Mud Volcano
A mud volcano or mud dome is a landform created by the eruption of mud or slurries, water and gases. Several geological processes may cause the formation of mud volcanoes. Mud volcanoes are not true igneous volcanoes as they do not produce lava and are not necessarily driven by magmatic activity. Mud volcanoes may range in size from merely 1 or 2 meters high and 1 or 2 meters wide, to 700 meters high and 10 kilometers wide. Smaller mud exudations are sometimes referred to as mud-pots. The mud produced by mud volcanoes is mostly formed as hot water, which has been heated deep below the Earth's surface, begins to mix and blend with subterranean mineral deposits, thus creating the mud slurry exudate. This material is then forced upwards through a geological fault or fissure due to local subterranean pressure imbalances. Mud volcanoes are associated with subduction zones and about 1100 have been identified on or near land. The temperature of any given active mud volcano generally r ...

Tahltan Highland
The Tahltan Highland is an upland area of plateau and relatively lower mountain ranges in British Columbia, Canada, lying east of the Boundary Ranges and south of the Inklin River (the east fork of the Taku River). Its eastern boundary is formed by the Sheslay River and the Little Tuya River, while its southern boundary extends across the Stikine River and its Grand Canyon of the Stikine, Grand Canyon to include the Mount Edziza volcanic complex (which includes the Spectrum Range), and the Zagoddethchino massif.

Shield Volcano
A shield volcano is a type of volcano named for its low profile, resembling a warrior's shield lying on the ground. It is formed by the eruption of highly fluid (low viscosity) lava, which travels farther and forms thinner flows than the more viscous lava erupted from a stratovolcano. Repeated eruptions result in the steady accumulation of broad sheets of lava, building up the shield volcano's distinctive form. Shield volcanoes are found wherever fluid low-silica lava reaches the surface of a rocky planet. However, they are most characteristic of ocean island volcanism associated with hot spots or with continental rift volcanism. They include the largest volcanoes on earth, such as Tamu Massif and Mauna Loa. Giant shield volcanoes are found on other planets of the Solar System, including Olympus Mons on Mars and Sapas Mons on Venus. Etymology The term 'shield volcano' is taken from the German term ''Schildvulkan'', coined by the Austrian geologist Eduard Suess in 1888 an ...

Mountain Range
A mountain range or hill range is a series of mountains or hills arranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny. Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics. Mountain ranges are also found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets. Mountain ranges are usually segmented by highlands or mountain passes and valleys. Individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, and volcanic landforms resulting in a variety of rock types. Major ranges Most geolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heart Peaks
Heart Peaks, originally known as the Heart Mountains, is a mountain massif in the Northern Interior of British Columbia, Canada. It is northwest of the small community of Telegraph Creek and just southwest of Callison Ranch. With a maximum elevation of , it rises above the surrounding landscape on the Nahlin Plateau, which is part of the western Stikine Plateau. Heart Peaks has been an area of prospecting since the 1980s with the discovery of precious metals. Situated in a large area of volcanic activity, Heart Peaks consists of a large shield volcano. It was formed in the past 23 million years by repeated eruptions of lava and rock. However, present day eruptions have not been observed. A number of related volcanoes are adjacent to Heart Peaks and form an extensive volcanic zone over long. The knowledge of Heart Peaks is limited, especially its eruptive history.

Level Mountain Range
The Level Mountain Range is a small but prominent mountain range occupying the broad summit of Level Mountain in northern British Columbia, Canada. Located between the Tuya River in the east and the Sheslay River in the west, it represents a high point on the Nahlin Plateau. The range is geologically younger than the main mass of Level Mountain, having formed in the last 7.1 million years. An eroded stratovolcano and several lava domes of Miocene-to-Pleistocene age comprise the Level Mountain Range. The highest point is Meszah Peak Meszah Peak is a volcanic cone located north of Telegraph Creek and southwest of Zus Mountain in British Columbia, Canada.

Spatsizi Plateau
The Spatsizi Plateau is a plateau in the upper basin of the Stikine River in north-central British Columbia, Canada. Most of the plateau, which is a sub-plateau of the Stikine Plateau, is enshrined in either Spatsizi Plateau Wilderness Provincial Park or Spatsizi Headwaters Provincial Park. It is flanked on the south and southwest by the Skeena Mountains, on the southeast by the Omineca Mountains, on the northeast by the Stikine Ranges of the Cassiar Mountains, and on the west by the Klastline Plateau (another subplateau of the Stikine Plateau). Name The name is an adaptation of a phrase in the Sekani language meaning "red goat", a reference to the habit of mountain goats in the area rolling on a particular red-coloured mountain, turning their coats red (''tspah''=goat, ''tsije''=red). Geology and terrain The plateau is a large lava plateau, dissected by river valleys, and contains various small mountain ranges. Both the Stikine and Spatsizi Rivers have their sources in the p ...

British Columbia
British Columbia (commonly abbreviated as BC) is the westernmost province of Canada, situated between the Pacific Ocean and the Rocky Mountains. It has a diverse geography, with rugged landscapes that include rocky coastlines, sandy beaches, forests, lakes, mountains, inland deserts and grassy plains, and borders the province of Alberta to the east and the Yukon and Northwest Territories to the north. With an estimated population of 5.3million as of 2022, it is Canada's third-most populous province. The capital of British Columbia is Victoria and its largest city is Vancouver. Vancouver is the third-largest metropolitan area in Canada; the 2021 census recorded 2.6million people in Metro Vancouver. The first known human inhabitants of the area settled in British Columbia at least 10,000 years ago. Such groups include the Coast Salish, Tsilhqotʼin, and Haida peoples, among many others. One of the earliest British settlements in the area was Fort Victoria, established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stikine River
The Stikine River is a major river in northern British Columbia (BC), Canada and southeastern Alaska in the United States. It drains a large, remote upland area known as the Stikine Country east of the Coast Mountains. Flowing west and south for , it empties into various straits of the Inside Passage near Wrangell, Alaska. About 90 percent of the river's length and 95 percent of its drainage basin are in Canada.Lehner, B., Verdin, K., Jarvis, A. (2008)New global hydrography derived from spaceborne elevation data Eos, Transactions, AGU, 89(10): 93–94. Considered one of the last truly wild large rivers in BC, the Stikine flows through a variety of landscapes including boreal forest, steep canyons and wide glacial valleys. Known as the "fastest-flowing navigable river in North America," the Stikine forms a natural waterway from northern interior British Columbia to the Pacific coast. The river has been used for millennia by indigenous peoples including the Tlingit an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
