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.
[1] The valley was named after the Pacific Fur Company ship Tonquin, destroyed in Clayoquot Sound in 1811.
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.
Among those who participated was photographer Ansel Adams and Sierra Club director William Colby.
