Hetta Inlet
Hetta Inlet is a deep embayment in the southwestern coast of Prince of Wales Island in the U.S. state of Alaska. It connects with the Pacific Ocean through Cordova Bay. The head of the inlet is separated by a divide from the West Arm of Cholmondeley Sound. The shores are abrupt from the water's edge, and the channels and inlets are deep. The precipitation is probably a little greater than at Ketchikan, and the mean annual temperature is slightly higher. The white crystalline limestone of the Wales series, striking nearly north and south, is the predominant country rock of Hetta Inlet. In it are intruded many igneous rocks, some schistose, some massive. The white limestones are closely folded and have great variation in dip. The igneous rocks, so far as determined from the small collection made, include gabbros, diorites, amphibolites, diabases, and pyroxene-syenites. All these are comparatively massive. The greenstoneschists, which occupy considerable areas, are chloritic. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Embayment
A bay is a recessed, coastal body of water that directly connects to a larger main body of water, such as an ocean, a lake, or another bay. A large bay is usually called a gulf, sea, sound, or bight. A cove is a small, circular bay with a narrow entrance. A fjord is an elongated bay formed by glacial action. A bay can be the estuary of a river, such as the Chesapeake Bay, an estuary of the Susquehanna River. Bays may also be nested within each other; for example, James Bay is an arm of Hudson Bay in northeastern Canada. Some large bays, such as the Bay of Bengal and Hudson Bay, have varied marine geology. The land surrounding a bay often reduces the strength of winds and blocks waves. Bays may have as wide a variety of shoreline characteristics as other shorelines. In some cases, bays have beaches, which "are usually characterized by a steep upper foreshore with a broad, flat fronting terrace".Maurice Schwartz, ''Encyclopedia of Coastal Science'' (2006), p. 129.

Prince Of Wales Island (Alaska)
Prince of Wales Island (Tlingit: ''Taan'') is one of the islands of the Alexander Archipelago in the Alaska Panhandle. It is the fourth-largest island in the United States (after Hawaii, Kodiak Island, and Puerto Rico) and the 97th-largest island in the world. Geography and ecology The island is long, wide and has an area of , about one-tenth the size of Ireland and slightly larger than the state of Delaware. Approximately 6,000 people live on the island. Craig is the largest community; founded as a saltery in the early 20th century, it has a population of 1,500. Some 900 people live in Klawock, a long-established village that grew with the fishing industry. Hollis was a boom and bust mining town from 1900 to about 1915. Abandoned, it was re-established as a logging camp in the 1950s. It now has a population of 100 and is the location of the ferry terminal. Mountain peaks, all but the tallest of which were buried by Pleistocene glaciation, reach over . Fjords, steep-si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Cordova Bay
Cordova Bay is a bay in the Alexander Archipelago of southeast Alaska. It opens onto Dixon Entrance to the south, between Cape Muzon on Dall Island and Point Marsh (a group of small islets just off Prince of Wales Island). The name Puerto Cordova y Cordova was given by the Spanish explorer Lieutenant Don Jacinto Caamaño in 1792, in honor of Admiral Luis de Córdova y Córdova. The name was published by George Vancouver in 1798. Cordova Bay is bordered on the west by Dall Island, Long Island, Tlevak Strait, and Sukkwan Island, and on the east by Prince of Wales Island. Cordova Bay extends north and west from its mouth to Lime Point, where it connects with Hetta Inlet. The Coast Survey lists the length as about from a point between the SE corner of Long Island and Dewey Rocks to Lime Point and an average width of about from Ship Islands to Lime Point. Hetta Inlet extends a further north, and then turns east for about . Gould Island almost closes the inlet shortly after it tur ...

Cholmondeley Sound
Cholmondeley Sound is a deep bay or inlet on the southeast side of Prince of Wales Island, in the Alexander Archipelago of southeast Alaska, in Tongass National Forest and connecting to Clarence Strait. The sound's entrance lies between Chasina Point and Skin Island. It is about west of Ketchikan, Alaska. Cholmondeley Sound has several bays and inlets within it, including Kitkun Bay, Dora Bay, Brennan Bay, and Sunny Cove. At its western end Cholmondeley Sound splits into two fjord-like inlets: West Arm Chomondeley Sound, about long, and South Arm Cholmondeley Sound, about long. The full length from the entrance of the sound to the head of West Arm is about . Cholmondeley Sound and its several arms are all deep, with steep and heavily forested shorelines. Cholmondeley Sound was named by George Vancouver on 21 August 1793, for George Cholmondeley, The Earl of Cholmondeley. There was once a Haida summer village, known as Chatchini or Chat-chee-ni, used by the Kaigani Haida of Ka ... [...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. When country rock is intruded by a dike, perpendicular to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tongass National Forest
The Tongass National Forest () in Southeast Alaska is the largest U.S. National Forest at . Most of its area is temperate rain forest and is remote enough to be home to many species of endangered and rare flora and fauna. The Tongass, which is managed by the United States Forest Service, encompasses islands of the Alexander Archipelago, fjords and glaciers, and peaks of the Coast Mountains. An international border with Canada (British Columbia) runs along the crest of the Boundary Ranges of the Coast Mountains. The forest is administered from Forest Service offices in Ketchikan. There are local ranger district offices located in Craig, Hoonah, Juneau, Ketchikan, Petersburg, Sitka, Thorne Bay, Wrangell, and Yakutat. History The Alexander Archipelago Forest Reserve was established by Theodore Roosevelt in a presidential proclamation of 20 August 1902. Another presidential proclamation made by Roosevelt, on 10 September 1907, created the Tongass National Forest. On 1 July ...
