Gareloi Island
Gareloi (russian: Горелый) or Anangusook ( ale, Anangusix̂) is a volcanic island in the Delarof Islands of the Aleutian Islands of Alaska. It is located between the Tanaga Pass and the Amchitka Pass. The island is in length and wide. Its land area is , making Gareloi the largest island in the Delarof group. Gareloi Volcano, a stratovolcano A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and per ..., is situated in the center of the island which reaches a height of . On the other side of a small saddle lies another peak of the island however it does not equal the height of Mount Gareloi. The island is uninhabited. Coastal cliffs provide nesting habitat for more than 600,000 seabirds, mostly for crevice nesting auklets. Least Auklets account for 62% of the colony, Crested Auklets ...

Gareloi Volcano
Mount Gareloi, or Gareloi Volcano, is a stratovolcano in the Aleutian Islands of Alaska, United States, about from Anchorage. Gareloi is located on Gareloi Island, and comprises most of its land mass. The island also has two small glaciers which protrude to the northwest and southeast.Alaska Volcano Observatory, Volcano Information -- Gareloi Retrieved Dec. 16, 2022. The volcano is by at its base, possessing two summits. The southern crater is far greater in size, wide with s, which can be attributed to edifice failure in the southern wall, while Gareloi's northern crater is enclosed. Discovery and accessibility |
Stratovolcanoes Of The United States
A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high-to-intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less-viscous mafic magma. Extensive felsic lava flows are uncommon, but have travelled as far as . Stratovolcanoes are sometimes called composite volcanoes because of their composite stratified structure, built up from sequential outpourings of erupted materials. They are among the most common types of volcanoes, in contrast to the less common shield volc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanoes Of Unorganized Borough, Alaska
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide pa ...

The list of uninhabited regions includes a number of places around the globe. The list changes year over year as human beings migrate into formerly uninhabited regions, or migrate out of formerly inhabited regions.

Landforms Of Aleutians West Census Area, Alaska
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features.

Amchitka Pass
Amchitka Pass is a strait in Alaska, United States. It is located in the Aleutian Islands on the 180th meridian, between the Rat Islands group to the west and the Delarof Islands The Delarof Islands ( ale, Naahmiĝun tanangis; russian: Острова Деларова) (ca. ) are a group of small islands at the extreme western end of the Andreanof Islands group in the central Aleutian Islands, Alaska. The Delarofs consist ... to the east. Amchitka Pass has a least width of 50 miles (80.5 km) and depths of 249 feet (76 meters) to over 6,000 feet (1,829 meters). The islands on both sides of the pass should be cleared by at least 5 miles (8 km). Heavy tide rips have been observed off the east end of Amchitka Island. The pass is dangerous in heavy weather, particularly for small and medium craft; currents appear erratic in direction and velocities may be strong. This may account for reports of very large seas and strong tide rips. References Straits of Aleutians West Census Ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tanaga Pass
The Tanaga Pass is a strait between Tanaga Island and the Delarof Islands the Aleutian Islands of 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 is about long and wide at its narrowest part. Tidal currents commonly range between two and three knots in the pass. From the U.S. Coast Pilot: "Depths of 50 fathoms or more can be carried through the pass by keeping off Cape Amagalik, Tanaga Island, and off the Delarof Islands. "The direction and velocity of the current is radically affected by the land areas and the banks. It appears that the flood is diverted by the chain of islands – Skagul to Unalga – and the relatively shoal water between them to an east and west direction in moving around this chain. It was observed that south of Skagul Island the flood sets ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...
