The Quesnel Highland is a geographic area in the Central Interior of the Canadian province of British Columbia. [1] As defined by BC government geographer in Landforms of British Columbia, an account and analysis of British Columbia geography that is often cited as authoritative, the Highland is a complex of upland hill and plateau areas forming and defined as being the buffer between the Cariboo Plateau and the Cariboo Mountains, as a sort of highland foothills along the eastern edge of the Interior Plateau running southeast from a certain point southeast of the city of Prince George to the Mahood Lake area at the southeast corner of the Cariboo. [2] Beyond Mahood Lake lies another separately classified area dubbed by Holland the Shuswap Highland which spans similar terrain across the North Thompson and Shuswap Lake-Adams River drainage basins, forming a similar upland-area buffer between the Thompson Plateau and the Monashee Mountains. A third area, the Okanagan Highland, extends from the southern end of the Shuswap Highland in the area of Vernon and Enderby in the northern Okanagan region into Washington State, and also abuts the Monashee Mountains .
The boundary of the Quesnel Highland is not precisely defined in Holland, and in some interpretations it may be considered to be part of the Interior Plateau, as Holland defines it, or as a subrange of the Cariboo Mountains. Those mountains also, in some reckonings, are classified as part of the Interior Plateau rather than their usual association as the northernmost subrange of the Columbia Mountains. Generally it is composed of the lower, westerly valleys of Horsefly Lake, Quesnel Lake, and the Bowron Lakes, most of the Cariboo goldfield towns and similar terrain northwestwards, to about where the Willow River rounds the northern end of the Cariboo Mountains to join the Fraser River.
The Monashee Mountains are a mountain range lying mostly in British Columbia, Canada, extending into the U.S. state of Washington. They stretch 530 km (329 mi) from north to south and 150 km (93 mi) from east to west. They are a sub-range of the Columbia Mountains. The highest summit is Mount Monashee, which reaches 3,274 m (10,741 ft). The name is from the Scottish Gaelic monadh and sìth, meaning "moor" and "peace".
The Columbia Mountains are a group of mountain ranges along the Upper Columbia River in British Columbia, Montana, Idaho and Washington. The mountain range covers 135,952 km². The range is bounded by the Rocky Mountain Trench on the east, and the Kootenai River on the south; their western boundary is the edge of the Interior Plateau. Seventy-five percent of the range is located in Canada and the remaining twenty-five percent in the United States; American geographic classifications place the Columbia Mountains as part of the Rocky Mountains complex, but this designation does not apply in Canada. Mount Sir Sandford is the highest mountain in the range, reaching 3,519 metres (11,545 ft).
British Columbia is the westernmost province of Canada, bordered by the Pacific Ocean. With an area of 944,735 km2 (364,764 sq mi) 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.
The Interior Plateau comprises a large region of the Interior of British Columbia, and lies between the Cariboo and Monashee Mountains on the east, and the Hazelton Mountains, Coast Mountains and Cascade Range on the west. The continuation of the plateau into the United States is known there as the Columbia Plateau.
The Cariboo Mountains are the northernmost subrange of the Columbia Mountains, which run down into the Spokane area of the United States and include the Selkirks, Monashees and Purcells. The Cariboo Mountains are entirely within the province of British Columbia, Canada. The range is 7,700 square kilometres (3,000 sq mi) in area and about 245 km in length (southeast–northwest) and about 90 km at its widest (southwest–northeast).
The Bonaparte Plateau, in British Columbia, Canada, is a sub-plateau of the Thompson Plateau which extends to the Quesnel River and lies between the Cariboo Mountains on the east and the Fraser River on the west. The Thompson Plateau is itself a sub-plateau of the larger Fraser Plateau.
The basin of the Shuswap River lies northeast of the Okanagan Valley in British Columbia, originating in the central Monashee Mountains. It is the upper part of the drainage better known to British Columbians as belonging to Shuswap Lake and the South Thompson River. The river's drainage basin is over 1,969 square kilometres (760 sq mi) in area.
The North American Cordillera, sometimes also called the Western Cordillera of North America, the Western Cordillera, or the Pacific Cordillera, is the North American portion of the American Cordillera, the mountain chain system (cordillera) along the western coast of the Americas. The North American Cordillera covers an extensive area of mountain ranges, intermontane basins, and plateaus in Western and Northwestern Canada, Western United States, and Mexico, including much of the territory west of the Great Plains.
The Okanagan Highland is an elevated hilly plateau area in British Columbia, Canada, and the U.S. state of Washington. Rounded mountains with elevations up to 8,000 ft (2,400 m) above sea level and deep, narrow valleys are characteristic of the region.
