Sifton Pass, 1,012 metres (3,320 feet), [1] is a mountain pass in the Rocky Mountain Trench in the Northern Interior of British Columbia, Canada, forming the divide between the Fox and Kechika Rivers, [2] and therefore between the drainage basins of the Finlay (the north fork of the Peace) and Liard Rivers. It also forms a division point between the Muskwa Ranges of the Northern Rockies to its east, and the Cassiar Mountains to its west.
It forms the prominence col for Thudaka Peak, many miles distant and the main height of land in the Interior Mountains between the Trench and the Boundary Ranges of the Coast Mountains. The resulting prominence for Thudaka is 1763 m, with the line parent for that peak being Mount Lloyd George, one of the highest in the Muskwa Ranges.
It was named for Clifford Sifton, [3] : 243
The Rocky Mountains, also known as the Rockies, are a major mountain range and the largest mountain system in North America. The Rocky Mountains stretch 3,000 miles in straight-line distance from the northernmost part of Western Canada, to New Mexico in the Southwestern United States. Depending on differing definitions between Canada and the U.S., its northern terminus is located either in northern British Columbia's Terminal Range south of the Liard River and east of the Trench, or in the northeastern foothills of the Brooks Range/British Mountains that face the Beaufort Sea coasts between the Canning River and the Firth River across the Alaska-Yukon border. Its southernmost point is near the Albuquerque area adjacent to the Rio Grande rift and north of the Sandia–Manzano Mountain Range. Being the easternmost portion of the North American Cordillera, the Rockies are distinct from the tectonically younger Cascade Range and Sierra Nevada, which both lie farther to its west.
The Canadian Rockies or Canadian Rocky Mountains, comprising both the Alberta Rockies and the British Columbian Rockies, is the Canadian segment of the North American Rocky Mountains. It is the easternmost part of the Canadian Cordillera, which is the northern segment of the North American Cordillera, the expansive system of interconnected mountain ranges between the Interior Plains and the Pacific Coast that runs northwest–southeast from central Alaska to the Isthmus of Tehuantepec in Mexico.
Mount Columbia is a mountain located in the Winston Churchill Range of the Rocky Mountains. It is the highest point in Alberta, Canada, and is second only to Mount Robson for height and topographical prominence in the Canadian Rockies. It is located on the border between Alberta and British Columbia on the northern edge of the Columbia Icefield. Its highest point, however, lies within Jasper National Park in Alberta.
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 Rocky Mountain Trench, also known as the Valley of a Thousand Peaks or simply the Trench, is a large valley on the western side of the northern part of North America's Rocky Mountains. The Trench is both visually and cartographically a striking physiographic feature extending approximately 1,600 km (1,000 mi) from Flathead Lake, Montana, to the Liard River, just south of the British Columbia–Yukon border near Watson Lake, Yukon. The trench bottom is 3–16 km (1.9–9.9 mi) wide and is 600–900 m (2,000–3,000 ft) above sea level. The general orientation of the Trench is an almost straight 150/330° geographic north vector and has become convenient as a visual guide for aviators heading north or south.
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.
The Kechika River is a tributary of the Liard River, about 300 kilometres (190 mi) long, in northern British Columbia, Canada. The Kechika flows generally northwest through the northernmost section of the Rocky Mountain Trench before turning east to join the Liard, a major branch of the Mackenzie River system. The river's 22,700 km2 (8,800 sq mi) drainage basin is characterized by high glaciated peaks, boreal forest, and open tundra. With no settlements, roads or dams along its course, the Kechika is considered "one of British Columbia's finest examples of wilderness and undisturbed wildlife habitat."
The Muskwa Ranges are a group of mountain ranges in northern British Columbia, Canada. They are part of the Northern Rockies section of the Rocky Mountains and are bounded on their west by the Rocky Mountain Trench and on their east by the Rocky Mountain Foothills. They are delimited on the north by the Liard River and on the south by the Peace Reach of the Lake Williston reservoir, south of which the next major grouping of the Rockies is the Hart Ranges.
