Bridge Of The Gods (land Bridge)
The Bridge of the Gods was a natural dam created by the Bonneville Slide, a major landslide that dammed the Columbia River near present-day Cascade Locks, Oregon in the Pacific Northwest of the United States. The river eventually breached the bridge and washed much of it away, but the event is remembered in local legends of the Native Americans as the ''Bridge of the Gods''. The Bridge of the Gods is also the name of a modern manmade bridge, across the Columbia River between Oregon and Washington. Geologic history Interpretations of the age of the Bonneville landslide have evolved as more investigators have studied it and as more modern dating techniques have become available. Early work based on dendrochronology and radiocarbon dating suggested the landslide occurred between AD 1060 and 1180 or between 1250 and 1280. The year 1100 has often been cited as the date of the Bonneville landslide. More recent work using radiocarbon dating and lichenometry has suggested d ...

Landslide
Landslides, also known as landslips, are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, deep-seated grade (slope), slope failures, mudflows, and debris flows. Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or even underwater, in which case they are called submarine landslides. Gravity is the primary driving force for a landslide to occur, but there are other factors affecting slope stability that produce specific conditions that make a slope prone to failure. In many cases, the landslide is triggered by a specific event (such as a heavy rainfall, an earthquake, a slope cut to build a road, and many others), although this is not always identifiable. Causes Landslides occur when the slope (or a portion of it) undergoes some processes that change its condition from stable to unstable. This is essentially due to a decrease in the She ...

1700 Cascadia Earthquake
The 1700 Cascadia earthquake occurred along the Cascadia subduction zone on January 26, 1700, with an estimated moment magnitude of 8.7–9.2. The megathrust earthquake involved the Juan de Fuca Plate from mid-Vancouver Island, south along the Pacific Northwest coast as far as northern California. The length of the fault rupture was about , with an average slip of . The earthquake caused a tsunami which struck the west coast of North America and the coast of Japan. Japanese tsunami records, along with reconstructions of the wave moving across the ocean, put the earthquake at about 9pm on the evening of 26 January 1700. Evidence The earthquake took place at about 21:00 Pacific Time on January 26, 1700 ( NS). Although there are no written records for the region from the time, the timing of the earthquake has been inferred from Japanese records of a tsunami that does not correlate with any other Pacific Rim quake. The Japanese records exist primarily in the modern-day Iwate Pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Hood
Mount Hood is a potentially active stratovolcano in the Cascade Volcanic Arc. It was formed by a subduction zone on the Pacific coast and rests in the Pacific Northwest region of the United States. It is located about east-southeast of Portland, on the border between Clackamas and Hood River counties. In addition to being Oregon's highest mountain, it is one of the loftiest mountains in the nation based on its prominence, and it offers the only year-round lift-served skiing in North America. The height assigned to Mount Hood's snow-covered peak has varied over its history. Modern sources point to three different heights: , a 1991 adjustment of a 1986 measurement by the U.S. National Geodetic Survey (NGS), based on a 1993 scientific expedition, and of slightly older origin. The peak is home to 12 named glaciers and snowfields. It is the highest point in Oregon and the fourth highest in the Cascade Range. Mount Hood is considered the Oregon volcano most likely to erupt, thoug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Dalles, Oregon
The Dalles is the largest city of Wasco County, Oregon, United States. The population was 16,010 at the 2020 census, and it is the largest city on the Oregon side of the Columbia River between the Portland Metropolitan Area, and Hermiston. History The site of what is now the city of The Dalles was a major Native American trading center. The general area is one of the continent's most significant archaeological regions. Lewis and Clark camped near Mill Creek on October 25–27, 1805, and recorded the Indian name for the creek as ''Quenett''. Etymology The name of the city comes from the French word ''dalle'', meaning either "sluice", akin to English "dale" and German ''T'' 'h'''al'', "valley", or "flagstone", referring to the columnar basalt rocks carved by the river (in ''voyageur'' French used to refer to rapids), which was used by the French-Canadian employees of the North West Company to refer to the rapids of the Columbia River between the present-day city and Celilo ...

