McGregor Pass

Last updated

McGregor Pass, 1,555 metres (5,102 ft), [1] is a mountain pass located on the Continental Divide in the Canadian Rockies and near the head of the McGregor River, to the north of Wishaw Mountain [2] and to the west of Kakwa Pass, which is in the same vicinity. McGregor Pass forms the division between the Hart Ranges of the Rockies, which begin at Mount Sir Alexander just to the northwest and extend to the Peace Reach of Lake Williston, and the Continental Ranges, the largest and most well-known segment of the Canadian Rockies, which extend to Marias Pass, at the head of the North Fork Flathead River in Montana, United States.

Mountain pass Route through a mountain range or over a ridge

A mountain pass is a navigable route through a mountain range or over a ridge. Since many of the world's mountain ranges have presented formidable barriers to travel, passes have played a key role in trade, war, and both human and animal migration throughout Earth's history. At lower elevations it may be called a hill pass. The highest vehicle-accessible pass in the world appears to be Mana Pass, located in the Himalayas on the border between India and Tibet, China.

Continental Divide of the Americas principal hydrological divide of North and South America

The Continental Divide is the principal, and largely mountainous, hydrological divide of the Americas. The Continental Divide extends from the Bering Strait to the Strait of Magellan, and separates the watersheds that drain into the Pacific Ocean from those river systems that drain into the Atlantic Ocean and, along the northernmost reaches of the Divide, those river systems that drain into the Arctic Ocean.

Canadian Rockies mountain range in Canada

The Canadian Rockies or Canadian Rocky Mountains comprise the Canadian segment of the North American Rocky Mountains. They are the eastern part of the Canadian Cordillera, which is a system of multiple ranges of mountains which runs from the Canadian Prairies to the Pacific Coast. The Canadian Rockies mountain system comprises the southeastern part of this system, lying between the Interior Plains of Alberta and Northeastern British Columbia on the east to the Rocky Mountain Trench of BC on the west. The southern end borders Idaho and Montana of the United States. In geographic terms the boundary is at the Canada/US border, but in geological terms it might be considered to be at Marias Pass in northern Montana. The northern end is at the Liard River in northern British Columbia.

McGregor Pass is the prominence col for Mount Buchanan, giving it 1,181 metres (3,875 ft) of prominence. [3]

In topography, prominence measures the height of a mountain or hill's summit relative to the lowest contour line encircling it but containing no higher summit within it. It is a measure of the independence of a summit. A peak's key col is a unique point on this contour line and the parent peak is some higher mountain, selected according to various objective criteria.

Geography of Alberta

Alberta is a Canadian province. Located in Western Canada, the province has an area of 661,190 square kilometres (255,290 sq mi) and is bounded to the south by the U.S. state of Montana along 49° north for 298 kilometres (185 mi); to the east at 110° west by the province of Saskatchewan for 1,223 kilometres (760 mi); and at 60° north the Northwest Territories for 644 kilometres (400 mi). The southern half of the province borders British Columbia along the Continental Divide of the Americas on the peaks of the Rocky Mountains, while the northern half borders British Columbia along the 120th meridian west.

Clearwater River (Alberta) river in Alberta, Canada

Clearwater is a river of southern Alberta, Canada. Situated entirely in the Canadian Rockies and the Rocky Mountain foothills of Alberta, it is a glacier fed upper reach tributary of the North Saskatchewan River. The upper reach of the Clearwater has become popular for equestrian travelers due to the natural setting along the river.

Athabasca Pass

Athabasca Pass is a high mountain pass in the Canadian Rockies. It is the headwaters of the Whirlpool River, a tributary of the Athabasca River. In fur-trade days it connected Jasper House on the Athabasca River with Boat Encampment on the Columbia River.

Taseko Mountain, also known as Mount Taseko 3063 m (10049 ft), prominence: 1277 m, is one of the principal summits of the Chilcotin Ranges, part of the Pacific Ranges subdivision of the Coast Mountains of southern British Columbia. Standing just east of the Taseko Lakes, it is the highest summit between the Taseko Lakes and the Fraser River, and the highest east of the pass between the basins of the Lord and Bridge Rivers. North and east of Taseko Mountain the landscape drops off dramatically to the flat Chilcotin Plateau. Immediately west across Taseko Lake is Mount Tatlow, which has the same elevation as Taseko Mountain.

Marias Pass

Marias Pass is a high mountain pass near Glacier National Park in northwestern Montana in the United States.

Hart Ranges

The Hart Ranges are one of the main geographic subdivisions of the Canadian Rockies and are the main part of the area that is meant by the Northern Rockies, although the much larger Muskwa Ranges to the north are more deserving of that term — but also much more inaccessible and much less visited — and the Northern Rockies are generally also considered to extend at least as far south as Mount Robson, which is in the Continental Ranges. The Hart Ranges were named in honour of British Columbia Premier John Hart, as is the highway which traverses the Pine Pass in the northern part of the range, connecting the north-central Interior of the province to its Peace River District to the northeast.

Bow Range mountain

The Bow Range is a mountain range of the Canadian Rockies in Alberta and British Columbia, Canada. The range is named in associated with the Bow River and was officially adopted on March 31, 1917 by the Geographic Board of Canada.

Robson Valley valley in British Columbia, Canada

The Robson Valley is a geographic region of the Canadian province of British Columbia, comprising the section of the Rocky Mountain Trench that lies southeast of the city of Prince George following the Fraser River to the Yellowhead Pass. The name is derived from Mount Robson, which stands near the entrance to the Yellowhead Pass. Communities in the Robson Valley include the settlements of Dome Creek, Crescent Spur, Dunster, and Tête Jaune Cache, with larger population concentrations in the villages of McBride and Valemount. On a map, the Robson Valley is located immediately south of the elbow in the boundary between Alberta and British Columbia. Transportation corridors through the Robson Valley include the Canadian National Railway lines, and Highways 16 and 5.

The Northern Rocky Mountains, usually referred to as the Northern Rockies, are a subdivision of the Canadian Rockies comprising the northern half of the Canadian segment of the Rocky Mountains. While their northward limit is easily defined as the Liard River, which is the northward terminus of the whole Rockies, the southward limit is debatable, although the area of Mount Ovington and Monkman Pass is mentioned in some sources, as south from there are the Continental Ranges, which are the main spine of the Rockies forming the boundary between British Columbia and Alberta. Some use the term to mean only the area north of Lake Williston, and in reference to Northern Rocky Mountains Provincial Park, while others consider the term to extend all the way south, beyond the limit of the Hart Ranges at Mount Ovington, to McBride and Mount Robson.

Bush Pass is a mountain pass in the Canadian Rockies, on the border between the Canadian provinces of Alberta and British Columbia. it is located at the headwaters of the Valenciennes River, formerly known as the South Fork Bush River; the North Fork Bush River is now known as the Bush River.

Ashnola River river in Canada

The Ashnola River is a tributary of the Similkameen River, rising in the northeastern part of the North Cascades in Washington, United States, and flowing north into British Columbia, Canada, to join the Similkameen River about halfway along that river's course between the towns of Princeton and Keremeos.

The pass at the head of the river, which connects to the head of the Little Toba River, is the prominence col for Mount Alfred, which lies just west of the river's mouth and is the highest summit between Jervis and Toba Inlets. Above the river's lower reaches, on the east flank of Mount Alfred, is 700 meters (2,300 ft) Alfred Creek Falls, one of North America's highest.

Fraser Pass

Fraser Pass is a mountain pass in British Columbia's Rockies. Its summit is 2,015 metres above sea level.

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.
