The Coast Mountains are a major mountain range in the Pacific Coast Ranges of western North America, extending from southwestern Yukon through the Alaska Panhandle and virtually all of the Coast of British Columbia south to the Fraser River. The mountain range's name derives from its proximity to the sea coast, and it is often referred to as the Coast Range. The range includes volcanic and non-volcanic mountains and the extensive ice fields of the Pacific and Boundary Ranges, and the northern end of the volcanic system known as the Cascade Volcanoes. The Coast Mountains are part of a larger mountain system called the Pacific Coast Ranges or the Pacific Mountain System, which includes the Cascade Range, the Insular Mountains, the Olympic Mountains, the Oregon Coast Range, the California Coast Ranges, the Saint Elias Mountains and the Chugach Mountains. The Coast Mountains are also part of the American Cordillera—a Spanish term for an extensive chain of mountain ranges—that consists of an almost continuous sequence of mountain ranges that form the western backbone of North America, Central America, South America and Antarctica.
Bennett Lake is a lake in the Province of British Columbia and Yukon Territory in northwestern Canada, at an elevation of 656 m (2,152 ft). It is just north of the border with the United States state of Alaska, near the Alaskan port of Skagway. The lake has an area of either 90.68 or 96.8 km2. The average depth is 61.9 m (203 ft) and the maximum depth is 123 m (404 ft).
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 Boundary Ranges, also known in the singular and as the Alaska Boundary Range, are the largest and most northerly subrange of the Coast Mountains. They begin at the Nass River, near the southern end of the Alaska Panhandle in the Canadian province of British Columbia and run to the Kelsall River, near the Chilkoot Pass, beyond which are the Alsek Ranges of the Saint Elias Mountains, and northwards into the Yukon Territory flanking the west side of the Yukon River drainage as far as Champagne Pass, north of which being the Yukon Ranges. To their east are the Skeena Mountains and Stikine Plateau of the Interior Mountains complex that lies northwest of the Interior Plateau; the immediately adjoining subregion of the Stikine Plateau is the Tahltan Highland. To their northeast is the Tagish Highland, which is a subregion of the Yukon Plateau. Both highlands are considered in some descriptions as included in the Coast Mountains. The Alexander Archipelago lies offshore and is entirely within Alaska.
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 along the Pacific 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.
Atlin is a community in northwestern British Columbia, Canada, located on the eastern shore of Atlin Lake. In addition to continued gold-mining activity, Atlin is a tourist destination for fishing, hiking and heliskiing. As of 2016, there are 477 permanent residents.
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 Skeena Mountains, also known as the Skeenas, are a subrange of the Interior Mountains of northern British Columbia, Canada, essentially flanking the upper basin of the Skeena River. They lie just inland from the southern end of the Boundary Ranges of the Coast Mountains, and also of the northern end of the Kitimat Ranges. Their southern limit is described by the Bulkley River and the upper northwestern reaches of Babine and Takla Lakes, and on their northeast by the upper reaches of the Omineca River.
The Hazelton Mountains are a grouping of mountain ranges on the inland lee of the Kitimat Ranges of the Coast Mountains in northwestern British Columbia, Canada, spanning the area of Hazelton south to the Nechako Reservoir. Defined by the British Columbia geographic names office, they span from the Nass River to the Nechako Plateau, and between the Coast Mountains and the Bulkley River, they are considered by geographers to be part of the Interior Mountains complex, though in local perspective they are considered to be part of the Coast Mountains. They are neighboured on the west by the Kitimat Ranges and on the east by the southernmost section of the Skeena Mountains; beyond the Nass River, which is their northern boundary, are the Boundary Ranges of the Coast Mountains. To their southeast is the Nechako Plateau, including the Quanchus Range on the near-island between Ootsa and Eutsuk Lakes of the Nechako Reservoir.
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 Interior Mountains or Northern Interior Mountains are the semi-official names for an expansive collection of mountain ranges that comprises much of the northern half of the Canadian province of British Columbia and a large area of southern Yukon.
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 Stikine Plateau is a plateau in northern British Columbia, Canada. It lies between the Boundary Ranges of the Coast Mountains on the west and southwest and the Cassiar Mountains along its northeast, and between the Skeena Mountains on its south and southeast and the Jennings and Nakina Rivers on the north.
The McGregor Plateau is a sub-plateau of the Nechako Plateau, the northernmost major subdivision of the Interior Plateau spanning the inland regions of the Pacific Northwest. Located in British Columbia, Canada, to the east of the city of Prince George, British Columbia, the McGregor Plateau lies between the main spine of the Northern Rocky Mountains on the east and the Fraser River on the west, beginning on its southeast at the confluence of the Torpy River with the Fraser and running northwest, parallel to the Fraser and the Rockies, to end in the area of the Arctic and Pacific Lakes to the north of the great bend in the Fraser River just upstream from and to the northeast of Prince George. The McGregor Plateau is very mountainous in character and includes several large rivers, the largest being the McGregor River and Herrick Creek. Included in the McGregor Plateau is the McGregor Range, which lies between the McGregor and Torpy Rivers and the Dezaiko Range, which lies between Herrick and McGregor Rivers.
The Dease Plateau is a sub-plateau 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 Yukon Plateau is a plateau located in the Yukon Territory, comprising much of the central and southern Yukon Territory and the far northern part of British Columbia, Canada between Tagish Lake (W) and the Cassiar Mountains (E) and north of the Nakina River.
The White Range is a subrange of the Tagish Highland, located east of Windy Arm on the British Columbia-Yukon border in Canada.
The Taku Plateau is a sub-plateau of the Stikine Plateau in the far northwestern Interior of British Columbia, Canada. It lies to the south of the Teslin Plateau, part of the Yukon Plateau and to the southeast of the Yukon Plateau's other major sub-area within British Columbia, the Tagish Highland. Immediately northeast is the Kawdy Plateau and to the northwest of the Nahlin Plateau. The Inklin River forms the plateau's southwestern boundary with the northwestern extremities of the Tahltan Highland, beyond which are the Boundary Ranges. Very mountainous, its highest summit is Nahlin Mountain.