Klickitat Tribe
The Klickitat (also spelled Klikitat) are a Native Americans in the United States, Native American tribe of the Pacific Northwest. Today most Klickitat are enrolled in the Federally recognized tribe, federally recognized Confederated Tribes and Bands of the Yakama Nation, some are also part of the Confederated Tribes of the Grand Ronde Community of Oregon. A Sahaptian languages, Shahaptian tribe, their eastern neighbors were the Yakama, who speak a closely related language. Their western neighbors were various Salishan and Chinookan tribes. Their name has been perpetuated in Klickitat County, Washington, Klickitat, Washington, Klickitat Street in Portland, Oregon (also Big Lake, Minnesota), and the Klickitat River, a tributary of the Columbia River. The Klickitat were noted for being active and enterprising traders, and served as intermediaries between the coastal tribes and those living east of the Cascade Mountains.

Cascade Volcanoes
The Cascade Volcanoes (also known as the Cascade Volcanic Arc or the Cascade Arc) are a number of volcanoes in a volcanic arc in western North America, extending from southwestern British Columbia through Washington and Oregon to Northern California, a distance of well over . The arc formed due to subduction along the Cascadia subduction zone. Although taking its name from the Cascade Range, this term is a geologic grouping rather than a geographic one, and the Cascade Volcanoes extend north into the Coast Mountains, past the Fraser River which is the northward limit of the Cascade Range proper. Some of the major cities along the length of the arc include Portland, Seattle, and Vancouver, and the population in the region exceeds 10 million. All could be potentially affected by volcanic activity and great subduction-zone earthquakes along the arc. Because the population of the Pacific Northwest is rapidly increasing, the Cascade volcanoes are some of the most dangerous, due to th ...

Folklore
Folklore is shared by a particular group of people; it encompasses the traditions common to that culture, subculture or group. This includes oral traditions such as tales, legends, proverbs and jokes. They include material culture, ranging from traditional building styles common to the group. Folklore also includes customary lore, taking actions for folk beliefs, the forms and rituals of celebrations such as Christmas and weddings, folk dances and initiation rites. Each one of these, either singly or in combination, is considered a folklore artifact or traditional cultural expression. Just as essential as the form, folklore also encompasses the transmission of these artifacts from one region to another or from one generation to the next. Folklore is not something one can typically gain in a formal school curriculum or study in the fine arts. Instead, these traditions are passed along informally from one individual to another either through verbal instruction or demonstr ...

Bonneville Dam
Bonneville Lock and Dam consists of several run-of-the-river dam structures that together complete a span of the Columbia River between the U.S. states of Oregon and Washington at River Mile 146.1. The dam is located east of Portland, Oregon, in the Columbia River Gorge. The primary functions of Bonneville Lock and Dam are electrical power generation and river navigation. The dam was built and is managed by the United States Army Corps of Engineers. At the time of its construction in the 1930s it was the largest water impoundment project of its type in the nation, able to withstand flooding on an unprecedented scale. Electrical power generated at Bonneville is distributed by the Bonneville Power Administration. Bonneville Lock and Dam is named for Army Capt. Benjamin Bonneville, an early explorer credited with charting much of the Oregon Trail. The Bonneville Dam Historic District was designated a National Historic Landmark District in 1987.

Cascades Rapids
The Cascades Rapids (sometimes called Cascade Falls or Cascades of the Columbia) were an area of rapids along North America's Columbia River, between the U.S. states of Washington and Oregon. Through a stretch approximately wide, the river dropped about in . These rapids or cascades, along with the many cascades along the Columbia River Gorge in this area of Oregon and Washington, gave rise to the name for the surrounding mountains: the Cascade Range. In 1896 the Cascade Locks and Canal were constructed to bypass the rapids. In the late 1930s, the construction of the Bonneville Dam led to the submerging of the rapids and most of the 1896 structures. Fishing site The rapids were an important fishing site for Native Americans, who would catch salmon as they swam upriver to spawn. Obstacle on Oregon Trail They also posed a major obstacle to the development of the Oregon Trail; initially, pioneers would gather at The Dalles to await small boats to carry them to the Willam ...

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 ...
