Solitary Mountain
Solitary Mountain is a mountain in the Big Salmon Range of the Pelly Mountains in southcentral Yukon, Canada, located southwest of Faro. It is named for its isolation and is south of the Robert Campbell Highway. Solitary Mountain consists of Late Cretaceous volcanics of the Carmacks Group, a volcanic group that may have its origin from volcanism of the Yellowstone hotspot The Yellowstone hotspot is a volcanic hotspot in the United States responsible for large scale volcanism in Idaho, Montana, Nevada, Oregon, and Wyoming, formed as the North American tectonic plate moved over it. It formed the eastern Snake Riv ... some 70 million years ago. Unlike much of the Carmacks Group, the volcanics comprising Solitary Mountain are separated by the large strike-slip Teslin Fault.

Yukon
Yukon (; ; formerly called Yukon Territory and also referred to as the Yukon) is the smallest and westernmost of Canada's three territories. It also is the second-least populated province or territory in Canada, with a population of 43,964 as of March 2022. Whitehorse, the territorial capital, is the largest settlement in any of the three territories. Yukon was split from the North-West Territories in 1898 as the Yukon Territory. The federal government's ''Yukon Act'', which received royal assent on March 27, 2002, established Yukon as the territory's official name, though ''Yukon Territory'' is also still popular in usage and Canada Post continues to use the territory's internationally approved postal abbreviation of ''YT''. In 2021, territorial government policy was changed so that “''The'' Yukon” would be recommended for use in official territorial government materials. Though officially bilingual (English and French), the Yukon government also recognizes First Na ...

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 man-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 mapp ...

Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period. Climate During the Late Cretaceous, the climate was warmer than present, although throughout the period a cooling trend is evident. The tropics became restricted to equatorial regions and northern latitudes experienced markedly more seasonal climatic conditions. Geography Due to plate tectonics, the Americas were gradually moving westward, causing the Atlantic Ocean to expand. The Western Interior Seaway divided North America into eastern and western halves; Appalachia and Laramidia. India maintained a northward course towards Asia. In the Southern Hemisphere, Australia a ...

Mountain
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable ...

Faro, Yukon
Faro is a town in the central Yukon, Canada, the home of the now abandoned Faro Mine. It was the largest open-pit lead–zinc mine in the world as well as a significant producer of silver and other natural resources. The mine was built by the Ralph M. Parsons Construction Company of the United States with General Enterprises Ltd. of Whitehorse being the main subcontractor. As of 2021, the population is 440, down from its peak population of 1,652 in 1981. Faro was named after the card game of the same name. As these industries have declined over the past decade, Faro is attempting to attract ecotourism to the region to view such animals as Dall and Stone sheep. Both species of sheep almost unique to the surrounding area. Several viewing platforms have been constructed in and around the town. One unusual feature of Faro is that it has a golf course running through the main part of town. Lorne Greene, famous for his work in ''Bonanza'' and '' Lorne Greene's New Wilderness'', ...

Robert Campbell Highway
Yukon Highway 4, also known as the Robert Campbell Highway or Campbell Highway, is a road between Watson Lake, Yukon on the Alaska Highway to Carmacks, Yukon on the Klondike Highway. It is long and mostly gravel-surfaced. It serves the communities of Faro and Ross River and intersects the Canol Road near Ross River. The highway is named for Robert Campbell, a nineteenth century Hudson's Bay Company fur trader and explorer. The first portion of the Robert Campbell Highway, between Watson Lake and Miner Junction, was built in the early 1960s as part of the project to complete road access to Tungsten, Northwest Territories. The portion east and north of Miner Junction is now the only portion still known as the Nahanni Range Road :Yukon Highway 10 :''Northwest Territories, no official route number'' (maintained by mining company) The Nahanni Range Road was completed in the early 1960s from Watson Lake, Yukon along the present alignment of the Robert Campbell Highwa ...

Carmacks Group
The Carmacks Group is a Late Cretaceous volcanic group in southwest-central Yukon, Canada, located between the communities of Dawson City and Whitehorse. It consists of flood basalts, coarse volcaniclastic rocks and sandy tuffs interbedded with subordinate andesite and basaltic lava flows. It has been interpreted to be a displaced portion of the Yellowstone hotspot track that was formed 70 million years ago.

Volcanism
Volcanism, vulcanism or volcanicity is the phenomenon of eruption of molten rock (magma) onto the Earth#Surface, surface of the Earth or a solid-surface planet or moon, where lava, pyroclastics, and volcanic gases erupt through a break in the surface called a vent. It includes all phenomena resulting from and causing magma within the crust (geology), crust or Mantle (geology), mantle of the body, to rise through the crust and form volcanic rocks on the surface. Magmas, that reach the surface and solidify, form extrusive landforms. Volcanic processes Magma from the mantle or lower crust rises through the crust towards the surface. If magma reaches the surface, its behavior depends on the viscosity of the molten constituent rock (geology), rock. Viscous (thick) magma produces volcanoes characterised by explosive eruptions, while non-viscous (runny) magma produce volcanoes characterised by effusive eruptions pouring large amounts of lava onto the surface. In some cases, rising mag ...

Yellowstone Hotspot
The Yellowstone hotspot is a volcanic hotspot in the United States responsible for large scale volcanism in Idaho, Montana, Nevada, Oregon, and Wyoming, formed as the North American tectonic plate moved over it. It formed the eastern Snake River Plain through a succession of caldera-forming eruptions. The resulting calderas include the Island Park Caldera, Henry's Fork Caldera, and the Bruneau-Jarbidge caldera. The hotspot currently lies under the Yellowstone Caldera. The hotspot's most recent caldera-forming supereruption, known as the Lava Creek Eruption, took place 640,000 years ago and created the Lava Creek Tuff, and the most recent Yellowstone Caldera. The Yellowstone hotspot is one of a few volcanic hotspots underlying the North American tectonic plate; another example is the Anahim hotspot. Snake River Plain The eastern Snake River Plain is a topographic depression that cuts across Basin and Range Mountain structures, more or less parallel to North American plate ...
