George Inlet
George Inlet (also George Arm) is a bay in the U.S. state of Alaska. It is situated within the Alexander Archipelago at the southern shore of Revillagigedo Island. It was named by the U.S. National Geodetic Survey in 1880 after pilot W. E. George, who created the first sketch of Revillagigedo Channel and Tongass Narrows. Geography George Inlet is a deep indentation of the southwestern coast line of Revillagigedo Island. The bed rock is chiefly black phyllite and slates of the Ketchikan series. The boundary of the granite of the Coast Range is probably to the northeast of the upper end of the inlet. The argillite series is often graphitic, and usually closely folded. Some belts of limestone occur with the Ketchikan series near the upper end of the inlet. Greenstones were found not to be so prevalent a rock type as elsewhere in the Ketchikan series. Near the entrance the two shores of the inlet are formed by granite, which occurs in the phyllites as an intrusive stock. The ore deposit ...

Alaska
Alaska ( ; russian: Аляска, Alyaska; ale, Alax̂sxax̂; ; ems, Alas'kaaq; Yup'ik: ''Alaskaq''; tli, Anáaski) is a state located in the Western United States on the northwest extremity of North America. A semi-exclave of the U.S., it borders the Canadian province of British Columbia and the Yukon territory to the east; it also shares a maritime border with the Russian Federation's Chukotka Autonomous Okrug to the west, just across the Bering Strait. To the north are the Chukchi and Beaufort Seas of the Arctic Ocean, while the Pacific Ocean lies to the south and southwest. Alaska is by far the largest U.S. state by area, comprising more total area than the next three largest states (Texas, California, and Montana) combined. It represents the seventh-largest subnational division in the world. It is the third-least populous and the most sparsely populated state, but by far the continent's most populous territory located mostly north of the 60th parallel, with ...

Alexander Archipelago
The Alexander Archipelago (russian: Архипелаг Александра) is a long archipelago (group of islands) in North America lying off the southeastern coast of Alaska. It contains about 1,100 islands, the tops of submerged coastal mountains that rise steeply from the Pacific Ocean. Deep channels and fjords separate the islands and cut them off from the mainland. The islands shelter the northern part of the Inside Passage as it winds its way among them. The islands have irregular, steep coasts and dense evergreen and temperate rain forests; most are accessible only by boat or by aeroplane. The vast majority of the islands are part of the Tongass National Forest. In order of land area, the largest islands are Prince of Wales Island, Chichagof Island, Admiralty Island, Baranof Island, Revillagigedo Island, Kupreanof Island, Kuiu Island, Etolin Island, Dall Island, Wrangell Island, Mitkof Island, Zarembo Island, Kosciusko Island, Kruzof Island, Annette Island, Gravin ...

Tongass Narrows
Tongass Narrows is a Y-shaped channel, part of Southeast Alaska's Inside Passage. The waterway forms part of the Alaska Marine Highway and as such, is used by charter, commercial fishing, and recreational vessels, as well as commercial freight barges and tanks, kayaks and passenger ferries. A proposal to build the Gravina Island Bridge across the Tongass Narrows was shelved due to a national-level controversy over the "bridge to nowhere". Geography Tongass Narrows is defined as the water body that extends from the Revillagigedo Channel to the Gravina Island in Clarence Strait. It is shaped as a "Y", split into two channels by Pennock Island. At its northern end is Clarence Strait. In the southeast it extends from Nichols Passage to Guard Island. The eastern side is bounded by Revillagigedo Island and the west by Gravina Island. The eastern side of the narrows includes the cities of Saxman and Ketchikan. Ketchikan International Airport is located on Gravina Island. The channel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Country Rock (geology)
In geology, country rock is the rock native to an area, in contrast to any intrusion of viscous geologic material, commonly magma, or perhaps rock salt (in salt domes) or unconsolidated sediments. Magma is typically less dense than the rock it intrudes, widening and filling existing cracks, sometimes melting the already-existing country rock. The term "country rock" is similar to, and in many cases interchangeable with, the terms basement and wall rocks. Country rock can denote the widespread lithology of a region in relation to the rock which is being discussed or observed. Geologic settings Settings in geology when the term ''country rock'' is used include: Igneous intrusions When describing a pluton or dike, the igneous rock can be described as intruding the surrounding ''country rock'', the rock into which the pluton has intruded.Newfoundland and LabradorGlossary of Geological Terms Accessed June 2018.

