Dune
A dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex. A large dune complex is called a dune field, while broad, flat regions covered with wind-swept sand or dunes with little or no vegetation are called ''ergs'' or ''sand seas''. Dunes occur in different shapes and sizes, but most kinds of dunes are longer on the stoss (upflow) side, where the sand is pushed up the dune, and have a shorter ''slip face'' in the lee side. The valley or trough between dunes is called a ''dune slack''. Dunes are most common in desert environments, where the lack of moisture hinders the growth of vegetation that would otherwise interfere with the development of dunes. However, sand deposits are not restricted to deserts, and dunes are also found along sea shores, along streams in semiarid climates, in areas of glacial outwash, and in other areas where poorly cemented sa ...

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] |
Rooster Rock State Park
Rooster Rock State Park is a state park located east of Corbett, in the U.S. state of Oregon. One of the features of the park is Rooster Rock, a column of basalt forming a natural obelisk, which stands near the south side of the Columbia River Gorge, in the lee of Crown Point. The park is administered by the Oregon Parks and Recreation Department. The monolith was mentioned in the journal of the explorers Lewis and Clark as their camping place on November 2, 1805. The name is phallic in origin, specifically, the column's original name was "Cock Rock". The Chinook word for the rock was ''iwash'', referring to penis. The name was later modified to Rooster Rock so as not to offend the public. The eastern portion of the park is designated as a clothing-optional beach, the first officially designated clothing-optional beach in the U.S. The only other clothing-optional beach in the state, after Glassbar Island's closing, is Collins Beach, on Sauvie Island in the Columbia River, nor ...

Sand Island (Clatsop County, Oregon)
Sand Island is an island in Baker Bay in the mouth of the Columbia River, located in Clatsop County, Oregon. It is situated north of Fort Stevens State Park and the Clatsop Spit, east of Cape Disappointment, and just south of Ilwaco, Washington. Sand Island is also the northernmost point in the state of Oregon. Sand Island is physically situated closer to the Washington mainland than to the Oregon mainland, although the border between the two states traverses the Columbia River north of the island. It often changes position in the river, and was described by Captain George Vancouver during his expedition but not by Lewis and Clark. The island was formerly subject to a border dispute between Oregon and Washington; Oregon won possession in a 1908 Supreme Court case, ''Washington v. Oregon''. According to an 1889 description in the ''Coast Pilot of California, Oregon, and Washington'': The island is covered in grass with a few small trees towards the center. East Sand Isla ...

Columbia River Gorge
The Columbia River Gorge is a canyon of the Columbia River in the Pacific Northwest of the United States. Up to deep, the canyon stretches for over as the river winds westward through the Cascade Range, forming the boundary between the state of Washington to the north and Oregon to the south. Extending roughly from the confluence of the Columbia with the Deschutes River (and the towns of Roosevelt, Washington, and Arlington, Oregon) in the east down to the eastern reaches of the Portland metropolitan area, the water gap furnishes the only navigable route through the Cascades and the only water connection between the Columbia Plateau and the Pacific Ocean. It is thus that the routes of Interstate 84, U.S. Route 30, Washington State Route 14, and railroad tracks on both sides run through the gorge. A popular recreational destination, the gorge holds federally protected status as the Columbia River Gorge National Scenic Area and is managed by the Columbia River Gorge Commi ...

Islands Of The Columbia River In Oregon
An island (or isle) is an isolated piece of habitat that is surrounded by a dramatically different habitat, such as water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental and oceanic. There are also artificial islands, which are man-made. Etymology The word ''island'' derives from Middle English ''iland'', from Old English ''igland'' (from ''ig'' or ''ieg'', similarly meaning 'island' when used independently, and -land carrying its contemporary meaning; cf. Dutch ''eiland'' ("island"), German ''Eiland'' ("small island")). However, the spelling of the word w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
