The Tonquin Valley is located in Jasper National Park, Alberta, Canada, next to the border of the provinces of Alberta and British Columbia, an area which is also the continental divide, running along the peaks of the South Jasper Range (including The Ramparts subrange) which rise above Amethyst Lake. Tonquin Creek drains Moat Lake and flows west into Mount Robson Provincial Park in British Columbia, and empties into the Fraser River. The Astoria River drains south and east into the Athabasca River.

Jasper National Park national park in the Canadian Rockies

The Tonquin Valley leads to Tonquin Pass which cradles the Amythyst Lakes at its crest beneath the 1,000-metre (3,300 ft) Precambrian quartzite wall of the Ramparts. [1] The valley was named after the Pacific Fur Company ship Tonquin , destroyed in Clayoquot Sound in 1811.

Tonquin Pass, 1948 m (6393 ft), is a mountain pass in the Canadian Rockies, linking Tonquin Valley in Jasper National Park, Alberta, to Mount Robson Provincial Park and adjoining areas of British Columbia. It is at the headwaters of Tonquin Creek, which flows into British Columbia. Located on the interprovincial boundary, it is on the Continental Divide.

The Precambrian is the earliest part of Earth's history, set before the current Phanerozoic Eon. The Precambrian is so named because it preceded the Cambrian, the first period of the Phanerozoic eon, which is named after Cambria, the Latinised name for Wales, where rocks from this age were first studied. The Precambrian accounts for 88% of the Earth's geologic time.

Quartzite hard, non-foliated metamorphic rock which was originally pure quartz sandstone

Quartzite is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone. Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of iron oxide (Fe2O3). Other colors, such as yellow, green, blue and orange, are due to other minerals.

Recreation

Within the valley there is the scenic Amethyst Lake and Moat Lake. It is a popular destination for back-country hikers, ski touring and horseback trips to the two outfitters camps on the shores of Amethyst Lake. There are also a number of backcountry campgrounds and an Alpine Club of Canada hut.

Hiking Walking as a hobby, sport, or leisure activity

Hiking is the preferred term, in Canada and the United States, for a long, vigorous walk, usually on trails (footpaths), in the countryside, while the word walking is used for shorter, particularly urban walks. On the other hand, in the United Kingdom, and the Republic of Ireland, the word "walking" is acceptable to describe all forms of walking, whether it is a walk in the park or backpacking in the Alps. The word hiking is also often used in the UK, along with rambling, hillwalking, and fell walking. The term bushwalking is endemic to Australia, having been adopted by the Sydney Bush Walkers club in 1927. In New Zealand a long, vigorous walk or hike is called tramping. It is a popular activity with numerous hiking organizations worldwide, and studies suggest that all forms of walking have health benefits.

The 1928 High Trip of the Sierra Club took place in this area. Among those who participated was photographer Ansel Adams and Sierra Club director William Colby.

Two trails into the valley are utilized by outfitters, skiers and hikers alike. There is the Portal Creek access, and the Astoria River access trails. Unbeknownst to many is the older and unused access via the Meadow Creek trail. This trail is considered impassable as it has not been maintained for decades. Some portions of the current trail are visible in Google Earth.

Wildlife

The valley is a frequent locale for grizzly bears, cougars and elk during the summer months as well as mountain caribou, and other Rocky Mountain Wildlife. The lakes are home to an introduced, and stable populations of rainbow trout and brook trout.

Rainbow trout fresh-water species of fish

The rainbow trout is a trout and species of salmonid native to cold-water tributaries of the Pacific Ocean in Asia and North America. The steelhead is an anadromous (sea-run) form of the coastal rainbow trout(O. m. irideus) or Columbia River redband trout (O. m. gairdneri) that usually returns to fresh water to spawn after living two to three years in the ocean. Freshwater forms that have been introduced into the Great Lakes and migrate into tributaries to spawn are also called steelhead.

Brook trout species of fish

The brook trout is a species of freshwater fish in the char genus Salvelinus of the salmon family Salmonidae. It is native to Eastern North America in the United States and Canada, but has been introduced elsewhere in North America, as well as to Iceland, Europe, and Asia. In parts of its range, it is also known as the eastern brook trout, speckled trout, brook charr, squaretail, or mud trout, among others. A potamodromous population in Lake Superior, as well as an anadromous population in Maine, is known as coaster trout or, simply, as coasters. The brook trout is the state fish of nine U.S. states: Michigan, New Hampshire, New Jersey, New York, North Carolina, Pennsylvania, Vermont, Virginia, and West Virginia, and the Provincial Fish of Nova Scotia in Canada.

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–United States 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.
