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 362 miles (583 km) 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 Nehalem River is a river on the Pacific coast of northwest Oregon in the United States, approximately 119 miles (192 km) long. It drains part of the Northern Oregon Coast Range northwest of Portland, originating on the east side of the mountains and flowing in a loop around the north end of the range near the mouth of the Columbia River. Its watershed of 855 square miles (2,210 km2) includes an important timber-producing region of Oregon that was the site of the Tillamook Burn. In its upper reaches it flows through a long narrow valley of small mountain communities but is unpopulated along most of its lower reaches inland from the coast.
The Salmonberry River is a tributary of the Nehalem River, about 20 miles (32 km) long, in northwest Oregon in the United States. It drains a remote unpopulated area of the Northern Oregon Coast Range in the Tillamook State Forest about 65 miles (105 km) west-northwest of Portland. The river runs through part of the region devastated between 1933 and 1951 by a series of wildfires known as the Tillamook Burn.
The Clatsop is a small tribe of Chinookan-speaking Native Americans in the Pacific Northwest of the United States. In the early 19th century they inhabited an area of the northwestern coast of present-day Oregon from the mouth of the Columbia River south to Tillamook Head, Oregon.
Tillamook Head is a high promontory on the Pacific coast of northwest Oregon in the United States. It is located in west-central Clatsop County, approximately 5 mi (8 km) southwest of Seaside. The promontory forms a steep rocky bluff on the ocean, approximately 1,200 ft high, forested with Sitka spruce. It is located in Ecola State Park.
The Siletz were the southernmost of several divisions of the Tillamook people speaking a distinct dialect; the other dialect-divisions were: Salmon River on the Salmon River, Nestucca on Little Nestucca River, Nestucca River and Nestucca Bay, Tillamook Bay on the Tillamook Bay and the mouths of the Kilchis, Wilson, Trask and Tillamook rivers, and Nehalem on Nehalem River. The name "Siletz" comes from the name of the Siletz River on which they live. The origin of the name is unknown
The Cascadia subduction zone is a 960 km fault at a convergent plate boundary, about 112-160 km off the Pacific Shore, 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 30m. 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 at about Vancouver Island in British Columbia.
The Oregon Coast Trail (OCT) is a long-distance hiking route along the Pacific coast of the U.S. state of Oregon in the United States. It follows the coast of Oregon from the mouth of the Columbia River to the California border south of Brookings.
Tillamook Rock Light is a deactivated lighthouse on the northern Oregon Coast of the United States. It is located approximately 1.2 miles (1.9 km) offshore from Tillamook Head, and 20 miles (32 km) south of the mouth of the Columbia River near Astoria, situated on less than an acre of basalt rock in the Pacific Ocean. The construction of the lighthouse was commissioned in 1878 by the United States Congress and took more than 500 days to complete. Shortly before the completion of the lighthouse in January 1881, the barque Lupatia was wrecked near the rock during foggy weather and sank, with the loss of all 16 crew members.
The Blanco Fracture Zone or Blanco Transform Fault Zone (BTFZ) is a right lateral transform fault zone, which runs northwest off the coast of Oregon in the Pacific Northwest of the United States, extending from the Gorda Ridge in the south to the Juan de Fuca Ridge in the north.
The Oregon Coast Range, often called simply the Coast Range and sometimes the Pacific Coast Range, is a mountain range, in the Pacific Coast Ranges physiographic region, in the U.S. state of Oregon along the Pacific Ocean. This north-south running range extends over 200 miles (320 km) from the Columbia River in the north on the border of Oregon and Washington, south to the middle fork of the Coquille River. It is 30 to 60 miles wide and averages around 1,500 feet (460 m) in elevation above sea level. The coast range has three main sections, a Northern, Central, and Southern.
The Oregon Coast National Wildlife Refuge Complex consists of six National Wildlife Refuges along the Oregon Coast. It provides wilderness protection to thousands of small islands, rocks, reefs, headlands, marshes, and bays totaling 371 acres spanning 320 miles (515 km) of Oregon's coastline. The areas are all managed by the United States Fish and Wildlife Service.
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 371 acres (150 ha) spanning 1,083 acres (438 ha) 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. The area is managed by the United States Fish and Wildlife Service.
Sponge reefs are reefs formed by Hexactinellid sponges, which have a skeleton made of silica, and are often referred to as glass sponges. Such reefs are now very rare, and found only in waters off the coast of British Columbia, Washington and southern Alaska. Recently sponge reefs were identified within the strait of Georgia and Howe sound close to Vancouver. Although common in the late Jurassic period, reef-building sponges were believed to have gone extinct during or shortly after the Cretaceous period, until the existing reefs were discovered in Queen Charlotte sound in 1987–1988 – hence these sometimes being dubbed living fossils.
The Tillamook are a Native American tribe from coastal Oregon of the Salish linguistic group. The name "Tillamook" is a Chinook language term meaning "people of [the village] Nekelim ", sometimes it is given as a Coast Salish term, meaning "Land of Many Waters". The Tillamook tribe consists of several divisions and dialects, including :
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. Many of the stumps are over 2,000 years old.
The Salmonberry Trail is a planned rail trail hiking and biking trail through the Oregon Coast Range along the Salmonberry River in northwest Oregon, United States. A portion of the Port of Tillamook Bay Railroad was washed out by a storm in 2007. In 2012, advocacy efforts to build a trail were launched, and in 2018, the Salmonberry Trail Intergovernmental Agency was established to oversee the development of the trail.
Heceta Bank is a rocky bank located 55 kilometers (km) off the Oregon coast near Florence, centered on approximately 44°N, 125°W, and is roughly 29 km long and upwards of 13 km wide. Heceta Bank is an area of ecological and oceanographic importance. The unique bathymetric features and seasonal circulation within the bank provides habitat for a diversity of economically-important fish species.
Stonewall Bank, also, the Stonewall Bank Yelloweye Rockfish Conservation Areas (YRCA) is a bar, loosely southwest of Newport, Oregon, United States. Waldport and Yachats are also near. It is 17 miles (27 km) southwest of Yaquina Bay Light, and 14 miles (23 km) offshore. Running north, Stonewall Bank is 9 miles (14 km) long and 2.5 miles (4.0 km) wide. Locally, Stonewall Bank is known as the Rock Pile, has good fishing for salmon, black rockfish and flatfish.
