 1,000 saplings for a house) driven close together into the ground. Strips of bark were woven horizontally through the lines of poles to form more or less weatherproof walls. Poles were set in the ground and braced by horizontal poles along the walls. The roof is made by bending a series of poles, resulting in an arc-shaped roof. This was covered with leaves and grasses. The frame is covered by bark that is sewn in place ...

Charles Wilkes
Charles Wilkes (April 3, 1798 – February 8, 1877) was an American naval officer, ship's captain, and explorer. He led the United States Exploring Expedition (1838–1842). During the American Civil War (1861–1865), he commanded ' during the Trent Affair in which he stopped a Royal Mail ship and removed two Confederate diplomats, which almost led to war between the United States and the United Kingdom.

Lewis And Clark Expedition
The Lewis and Clark Expedition, also known as the Corps of Discovery Expedition, was the United States expedition to cross the newly acquired western portion of the country after the Louisiana Purchase. The Corps of Discovery was a select group of U.S. Army and civilian volunteers under the command of Captain Meriwether Lewis and his close friend Second Lieutenant William Clark. Clark and 30 members set out from Camp Dubois, Illinois, on May 14, 1804, met Lewis and ten other members of the group in St. Charles, Missouri, then went up the Missouri River. The expedition crossed the Continental Divide of the Americas near the Lemhi Pass, eventually coming to the Columbia River, and the Pacific Ocean in 1805. The return voyage began on March 23, 1806, at Fort Clatsop, Oregon, and ended on September 23 of the same year. President Thomas Jefferson commissioned the expedition shortly after the Louisiana Purchase in 1803 to explore and to map the newly acquired territory, to find a pr ...

United States Board On Geographic Names
The United States Board on Geographic Names (BGN) is a federal body operating under the United States Secretary of the Interior. The purpose of the board is to establish and maintain uniform usage of geographic names throughout the federal government of the United States. History On January 8, 1890, Thomas Corwin Mendenhall, superintendent of the US Coast and Geodetic Survey Office, wrote to 10 noted geographers "to suggest the organization of a Board made up of representatives from the different Government services interested, to which may be referred any disputed question of geographical orthography." President Benjamin Harrison signed executive order 28 on September 4, 1890, establishing the ''Board on Geographical Names''. "To this Board shall be referred all unsettled questions concerning geographic names. The decisions of the Board are to be accepted y federal departmentsas the standard authority for such matters." The board was given authority to resolve all unsettled ques ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louse Island
Louse ( : lice) is the common name for any member of the clade Phthiraptera, which contains nearly 5,000 species of wingless parasitic insects. Phthiraptera has variously been recognized as an order, infraorder, or a parvorder, as a result of developments in phylogenetic research. Lice are obligate parasites, living externally on warm-blooded hosts which include every species of bird and mammal, except for monotremes, pangolins, and bats. Lice are vectors of diseases such as typhus. Chewing lice live among the hairs or feathers of their host and feed on skin and debris, while sucking lice pierce the host's skin and feed on blood and other secretions. They usually spend their whole life on a single host, cementing their eggs, called nits, to hairs or feathers. The eggs hatch into nymphs, which moult three times before becoming fully grown, a process that takes about four weeks. Genetic evidence indicates that lice are a highly modified lineage of Psocoptera (now called Psocod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
