Yukon
Yukon () is a Provinces and territories of Canada, territory of Canada, bordering British Columbia to the south, the Northwest Territories to the east, the Beaufort Sea to the north, and the U.S. state of Alaska to the west. It is Canada’s westernmost territory and the smallest territory by land area. As of the 2021 Canadian census, 2021 census, Yukon is the middle territory in terms of population, but the most densely populated. Yukon has an estimated population of 47,126 as of 2025. Whitehorse, the territorial capital, is the largest settlement. Yukon was History of the Northwest Territories, split from the Northwest Territories by a federal statute in 1898 as the Yukon Territory. The current governing legislation is a new statute passed by the federal Parliament in 2002, the ''Yukon Act''. That act established Yukon as the territory's official name, although Yukon Territory remains in popular usage. Canada Post uses the territory's internationally approved postal abbrevia ...

Pacific Coast Ranges
The Pacific Coast Ranges (officially gazetted as the Pacific Mountain System in the United States; ; ) are the series of mountain ranges that stretch along the West Coast of North America from Alaska south to Northern and Central Mexico. Although they are commonly thought to be the westernmost mountain range of the continental United States and Canada, the geologically distinct Insular Mountains of Vancouver Island lie farther west. The Pacific Coast Ranges are part of the North American Cordillera (sometimes known as the Western Cordillera, or in Canada, as the Pacific Cordillera and/or the Canadian Cordillera), which includes the Rocky Mountains, the Columbia Mountains, the Interior Mountains, the Interior Plateau, the Sierra Nevada, the Great Basin mountain ranges, and other ranges and various plateaus and basins. The Pacific Coast Ranges designation, however, only applies to the Western System of the Western Cordillera,S. Holland, ''Landforms of British Columbia'', BC G ...

National Topographic System
The National Topographic System or NTS is the system used by Natural Resources Canada for providing general purpose topographic maps of the country. NTS maps are available in a variety of scales, the standard being 1:50,000 and 1:250,000 scales. The maps provide details on landforms and terrain, lakes and rivers, forested areas, administrative zones, populated areas, roads and railways, as well as other human-made features. These maps are currently used by all levels of government and industry for forest fire and flood control (as well as other environmental issues), depiction of crop areas, right-of-way, real estate planning, development of natural resources and highway planning. To add context, land area outside Canada is depicted on the 1:250,000 maps, but not on the 1:50,000 maps. History Topographic mapping in Canada was originally undertaken by many different agencies, with the Canadian Army’s Intelligence Branch forming a survey division to create a more standardized ...

Lava Dome
In volcanology, a lava dome is a circular, mound-shaped protrusion resulting from the slow extrusion of viscous lava from a volcano. Dome-building eruptions are common, particularly in convergent plate boundary settings. Around 6% of eruptions on Earth form lava domes. The geochemistry of lava domes can vary from basalt (e.g. Semeru, 1946) to rhyolite (e.g. Chaiten, 2010) although the majority are of intermediate composition (such as Santiaguito, dacite-andesite, present day). The characteristic dome shape is attributed to high viscosity that prevents the lava from flowing very far. This high viscosity can be obtained in two ways: by high levels of silica in the magma, or by degassing of fluid magma. Since viscous basaltic and andesitic domes weather fast and easily break apart by further input of fluid lava, most of the preserved domes have high silica content and consist of rhyolite or dacite. Existence of lava domes has been suggested for some domed structures on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cenozoic
The Cenozoic Era ( ; ) is Earth's current geological era, representing the last 66million years of Earth's history. It is characterized by the dominance of mammals, insects, birds and angiosperms (flowering plants). It is the latest of three geological eras of the Phanerozoic Eon, preceded by the Mesozoic and Paleozoic. The Cenozoic started with the Cretaceous–Paleogene extinction event, when many species, including the non-avian dinosaurs, became extinct in an event attributed by most experts to the impact of a large asteroid or other celestial body, the Chicxulub impactor. The Cenozoic is also known as the Age of Mammals because the terrestrial animals that dominated both hemispheres were mammalsthe eutherians ( placentals) in the Northern Hemisphere and the metatherians (marsupials, now mainly restricted to Australia and to some extent South America) in the Southern Hemisphere. The extinction of many groups allowed mammals and birds to greatly diversify so that large m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhyolite
Rhyolite ( ) is the most silica-rich of volcanic rocks. It is generally glassy or fine-grained (aphanitic) in texture (geology), texture, but may be porphyritic, containing larger mineral crystals (phenocrysts) in an otherwise fine-grained matrix (geology), groundmass. The mineral assemblage is predominantly quartz, sanidine, and plagioclase. It is the extrusive equivalent of granite. Its high silica content makes rhyolitic magma extremely viscosity, viscous. This favors explosive eruptions over effusive eruptions, so this type of magma is more often erupted as pyroclastic rock than as lava flows. Rhyolitic ash-flow tuffs are among the most voluminous of continental igneous rock formations. Rhyolitic tuff has been used extensively for construction. Obsidian, which is rhyolitic volcanic glass, has been used for tools from prehistoric times to the present day because it can be shaped to an extremely sharp edge. Rhyolitic pumice finds use as an abrasive, in concrete, and as a soil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carcross, Yukon
Carcross, originally known as Caribou Crossing, () is an unincorporated community in Yukon, Canada, on Bennett Lake and Nares Lake. It is home to the Carcross/Tagish First Nation. It is south-southeast by the Alaska Highway and the Klondike Highway from Whitehorse. The south end of the Tagish Road is in Carcross. Carcross is also on the White Pass and Yukon Route railway. Carcross is mainly known for its world class mountain biking on the near-by Montana Mountain, and for the nearby Carcross Desert, often referred to as the "world's smallest desert." History Caribou Crossing was a fishing and hunting camp for Inland Tlingit and Tagish people. 4,500-year-old artifacts from First Nations people living in the area have been found in the region. Originally known as ''Naataase Heen'' (Tagish for ‘water running through the narrows’), Caribou Crossing was named after the migration of huge numbers of caribou across the natural land bridge between Lake Bennett and Nares Lake.

Mount Skukum
The Mount Skukum Volcanic Complex is an early Eocene caldera complex, located 43 km west of Carcross and 32 km northeast of Mount Porsild in the Yukon Territory, Canada. The complex composes the Skukum Group. It is a northeast-trending complex of subaerial volcanic and volcaniclastic rocks covering 140 km2.
