Short Beach (Oregon)
Short Beach is a 1,000-meter stretch of beach on the northern Oregon Coast in the United States; obviously it is not named for its length. Locals guess that both the beach and the creek that runs onto it—Short Creek, several miles in length—were named after an early resident of the area. Just south of Cape Meares State Park, and a bit north of Oceanside, the beach is hidden from the land except for a brief stretch of road which crosses the dam across Short Creek. The seasonal shingle beach is noted for the availability of agates, (the beach is sometimes erroneously called "Agate Beach") and jasper, sometimes called "coastal jade" or "beach jade". Agates and jasper become more available after heavy winter or spring storms, which often cause landslides or rockfalls, bringing fresh parent rock to the beach, where the upper slope is a rock berm. These rock collapses eventually become the smooth, rounded rock familiar on beaches by the pounding surf that brought them down. Oth ...

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. * The Central Coast, which stretches from Cascade Head to Reedsport. * The South Coast, which stretches from Reedsport to the Oregon–California border. The largest city is Coos Bay, population 16,700 i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cape Meares State Park
Cape Meares is a small headland on the Pacific coast in Tillamook County, Oregon, United States. The cape forms a high steep bluff on the south end of Tillamook Bay, approximately five miles (8 km) northwest of the city of Tillamook. Much of the cape is part of the Oregon Parks and Recreation Department-administered Cape Meares State Scenic Viewpoint with three miles of hiking trails, which includes Cape Meares Light and the Octopus Tree. The cape is named after John Meares, a British explorer. Geography Immediately north of the cape is the community of Cape Meares, next to Cape Meares Lake. Cape Meares beach extends north of the community of Cape Meares, along a sand spit, or peninsula, that encloses Tillamook Bay. The peninsula is alternatively known as Bayocean, after a popular upscale resort town that occupied the beach in the early 20th century, until beach erosion began to destroy the town beginning in the 1930s. Today, no significant remnant of the resort tow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shingle Beach
A shingle beach (also referred to as rocky beach or pebble beach) is a beach which is armoured with pebbles or small- to medium-sized cobbles (as opposed to fine sand). Typically, the stone composition may grade from characteristic sizes ranging from diameter. While this beach landform is most commonly found in Europe, examples are found in Bahrain, North America, and a number of other world regions, such as the west coast of New Zealand's South Island, where they are associated with the shingle fans of braided rivers. Though created at shorelines, post-glacial rebound can raise shingle beaches as high as above sea level, as on the High Coast in Sweden. The ecosystems formed by this unique association of rock and sand allow colonization by a variety of rare and endangered species. Formation Shingle beaches are typically steep, because the waves easily flow through the coarse, porous surface of the beach, decreasing the effect of backwash erosion and increasing the formati ...

Agate
Agate () is a common rock formation, consisting of chalcedony and quartz as its primary components, with a wide variety of colors. Agates are primarily formed within volcanic and metamorphic rocks. The ornamental use of agate was common in Ancient Greece, in assorted jewelry and in the seal stones of Greek warriors, while bead necklaces with pierced and polished agate date back to the 3rd millennium BCE in the Indus Valley civilisation. Etymology The stone was given its name by Theophrastus, a Greek philosopher and naturalist, who discovered the stone along the shore line of the Dirillo River or Achates ( grc, Ἀχάτης) in Sicily, sometime between the 4th and 3rd centuries BCE. Formation and properties Agate minerals have the tendency to form on or within pre-existing rocks, creating difficulties in accurately determining their time of formation. Their host rocks have been dated to have formed as early as the Archean Eon. Agates are most commonly found as nodules wi ...

Jasper
Jasper, an aggregate of microgranular quartz and/or cryptocrystalline chalcedony and other mineral phases,Kostov, R. I. 2010. Review on the mineralogical systematics of jasper and related rocks. – Archaeometry Workshop, 7, 3, 209-213PDF/ref> is an opaque, impure variety of silica, usually red, yellow, brown or green in color; and rarely blue. The common red color is due to iron(III) inclusions. Jasper breaks with a smooth surface and is used for ornamentation or as a gemstone. It can be highly polished and is used for items such as vases, seals, and snuff boxes. The specific gravity of jasper is typically 2.5 to 2.9. Jaspillite is a banded-iron-formation rock that often has distinctive bands of jasper. Etymology and history The name means "spotted or speckled stone," and is derived via Old French ''jaspre'' (variant of Anglo-Norman ''jaspe'') and Latin ''iaspidem'' (nom. ''iaspis'') from Greek ἴασπις ''iaspis'' (feminine noun), from an Afroasiatic language (cf. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mussel
Mussel () is the common name used for members of several families of bivalve molluscs, from saltwater and Freshwater bivalve, freshwater habitats. These groups have in common a shell whose outline is elongated and asymmetrical compared with other edible clams, which are often more or less rounded or oval. The word "mussel" is frequently used to mean the bivalves of the marine family Mytilidae, most of which live on exposed shores in the intertidal zone, attached by means of their strong Byssus, byssal threads ("beard") to a firm substrate. A few species (in the genus ''Bathymodiolus'') have colonised hydrothermal vents associated with deep ocean ridges. In most marine mussels the shell is longer than it is wide, being wedge-shaped or asymmetrical. The external colour of the shell is often dark blue, blackish, or brown, while the interior is silvery and somewhat nacreous. The common name "mussel" is also used for many freshwater bivalves, including the freshwater pearl mussels. F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oregon Islands National Wildlife Refuge
Oregon Islands National Wildlife Refuge is a U.S. National Wildlife Refuge off the southwestern Oregon Coast. It is one of six National Wildlife Refuges comprising the Oregon Coast National Wildlife Refuge Complex. The Oregon Islands provides wilderness protection to 1,853 small islands, rocks, and reefs plus two headlands, totaling spanning of Oregon's coastline from the Oregon–California border to Tillamook Head. There are sites in six of the seven coastal counties of Oregon. From north to south they are Clatsop, Tillamook, Lincoln, Lane, Coos, and Curry counties. ( Douglas County is the only coastal Oregon county not included in the refuge.) The area is managed by the United States Fish and Wildlife Service. History The Oregon Islands National Wildlife Refuge was created in 1935 by the federal government. Haystack Rock off Cannon Beach was added to the refuge in 1968, which became a wilderness area in 1978. The first mainland addition to the refuge came in 1991 when Coqu ...

Erosion
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical erosion procee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
