VANCOUVER, CANADA—Archaeologist Bob Muir and his students at Simon Fraser University investigated a midden discovered by members of the K’ómoks First Nation when they dug a roasting pit for a barbecue held last year in the Comox Valley. The students uncovered shells; the well-preserved bones of deer, elk, and dogs; bone needles used for fishing; harpoon points; herring rakes; and some 80 flat pieces of stone engraved on one side. According to a report in the Comox Valley Record, the images are sometimes described as representing trees, feathers, or symbols of fertility. Similar engraved stones, known as tablets, have been found at only two other sites in the Comox Valley. Muir estimates that the tablets are about 2,000 years old. He will document and study the artifacts before they are returned to the K’ómoks First Nation. For more on archaeology in British Columbia, go to "The Edible Seascape."