The Omineca Mountains, also known as "the Ominecas", are a group of remote mountain ranges in the Boreal Cordillera of north-central British Columbia, Canada. They are bounded by the Finlay River on the north, the Rocky Mountain Trench on the east, the Nation Lakes on the south, and the upper reaches of the Omineca River on the west. They form a section of the Continental Divide, that, in this region, separates water drainage between the Arctic and Pacific Oceans. The lower course of the Omineca River flows through the heart of the range. To the south of the Ominecas is the Nechako Plateau, to the west the Skeena Mountains and Hazelton Mountains, to the north the Spatsizi Plateau and the Stikine Ranges, while east across the Rocky Mountain Trench are the Muskwa Ranges.
The Cassiar Mountains are the most northerly group of the Northern Interior Mountains in the Canadian province of British Columbia and also extend slightly into the southernmost Yukon Territory. They lie north and west of the Omineca Mountains, west of the northernmost Rockies and the Rocky Mountain Trench, north of the Hazelton Mountains and east of the Boundary Ranges. They form a section of the Continental Divide, that, in this region, separates water drainage between the Arctic and Pacific Oceans. Physiographically, they are a section of the larger Yukon-Tanana Uplands province, which in turn are part of the larger Intermontane Plateaus physiographic division.
The Stikine Ranges are a group of mountain ranges and mountainous plateaus in northwestern British Columbia, Canada. They are the northernmost subdivision of the Cassiar Mountains and among the least explored and most undeveloped parts of the province.
The Thudaka Range is a mountain range located east of the Rocky Mountain Trench in British Columbia, Canada bounded by the Obo River on the east, the Frog River on the west, and on the south by the pass between Geese and Thudaka Creeks. The highest peak in the range is Thudaka Peak at 2,748 m (9,016 ft). The range is part of the Stikine Ranges.
The Sifton Ranges are a mountain range along the west side of the Rocky Mountain Trench in northern British Columbia, Canada. It has an area of 1823 km2 and is a subrange of the Cassiar Mountains which in turn form part of the Interior Mountains.
Thudaka Peak is the highest mountain of the Thudaka Range of the Cassiar Mountains in the Northern Interior of British Columbia, Canada, located between the heads of Obo River and Frog River. Glaciers exist on Thudaka's northern flanks, but the zone is usually quite dry.
Mount Ulysses, is the highest mountain in the Muskwa Ranges of the Northern Canadian Rockies in British Columbia. It and neighbouring peaks are part of a group of names drawing on the epic poem The Odyssey, in which here Ulysses wanders for 10 years before being able to return home to Ithaca.
Constable Peak is a 2,824-metre (9,265 ft) peak in British Columbia, Canada, rising to a prominence of 844 metres (2,769 ft) above Racing-Tuchodi Pass. Its line parent is King Peak, 15 kilometres (9.3 mi) away. It is part of the Tower of London Range of the Muskwa Ranges in the Canadian Rockies.
Dieppe Mountain is a 2,863-metre (9,393 ft) peak in British Columbia, Canada, rising to a prominence of 1,058 metres (3,471 ft) above Gataga Pass. Its line parent is Tuchodi Peak, 55 kilometres (34 mi) away. It is part of the Northern Rocky Mountains. The mountain is located West of the junction of Racing River and Delano Creek and SW of Fort Nelson. Dieppe Mountain is named for the World War II Dieppe Raid that involved Canadian troops which took place on 19 August 1942.
Mount Lloyd George is a 2,938-metre (9,639 ft) peak in British Columbia, Canada, rising to a prominence of 1,208 metres (3,963 ft) above Lloyd George Pass. The mountain is located NE of Haworth Lake in Kwadacha Wilderness Provincial Park. Its line parent is Mount Sylvia, 37 kilometres (23 mi) away. It is part of the Northern Rocky Mountains.
The Battle of Britain Range is a group of mountains within the Allies Group of the Muskwa Ranges in northern British Columbia, Canada. The Muskwa Ranges also include the Tower of London Range, Italy Range and Allied Leaders Range.
The Tuchodi River is a stream in the Northern Rocky Mountains of northern British Columbia, Canada. The river flows through the Northern Rocky Mountains Provincial Park in a northeasterly direction to the Muskwa River. Its name comes from Slavey words that mean "place of large water", probably a reference to the two lakes where the river widens.
