Duffey Peak
Duffey Peak is a mountain summit located in southwest British Columbia, Canada. Description Duffey Peak is part of the Joffre Group, which is a subset of the Lillooet Ranges of the Coast Mountains. It is situated east of Pemberton, and immediately northeast of Lillooet Lake. The nearest higher neighbor is Slalok Mountain, to the northeast and the two peaks are connected by Two Goat Ridge. Precipitation runoff from the peak drains into Joffre Creek and Twin One Creek, both of which are tributaries of the Lillooet River. Topographic relief is significant as the summit rises over 2,000 meters (6,560 feet) above Lillooet Lake in four kilometers (2.5 miles). The summit offers a panoramic view of the lake as well as Mount Matier, Mount Hartzell, Mount Spetch, Slalok Mountain, and Mount Taylor. Etymology The mountain is named in association with Duffey triangulation station. The toponym was officially adopted on January 23, 1979, by the Geographical Names Board of Canada ...

Lillooet Ranges
The Lillooet Ranges are the southeasternmost subdivision of the Pacific Ranges of the Coast Mountains of British Columbia. They are located between the drainage of the Lillooet River and Harrison Lake on the west and the canyon of the Fraser River on the east, and by the lowland coastal valley of that river on the south. The Lillooet Ranges are approximately 8100 square kilometres (3150 mi²) in area. The range is extremely rugged and varied in terrain, and includes some of the highest peaks in southwestern British Columbia. The highest is Skihist Mountain, , crowning the Cantilever Range in the heart of the area to the west of the community of Lytton at the confluence of the Thompson and Fraser Rivers. The northernmost subdivision of the Lillooet Ranges is the Cayoosh Range, which includes the second-highest summit in the Lillooet Ranges, an unnamed peak just south of Seton Lake and about WSW of the town of Lillooet. To the northeast of Harrison Lake, Mount Breakenr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Hartzell
Mount Hartzell is a mountain summit located in the Coast Mountains, in Joffre Lakes Provincial Park, in southwestern British Columbia, Canada. It is part of the Joffre Group, which is a subset of the Lillooet Ranges. It is situated east of Pemberton, midway between Mount Matier and Mount Spetch, each a half kilometre either side of Hartzell. The mountain's name was submitted by Karl Ricker of the Alpine Club of Canada to honor Carl A. Hartzell, an early settler and postmaster at Pemberton. The name was officially adopted on January 23, 1979, by the Geographical Names Board of Canada. Precipitation runoff from the peak drains into Joffre Creek and Twin One Creek, both tributaries of the Lillooet River. The mountain and its climate supports the Hartzell Glacier on the southeast slope, and the Matier Glacier on the northern slope. Climate Based on the Köppen climate classification, Mount Hartzell is located in a subarctic climate zone of western North America. Most weather f ...

Twin Goat Mountain
Twin Goat Mountain is a summit in British Columbia, Canada. Description Twin Goat Mountain is located east of Pemberton in the Lillooet Ranges of the Coast Mountains. Precipitation runoff from this mountain drains into tributaries of the Lillooet River. Twin Goat Mountain is more notable for its steep rise above local terrain than for its absolute elevation as topographic relief is significant with the summit rising 1,928 metres (6,325 ft) above Lillooet Lake in . The mountain's toponym was officially adopted January 23, 1979, by the Geographical Names Board of Canada. The mountain was named in association with Twin One Creek, as submitted by Karl Ricker of the Alpine Club of Canada. Climate Based on the Köppen climate classification, Twin Goat Mountain is located in the marine west coast climate zone of western North America. Most weather fronts originate in the Pacific Ocean, and travel east toward the Coast Mountains where they are forced upward by the range (oro ...

