    Archaeological Survey of Canada

    The Archaeological Survey of Canada (ASC) was established in 1971. It is the division of the Canadian Museum of History that deals with the archaeological heritage of Canada. The major goals of the ASC are to preserve archaeological sites, research into the history of Canadian Indigenous peoples and present the results of archaeological research to the public, through publications and exhibitions. The ASC’s Mercury Series of monographs is one of the main outlets for the reporting of archaeological research in the country. Its exhibitions, both in the Canadian Museum of History and smaller ones that travel across the country, enhance public understanding of the traditions of the Indigenous peoples of Canada. (See also Archaeology.)

    Burgess Shale

    Burgess Shale is an area of layered rock featuring fossils from the middle of the Cambrian period (505–510 million years ago). In Canada, sites featuring Burgess Shale fossils are found in Yoho and Kootenay national parks. The name “Burgess” comes from Mount Burgess, a peak in Yoho National Park near where the original Burgess Shale site was discovered (the mountain is in turn named for Alexander Burgess, an early deputy minister of the Department of the Interior). Burgess Shale sites are the clearest record of Cambrian marine life because they contain rare fossils of soft-bodied organisms. The original Burgess Shale site is one of the reasons seven parks in the area were designated the Canadian Rocky Mountains UNESCO World Heritage site (the parks are Yoho, Jasper, Banff and Kootenay national parks, and Mount Robson, Mount Assiniboine and Hamber provincial parks).
