Columbia 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 Com ...

Multnomah Falls
Multnomah Falls is a waterfall located on Multnomah Creek in the Columbia River Gorge, east of Troutdale, Oregon, Troutdale, between Corbett, Oregon, Corbett and Dodson, Oregon, Dodson, Oregon, United States. The waterfall is accessible from the Historic Columbia River Highway and Interstate 84 in Oregon, Interstate 84. Spanning two tiers on basalt cliffs, it is the tallest waterfall in the state of Oregon at in height. The Multnomah Creek Bridge, built in 1914, crosses below the falls, and is listed on the National Register of Historic Places. The land surrounding the falls was developed by Simon Benson in the early-twentieth century, with a pathway, viewing bridge, and adjacent lodge being constructed in 1925. The Multnomah Falls Lodge and the surrounding footpaths at the falls were added to the National Register of Historic Places in 1981. Contemporarily, the state of Oregon maintains a switchback trail that ascends to a scree, talus slope above the falls, and descends to an ...

Interstate 84 (Oregon–Utah)
Interstate 84 (I-84) is an Interstate Highway in the northwestern United States. The highway runs almost 770 miles (1239 km) from Portland, Oregon, to a junction with I-80 near Echo, Utah. The highway serves and connects Portland, Boise, and Ogden, Utah. With connections to other highways, I-84 connects these cities to points east and also serves as part of a corridor between Seattle and Salt Lake City. The sections running through Oregon and Idaho are also known as the Vietnam Veterans Memorial Highway."" The highway originally served as a fork of I-80 to serve the Pacific Northwest, and was originally numbered Interstate 80N. It was generally built along the corridor of U.S. Route 30 (US 30) and US 30S, which themselves largely followed the Oregon Trail; the US 30S designation was decommissioned in the 1970s after the freeway replacement was mostly complete. The highway was signed with the I-84 designation in 1980, when a 1977 change in guidelines took effec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridal Veil Falls, October 2020
A bride is a woman who is about to be married or who is a newlywed. When marrying, if the bride's future spouse is a man, he is usually referred to as the ''bridegroom'' or just ''groom''. In Western culture, a bride may be attended by a maid, bridesman and one or more bridesmaids. The word "bride" has its roots in the Old English word ''bryd'', which is shared with other Germanic languages. In Western countries, brides typically wear white wedding dresses, a tradition started by Queen Victoria. The white dress was once considered a symbol of luxury due to the difficulties in laundering delicate white clothing. Today, Western brides may wear white, cream, or ivory dresses, regardless of their number of marriages. In non-Western countries, brides often wear national dress, with white wedding dresses being uncommon in Asian cultures as it symbolizes mourning and death. Red, on the other hand, represents vibrancy and health and is commonly worn by brides in many Asian cultures. Br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or bec ...

Micro-habitats
In ecology, habitat refers to the array of resources, biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species' habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior of a stem, a rotten log, a ...

Temperate Rain Forest
Temperate rainforests are rainforests with coniferous or broadleaf forests that occur in the temperate zone and receive heavy rain. Temperate rainforests occur in oceanic moist regions around the world: the Pacific temperate rainforests of North American Pacific Northwest as well as the Appalachian temperate rainforest in the Appalachian region of the United States; the Valdivian temperate rainforests of southwestern South America; the rainforests of New Zealand and southeastern Australia; northwest Europe (small pockets in Great Britain and larger areas in Ireland, southern Norway, northern Iberia and Brittany); southern Japan; the Black Sea–Caspian Sea region from the southeasternmost coastal zone of the Bulgarian coast, through Turkey, to Georgia, and northern Iran. The moist conditions of temperate rainforests generally have an understory of mosses, ferns and some shrubs and berries. Temperate rainforests can be temperate coniferous forests or temperate broadleaf and mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecosystem
An ecosystem (or ecological system) is a system formed by Organism, organisms in interaction with their Biophysical environment, environment. The Biotic material, biotic and abiotic components are linked together through nutrient cycles and energy flows. Ecosystems are controlled by external and internal Environmental factor, factors. External factors—including climate—control the ecosystem's structure, but are not influenced by it. By contrast, internal factors control and are controlled by ecosystem processes; these include decomposition, the types of species present, root competition, shading, disturbance, and succession. While external factors generally determine which Resource (biology), resource inputs an ecosystem has, their availability within the ecosystem is controlled by internal factors. Ecosystems are wikt:dynamic, dynamic, subject to periodic disturbances and always in the process of recovering from past disturbances. The tendency of an ecosystem to remain clo ...
