Plateau An area of a highland, usually of relatively flat terrain

In geology and physical geography, a plateau, also called a high plain or a tableland, is an area of a highland, usually consisting of relatively flat terrain, that is raised significantly above the surrounding area, often with one or more sides with steep slopes. Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, and erosion by water and glaciers. Plateaus are classified according to their surrounding environment as intermontane, piedmont, or continental.

British Columbia Province of Canada

Canada Country in North America

Canada is a country in the northern part of North America. Its ten provinces and three territories extend from the Atlantic to the Pacific and northward into the Arctic Ocean, covering 9.98 million square kilometres, making it the world's second-largest country by total area. Canada's southern border with the United States is the world's longest bi-national land border. Its capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. As a whole, Canada is sparsely populated, the majority of its land area being dominated by forest and tundra. Consequently, its population is highly urbanized, with over 80 percent of its inhabitants concentrated in large and medium-sized cities, many near the southern border. Canada's climate varies widely across its vast area, ranging from arctic weather in the north, to hot summers in the southern regions, with four distinct seasons.

Geography of British Columbia

British Columbia is the westernmost province of Canada, bordered by the Pacific Ocean. With an area of 944,735 square kilometres (364,764 sq mi) it is Canada's third-largest province. The province is almost four times the size of United Kingdom, two and one-half times larger than Japan and larger than every U.S. 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 Liard Plain is a landform in far northern British Columbia, Canada. It is located between the Smith River and the Dease Plateau.

The Liard River flows through Yukon, British Columbia and the Northwest Territories, Canada. Rising in the Saint Cyr Range of the Pelly Mountains in southeastern Yukon, it flows 1,115 kilometres (693 mi) southeast through British Columbia, marking the northern end of the Rocky Mountains and then curving northeast back into Yukon and Northwest Territories, draining into the Mackenzie River at Fort Simpson, Northwest Territories. The river drains approximately 277,100 square kilometres (107,000 sq mi) of boreal forest and muskeg.

Quesnel Highland mountain in Canada

The Quesnel Highland is a geographic area in the Central Interior of the Canadian province of British Columbia. 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. 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 Horseranch Range is a 40 km (25 mi) long north-south trending mountain range in northern British Columbia, Canada, located at the head of the Red River to the northwest of Deadwood Lake. Part of the Dease Plateau of the Cassiar Mountains system, it contains no glaciers and lies completely above tree line.

The Dease Plateau is a subregion of the larger Yukon Plateau, and is located in far northern British Columbia, Canada, northwest from the Deadwood River to and beyond the Yukon-British Columbia boundary. The plateau is named in association with Dease Lake and the Dease River. Very mountainous in some of its vast area, it is in some classification systems it is included as a subarea of the Cassiar Mountains.

The Jennings River is a river in far northern British Columbia, Canada, rising in the northern reaches of the Stikine Ranges of the Cassiar Mountains, at first running southwest, then turning northeast near the Tuya Range to enter Teslin Lake at its southern end, just to the east of the estuary of the Teslin River; also joining the lake in the same area is the Hayes River. The lower reaches of the Jennings form the boundary of the Nisutlin Plateau, which extends north into the Yukon along the eastern flank of Teslin Lake and to the west of the northernmost reaches of the Stikine Ranges; Simpson Peak is one of the few named summits in that region of the Stikines, and stands above the lower Jennings to the east of its estuary. To the south of the Jennings, west of the Tuya Range, is the Kawdy Plateau, which includes the small but rugged Atsutla Range, and southwest of which is the course of the Teslin River, which traverses the Kawdy, a subset of the Stikine Plateau, from south to north.

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
