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.
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.