Photograph Taken From N952DB Shortly Before The Collision
A photograph (also known as a photo, image, or picture) is an image created by light falling on a photosensitive surface, usually photographic film or an electronic image sensor, such as a CCD or a CMOS chip. Most photographs are now created using a smartphone/camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would see. The process and practice of creating such images is called photography. Etymology The word ''photograph'' was coined in 1839 by Sir John Herschel and is based on the Greek φῶς (''phos''), meaning "light," and γραφή (''graphê''), meaning "drawing, writing," together meaning "drawing with light." History The first permanent photograph, a contact-exposed copy of an engraving, was made in 1822 using the bitumen-based "heliography" process developed by Nicéphore Niépce. The first photographs of a real-world scene, made using a camera obscura, followed a few years later at Le Gras, Fra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
De Havilland Canada DHC-2 Beaver
The de Havilland Canada DHC-2 Beaver is a single-engined high-wing propeller-driven short takeoff and landing (STOL) aircraft developed and manufactured by de Havilland Canada. It has been primarily operated as a bush plane and has been used for a wide variety of utility roles, such as cargo and passenger hauling, aerial application (crop dusting and aerial topdressing), and civil aviation duties. Shortly after the end of the Second World War, de Havilland Canada decided to orient itself towards civilian operators. Based on feedback from pilots, the company decided that the envisioned aircraft should have excellent STOL performance, all-metal construction, and accommodate many features sought by the operators of bush planes. On 16 August 1947, the maiden flight of the aircraft, which had received the designation ''DHC-2 Beaver'', took place. In April 1948, the first production aircraft was delivered to the Ontario Department of Lands and Forests. A Royal New Zealand Air Forc ...

De Havilland Canada DHC-3 Otter
The de Havilland Canada DHC-3 Otter is a single-engined, high-wing, propeller-driven, short take-off and landing ( STOL) aircraft developed by de Havilland Canada. It was conceived to be capable of performing the same roles as the earlier and highly successful Beaver, including as a bush plane, but is overall a larger aircraft. Design and development The rugged single-engined, high-wing, propeller-driven DHC-3 Otter was conceived in January 1951 by de Havilland Canada as a larger, more powerful version of its highly successful DHC2 Beaver STOL utility transport. Dubbed the "King Beaver" during design, it would be the veritable "one-ton truck" to the Beaver's "half-ton" role. The Otter received Canadian certification in November 1952 and entered production shortly thereafter. Using the same overall configuration as the Beaver, the new, much heavier design incorporated a longer fuselage, greater-span wing, and cruciform tail. Seating in the main cabin expanded from six to 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Transportation Safety Board
The National Transportation Safety Board (NTSB) is an independent U.S. government investigative agency responsible for civil transportation accident investigation. In this role, the NTSB investigates and reports on aviation accidents and incidents, certain types of highway crashes, ship and marine accidents, pipeline incidents, bridge failures, and railroad accidents. The NTSB is also in charge of investigating cases of hazardous materials releases that occur during transportation. The agency is based in Washington, D.C. It has four regional offices, located in Anchorage, Alaska; Denver, Colorado; Ashburn, Virginia; and Seattle, Washington. The agency also operates a national training center at its Ashburn facility. History The origin of the NTSB was in the Air Commerce Act of 1926, which assigned the United States Department of Commerce responsibility for investigating domestic aviation accidents. Before the NTSB, the Federal Aviation Administration's (FAA; at the t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Capstone Program
The Capstone Program was a United States government-funded aviation safety program for the state of Alaska, primarily focusing on rural areas of the state. This joint effort – between the Federal Aviation Administration (FAA), the Alaska Pilot's Association, commercial operators, the University of Alaska, MITRE Corporation, some avionics manufacturers and individual pilots – cut the accident rate in the eastern part of Alaska by around 40%. The program ran from 1999 until 2006, when the FAA integrated it into the national automatic dependent surveillance – broadcast (ADS–B) program. Background Alaska is the largest state in the United States by area, but is one of the smallest in population. In the late 1990s, one out of every 58 people in the state was a pilot, with six airplanes for every ten pilots. With a very limited highway and railroad infrastructure, aviation emerged as the essential – and in most locations the only – transportation system. However, the vital i ...
