Neskowin Ghost Forest
The Neskowin Ghost Forest is the remnants of a Sitka spruce forest on the Oregon Coast of the United States. The stumps were likely created when an earthquake of the Cascadia subduction zone abruptly lowered the trees, that were then covered by mud from landslides or debris from a tsunami. Although many local geologists believe this ghost forest (and others on the Pacific NW coast) were caused by gradual dune encroachment, meaning sand dunes built up and covered the Sitka trees – not in an abrupt drop.Hart, R., & Peterson, C. (2007). Late‐Holocene buried forests on the Oregon Coast. Earth Surface Processes and Landforms, 32(2), 210-229. Many of the stumps are over 2,000 years old, preserved by the salt water, which does not favor lignin-decomposing fungus. History The stumps were unearthed when turbulent storms swept away sand during the winter of 1997–1998. It is one of over thirty ghost forests along the Oregon and Washington Coast, though many appear as flat roots and not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sitka Spruce
''Picea sitchensis'', the Sitka spruce, is a large, coniferous, evergreen tree growing to just over tall, with a trunk diameter at breast height that can exceed 5 m (16 ft). It is by far the largest species of spruce and the fifth-largest conifer in the world (behind giant sequoia, coast redwood, kauri, and western red cedar), and the third-tallest conifer species (after coast redwood and South Tibetan cypress). The Sitka spruce is one of only five species documented to exceed in height. Its name is derived from the community of Sitka in southeast Alaska, where it is prevalent. Its range hugs the western coast of Canada and the US and continues south into northern California. Description The bark is thin and scaly, flaking off in small, circular plates across. The inner bark is reddish-brown. The crown is broad conic in young trees, becoming cylindric in older trees; old trees may not have branches lower than . The shoots are very pale buff-brown, almost w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oregon Coast
The Oregon Coast is a coastal region of the U.S. state of Oregon. It is bordered by the Pacific Ocean to its west and the Oregon Coast Range to the east, and stretches approximately from the California state border in the south to the Columbia River in the north. The region is not a specific geological, environmental, or political entity, and includes the Columbia River Estuary. The Oregon Beach Bill of 1967 allows free beach access to everyone. In return for a pedestrian easement and relief from construction, the bill eliminates property taxes on private beach land and allows its owners to retain certain beach land rights. Traditionally, the Oregon Coast is regarded as three distinct sub–regions: * The North Coast, which stretches from the Columbia River to Cascade Head, Oregon, Cascade Head. * The Central Coast, which stretches from Cascade Head to Reedsport, Oregon, Reedsport. * The South Coast, which stretches from Reedsport to the U.S. Route 101 in Oregon#Brookings to C ...

Cascadia Subduction Zone
The Cascadia subduction zone is a convergent plate boundary, about off the Pacific coast of North America, that stretches from northern Vancouver Island in Canada to Northern California in the United States. It is capable of producing 9.0+ magnitude earthquakes and tsunamis that could reach 30 m (100 ft) high. The Oregon Department of Emergency Management estimates shaking would last 5–7 minutes along the coast, with strength and intensity decreasing further from the epicenter. It is a very long, sloping subduction zone where the Explorer, Juan de Fuca, and Gorda plates move to the east and slide below the much larger mostly continental North American plate. The zone varies in width and lies offshore beginning near Cape Mendocino, Northern California, passing through Oregon and Washington, and terminating in Canada at about Vancouver Island in British Columbia. The Explorer, Juan de Fuca, and Gorda plates are some of the remnants of the vast ancient Farallon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tsunami
A tsunami ( ; from , ) is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and underwater explosions (including detonations, landslides, glacier calvings, meteorite impacts and other disturbances) above or below water all have the potential to generate a tsunami. Unlike normal ocean waves, which are generated by wind, or tides, which are in turn generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water from a large event. Tsunami waves do not resemble normal undersea currents or sea waves because their wavelength is far longer. Rather than appearing as a breaking wave, a tsunami may instead initially resemble a rapidly rising tide. For this reason, it is often referred to as a tidal wave, although this usage is not favoured by the scientific community because it might give the false impression of ...

Ghost Forest
Ghost forests are areas of dead trees in former forests, typically in coastal regions where Sea level rise, rising sea levels or tectonic shifts have altered the height of a land mass. Forests located near the coast or estuary, estuaries may also be at risk of dying through saltwater poisoning, if invading seawater reduces the amount of freshwater that deciduous trees receive for sustenance. Phantom forest, Phantom forests refer to a different issue with forests. Formations Sea level changes When there is a change in sea level, coastal regions may become inundated with sea water. This can alter coastal areas and kill large areas of trees, leaving behind what is called a “ghost forest.” This type of ghost forest may develop in a variety of environments and in many different places. In the Southern United States, southern US, coastal marshes are expanding into dry wooded areas, killing trees and leaving behind areas of dead trees called snags. Regions of the US at or below se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 plate slipped an average of along a fault rupture about long. 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 9:00 PM Pacific Time on the evening of 26 January 1700. Japanese records The earthquake took place at about 21:00 PT 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 moder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to ...

Proposal Rock (Oregon)
Proposal Rock is an island off Oregon Coast, the coast of the U.S. state of Oregon, in Tillamook County, Oregon, Tillamook County, near the community of Neskowin, Oregon, Neskowin. The island is named for a local legend of a sea captain taking his beloved there to Marriage proposal, propose to her.Ralph Friedman, ''In Search of Western Oregon'' (1990), p. 40. The proposal was from Charley Gage to Della Page sometime around 1900. Della's mother, Sarah, then dubbed it Proposal Rock to mark the occasion. Proposal Rock was originally called “Schlock” by the Native Americans who first lived there.

Tillamook County, Oregon
Tillamook County is one of the 36 counties in the U.S. state of Oregon. As of the 2020 census, the population was 27,390. The county seat is Tillamook. The county is named for the Tillamook people or Killamook people, a Native American tribe who were living in the area in the early 19th century at the time of European American settlement. The county is located within Northwest Oregon. History The Tillamook were the southernmost branch of the Coast Salish. They were separated from their more northern kinsmen by tribes speaking the Chinookian languages. The name Tillamook is of Chinook origin (a trade pidgin, which had developed along the lower Columbia.) According to Frank Boas, "It illamookmeans the people of Nekelim. The latter name means the place of Elim, or in the Cathlamet dialect, the place of Kelim. The initial t of Tillamook is the plural article, the terminal ook the Chinook plural ending —uks." Since there was one village in the area of Nehalem bay; the area ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Former Forests
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being used in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose cone to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until t ...
