Cape Blanco Light
Cape Blanco Light is a lighthouse located on Cape Blanco, Oregon, United States in Cape Blanco State Park. Construction of the light In a deed recorded in 1867, John D. and Mary West sold the United States a tract of land. The Light-House board determined that the offshore reef A reef is a ridge or shoal of rock, coral or similar relatively stable material, lying beneath the surface of a natural body of water. Many reefs result from natural, abiotic processes— deposition of sand, wave erosion planing down rock o ... and islands at Cape Blanco were dangerous to maritime commerce; therefore, a lighthouse was authorized for construction. Over the next three years, the lighthouse was constructed under the direction of Lt. Col. Robert Stockton Williamson. Supplies were ordered and shipped to the cape. Bricks were deemed cheaper if made onsite, so a brickmaker was located and a deal was struck with Rancher Patrick Hughes for access to the required materials. Keepers ...

Oregon
Oregon () is a U.S. state, state in the Pacific Northwest region of the Western United States. The Columbia River delineates much of Oregon's northern boundary with Washington (state), Washington, while the Snake River delineates much of its eastern boundary with Idaho. The 42nd parallel north, 42° north parallel delineates the southern boundary with California and Nevada. Oregon has been home to many Indigenous peoples of the Americas, indigenous nations for thousands of years. The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early-mid 16th century. As early as 1564, the Spanish expeditions to the Pacific Northwest, Spanish began sending vessels northeast from the Philippines, riding the Kuroshio Current in a sweeping circular route across the northern part of the Pacific. In 1592, Juan de Fuca undertook detailed mapping and studies of ocean currents in the Pacific Northwest, including the Oregon coast as well as ...

Fresnel Lens
A Fresnel lens ( ; ; or ) is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use in lighthouses. It has been called "the invention that saved a million ships." The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens was first proposed by Count Buffon and independently reinvented by Fresnel. The ''catadioptric'' form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source and add it to the beam of a lighthouse, making the light visible from greater distances. Description The Fresnel lens redu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sixes, Oregon
Sixes is an unincorporated community in Curry County, Oregon, United States. It is along U.S. Route 101 and the Sixes River, east of Cape Blanco and the Cape Blanco Lighthouse. Accounts vary as to the origin of the name "Sixes". The community was named after the river. One local postmaster said Sixes was named for a Native American chief. Another source said that in 1851, the river was usually called the "Sikhs River" after the Chinook Jargon word for "friend", and on maps it was called the "Sequalchin River". Another source says the Native American name for the river was "Sa-qua-mi". Hodge's ''Handbook of American Indians'' says that one of the variants of the name of the local tribe, the Kwatami (a subdivision of the Tututni), was "Sik-ses-tene", which is said to mean "people by the far north country". Though this is most likely the real source of the name, the spelling "Sixes" was probably used by miners drawn to the Oregon gold rush who were familiar with the Chinook wor ...

Lighthouse
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Blanco (Oregon)
Cape Blanco is a prominent headland on the Pacific Ocean coast of southwestern Oregon in the United States, forming the westernmost point in the state. Cape Blanco extends further west than any point of land in the contiguous United States (lower 48 states) except portions of the Olympic Peninsula in Washington, including Cape Alava, the true westernmost point. The cape is part of Cape Blanco State Park and is the location of the Cape Blanco Light, first lit in 1870. The cape may have been named by explorer Martín de Aguilar in 1603 for its appearance, as ''blanco'' means "white" in Spanish. In 1775, Juan Francisco de la Bodega y Quadra named the point Cabo Diligensias. It was later renamed Cape Orford by Captain George Vancouver in 1792, but this name fell into disuse and Cape Blanco became the common usage. Geology The cape, a relatively level landform with cliffs facing the sea, is about higher than the ocean. It consists of layers of uplifted marine sediments, ranging in a ...
