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 largest city is Coos Bay, population 16,700 in Coos County on the South Coast. U.S. Route 101 is the primary highway from Brookings to Astoria and is known for its scenic overlooks of the Pacific Ocean. Over 80 state parks and recreation areas dot the Oregon Coast. However, only a few highways cross the Coast Range to the interior: US 30, US 26, OR 6, OR 22,US 20, OR 18, OR 34, OR 126, OR 38, and OR 42. OR 18 and US 20 are considered among the dangerous roads in the state.
The Oregon Coast includes Clatsop County, Tillamook County, Lincoln County, western Lane County, western Douglas County, Coos County, and Curry County.

Geography

The Oregon Coast is divided into three different regions based on their geological formations: the North Coast, Central Coast, and South Coast. Three primary landforms appear along its shoreline: sea cliffs, beaches, and stacks. Minor land variation, city size, and socioeconomic differences between the North and Central regions cause division between them to be made along geological lines.

North Coast

The North Coast, which stretches from the Columbia River to Cascade Head, possesses longer stretches of unbroken beach, a higher concentration of logging zones, and larger, but less frequent sandbar-enclosed bays. Astoria serves as a staging ground for ships entering and leaving the Columbia River, because of the dangerous Columbia Bar. Ships wishing to make the passage require the aid of specially trained bar pilots. Along the coast are the cities of Seaside, Cannon Beach and Tillamook. Seaside and Cannon Beach lie directly on the Pacific Ocean, whereas Tillamook lies inland along Tillamook Bay. Because of the low lands that exist on this region of coast, flooding is an annual problem, especially in the winter, when storms push in from the North Pacific. Tillamook is particularly affected by these yearly floods, because of its location on a major floodplain. Sandstone cliffs occur rather sporadically in this region. This is due to relatively slow uplift rates as well as fairly constant sediment wash from the Columbia River. Future uplift from the subduction of the Juan de Fuca Plate will eventually create sandstone cliffs similar to those found further south and north. The North Oregon Coast is also a part of the Graveyard of the Pacific.
The weather on the North Coast is moderate. The average low in the winter is just under, while the high temperature is just above. The average high reaches its peak in early September at. The most rain occurs in November and December averaging over each month. July and August are the driest averaging under of rain each month. Most days are cloudy or partly cloudy throughout the year. The summer has the most sun with approximately half the days sunny or partly cloudy.

Central Coast

The Central Coast, which extends from Cascade Head to Reedsport, while similar to the North Coast, possesses fewer sandy beaches, more sea cliffs and terraces, and a greater number of bays. Several small urban areas exist in this region. Among these are the cities of Lincoln City, Depoe Bay, Newport, Waldport, and Yachats. Because the usable lands of the region are squeezed between the mountains and the ocean, most urban areas are relatively small but are still larger than those of the South Coast region. The southernmost area of Central coast is the intermediary zone for this region and the more mountainous South Coast region. Exposed sandstone cliffs are also common along the beaches and highway. Local sandstones of the Central Coast were uplifted during the Neogene Era. Higher layers of exposed sandstone are often varying shades of orange, and are often quite soft to the touch, often being very brittle, and relatively easily eroded. Lower exposed layers, though less frequent, reveal harder sandstone deposits. Unlike the higher layers, they are often gray-brown in color and hard in comparison. This lower sandstone often breaks off in large, squared chunks.
The weather on the central coast is similar to that of the north coast except the frequency of sunny or partly cloudy days is higher in the summer, approaching 75%.

South Coast

The South Coast region, which extends from Reedsport to the California border, is distinct from the North and Central Coast regions because of its mountainous nature, due to tectonic uplift and terrane accretion in ancient times. Much of the coastline in this region is made up of sea cliffs and miles of beaches. Among the landscape of the region exists the Oregon Dunes. There are seven incorporated cities on the south coast: Reedsport, North Bend, Coos Bay, Bandon, Port Orford, Gold Beach, and Brookings. Cape Blanco, which is approximately north of Port Orford, is the westernmost point in Oregon. Cape Blanco extends further west than any point of land in the contiguous United States except Cape Alava, in Washington. Though the landforms of the region are relatively consistent, the South Coast shows a change in ecology. It is in this region that the western redcedar and Sitka spruce forests give way to the more southerly coast redwood, Port Orford cedar, and Douglas-fir forests, which also include the northern extent of Oregon Myrtle trees.
The weather on the south coast is similar to that of the north and central coasts except the frequency of sunny or partly cloudy days is higher in the summer, approaching 90%.

Communities

Cities

Because of the Oregon Coast's physical complexity, many different species of plant and animal can be found in the region, both terrestrial and marine in nature. However, past human interaction has caused a decline in several species of animal along the coast, such as the sea otter. Strict regulations as well as modern human aid has seen a return of some species in recent years.
The Oregon Coast is the location of the Oregon Coast National Wildlife Refuge Complex, which consists of six wildlife refuges, covering, spread over a distance of.

Land

Due to several factors, including climate, weather, and terrain, there is a great variety of plants within the coast region. In some areas, large trees are uncommon. This is because severe winter storms and poor soil limit the growing height of many species. Shore pine ' are common in these areas. However several species of fir, pine, and cedar can be found, including a few endemic species, such as the Port Orford cedar '. Because of this, logging has been a historically viable trade for the region. In the North Coast region near Astoria, and in Lincoln County, large tracts of land are second and third generation woodland, having been logged and replanted in the past.
Because of the salt carried inland by constant onshore winds, only the hardiest varieties of small plant can thrive close to shore. Coastal strawberry and Pacific silverweed are common along the coast due to their reproductive advantages and salt tolerance.
Like many forested regions of the western United States and Canada, many large species of animal can be found in the woods of the region. Most common are the Roosevelt elk and black-tailed deer, as well as bobcats and North American cougar. All four species, though common now, were uncommon in the past, having moved more heavily into the region with the beginning of timber harvest. Likewise, smaller species, including nutrias and Virginia opossum can also be found, as well as the Townsend's mole, which inhabits many lowland and floodplain areas.