Geology Of British Columbia
The geology of British Columbia is a function of its location on the leading edge of the North American continent. The mountainous physiography and the diversity of the different types and ages of rock hint at the complex geology, which is still undergoing revision despite a century of exploration and mapping. The province's most prominent geological features are its mountain ranges, including the North American Cordillera which stretches from Southern Mexico to Alaska. Terrane theory Terrane theory was first proposed by Jim Monger of the Geological Survey of Canada and Charlie Rouse in 1971 as an explanation for a set of fusulinid fossils that were found in central British Columbia. Rather than suggest that facies changes or seaways were behind this (which were common explanations at the time), the two geologists proposed that the fossils in question had been part of an assemblage of rocks that had migrated across the Pacific Ocean to their present location. This theor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geography Of British Columbia
British Columbia is the westernmost province of Canada, bordered by the Pacific Ocean. With an area of it is Canada's third-largest province. The province is almost four times the size of the United Kingdom and larger than every United States state except Alaska. It is bounded on the northwest by the U.S. state of Alaska, directly north by Yukon and the Northwest Territories, on the east by Alberta, and on the south by the U.S. states of Washington, Idaho, and Montana. Formerly part of the British Empire, the southern border of British Columbia was established by the 1846 Oregon Treaty. The province is dominated by mountain ranges, among them the Canadian Rockies but dominantly the Coast Mountains, Cassiar Mountains, and the Columbia Mountains. Most of the population is concentrated on the Pacific coast, notably in the area of Vancouver, located on the southwestern tip of the mainland, which is known as the Lower Mainland. It is the most mountainous province of Canada. St ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orographic Lift
Orographic lift occurs when an air mass is forced from a low elevation to a higher elevation as it moves over rising terrain. As the air mass gains altitude it quickly cools down adiabatically, which can raise the relative humidity to 100% and create clouds and, under the right conditions, precipitation. Orographic lifting can have a number of effects, including precipitation, rain shadowing, leeward winds, and associated clouds. Precipitation Precipitation induced by orographic lift occurs in many places throughout the world. Examples include: * The Mogollon Rim in central Arizona * The western slope of the Sierra Nevada range in California. * The western slope of the Wasatch Range in Utah. Specifically the Little and Big Cottonwood Canyons. * The mountains near Baja California North – specifically La Bocana to Laguna Hanson. * The windward slopes of Khasi and Jayantia Hills (see Mawsynram) in the state of Meghalaya in India. * The Western Highlands of Yemen, which rece ...

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

Weather Front
A weather front is a boundary separating air masses for which several characteristics differ, such as air density, wind, temperature, and humidity. Disturbed and unstable weather due to these differences often arises along the boundary. For instance, cold fronts can bring bands of thunderstorms and cumulonimbus precipitation or be preceded by squall lines, while warm fronts are usually preceded by stratiform precipitation and fog. In summer, subtler humidity gradients known as dry lines can trigger severe weather. Some fronts produce no precipitation and little cloudiness, although there is invariably a wind shift. Cold fronts generally move from west to east, whereas warm fronts move poleward, although any direction is possible. Occluded fronts are a hybrid merge of the two, and stationary fronts are stalled in their motion. Cold fronts and cold occlusions move faster than warm fronts and warm occlusions because the dense air behind them can lift as well as push the warme ...

Subarctic Climate
The subarctic climate (also called subpolar climate, or boreal climate) is a continental climate with long, cold (often very cold) winters, and short, warm to cool summers. It is found on large landmasses, often away from the moderating effects of an ocean, generally at latitudes from 50°N to 70°N, poleward of the humid continental climates. Like other Class D climates, they are rare in the Southern Hemisphere, only found at some isolated highland elevations. Subarctic or boreal climates are the source regions for the cold air that affects temperate latitudes to the south in winter. These climates represent Köppen climate classification ''Dfc'', ''Dwc'', ''Dsc'', ''Dfd'', ''Dwd'' and ''Dsd''. Description This type of climate offers some of the most extreme seasonal temperature variations found on the planet: in winter, temperatures can drop to below and in summer, the temperature may exceed . However, the summers are short; no more than three months of the year (but at least on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Köppen Climate Classification
The Köppen climate classification divides Earth climates into five main climate groups, with each group being divided based on patterns of seasonal precipitation and temperature. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indicates a tropical rainforest climate. The system assigns a temperature subgroup for all groups other than those in the ''A'' group, indicated by the third letter for climates in ''B'', ''C'', ''D'', and the second letter for climates in ''E''. Other examples include: ''Cfb'' indicating an oceanic climate with warm summers as indicated by the ending ''b.'', while ''Dwb'' indicates a semi-Monsoon continental climate, monsoonal continental climate ...