The Thompson Plateau forms the southern portion of the Interior Plateau of British Columbia, Canada, lying to the west of Okanagan Lake, south of the Thompson River and east of the Fraser River. At its most southern point the plateau is squeezed by the mountainous terrain of the Cascade Range abutting closer to the Okanagan Valley. Its southwestern edge abuts the Canadian Cascades portion of that extensive range, more or less following the line of the Similkameen River, its tributary the Tulameen River, and a series of passes from the area of Tulameen, British Columbia to the confluence of the Thompson River with the Nicoamen River, a few kilometres (miles) east of Lytton, British Columbia, which is in the Fraser Canyon. Its northeastern edge runs approximately from the city of Vernon, British Columbia through the valley of Monte Creek to the junction of the same name just east of the city of Kamloops. Northeast of that line is the Shuswap Highland.
The Nechako Plateau is the northernmost subdivision of the Interior Plateau, one of the main geographic regions of the Canadian province of British Columbia. It spans the basin of the Nechako River and its tributaries the Stuart River and Endako Rivers, and is bounded on the south by the West Road River, south of which is the Chilcotin Plateau and on the north by the Nation River and the valleys of Babine and Takla Lakes, beyond which are the Omineca Mountains (N) and Skeena Mountains (NW). To the west, it abuts the various ranges of the Hazelton Mountains while on its east it is bounded by the pass between Prince George, British Columbia and the Parsnip Arm of Williston Lake, beyond which is the McGregor Plateau, which skirts the Northern Rockies. Some classification systems include the plateau area on the east bank of the Fraser River beyond the city of Prince George; this area neighbours the northernmost reaches of the Quesnel Highland and Cariboo Mountains.
The British Columbia Interior, popularly referred to as the BC Interior or simply the Interior, is a geographic region of the Canadian province of British Columbia. While the exact boundaries are variously defined, the British Columbia Interior is generally defined to include the 14 regional districts that do not have coastline along the Pacific Ocean or Salish Sea, and are not part of the Lower Mainland. Other boundaries may exclude parts of or even entire regional districts, or expand the definition to include the regional districts of Fraser Valley, Squamish–Lillooet, and Kitimat–Stikine.
The Shuswap Highland is a plateau-like hilly area of 14,511 km2 (5,603 sq mi) in British Columbia, Canada. It spans the upland area between the Bonaparte and Thompson Plateaus from the area of Mahood Lake, at the southeast corner of the Cariboo Plateau, southeast towards the lower Shuswap River east of Vernon in the Okanagan.
The Gold Range is a subrange of the Monashee Mountains in the southern British Columbia Interior. This range originally applied to all of the Monashees between the Arrow Lakes and the Okanagan but today only applies to a narrow stretch of the Monashee Mountains' eastern flank adjoining Upper Arrow Lake, west of the upper Shuswap River.
Thompson Country, also referred to as The Thompson and sometimes as the Thompson Valley and historically known as the Couteau Country or Couteau District, is a historic geographic region of the Southern Interior of British Columbia, more or less defined by the basin of the Thompson River. This is a tributary of the Fraser; the major city in the area is Kamloops.
The Fraser Plateau is an intermontane plateau. It is one of the main subdivisions of the Interior Plateau located in the Central Interior of British Columbia.
The Sawtooth Range is a subrange of the Shuswap Highland area of the central Monashee Mountains in the Southern Interior of British Columbia, Canada. It is located between Mabel Lake (W) and Sugar Lake (E) and bounded on the south by the upper Shuswap River. Its northern boundary is just south of the Three Valley Gap area of Eagle Pass, which is the route of the Canadian Pacific Railway mainline and the Trans-Canada Highway. To the east, across the uppermost Shuswap River above Sugar Lake, is the Gold Range of the main spine of the Monashees, to which it is connected by the col of Joss Pass. To the west, it is adjoined by the rest of the Shuswap Highland, of which it is a part and is an intermediary mountainous plateau between the Monashees and the northeastern Thompson Plateau.
Mount Tod commonly known as Tod Mountain, is a summit 50 km northeast of Kamloops, British Columbia, Canada. Located northeast of the junction of Louis and McGillivray Creeks, it is part of the upland area between the Interior Plateau (W) and the Monashee Mountains (E) known as the Shuswap Highland, the mountain is the highest of three summits comprising the Sun Peaks alpine ski resort.
The Kootenay Land District is a cadastral survey subdivision of the province of British Columbia, Canada, created with rest of those on Mainland British Columbia via the Lands Act of the Colony of British Columbia in 1860. The British Columbia government's BC Names system, a subdivision of GeoBC, defines a land district as "a territorial division with legally defined boundaries for administrative purposes" All land titles and surveys use the Land District system as the primary point of reference, and entries in BC Names for placenames and geographical objects are so listed.
