YUKON, CANADA—CBC News reports that archaeologist Peter Dawson of the University of Calgary and his colleagues are using a drone and a terrestrial laser scanner to create 3-D replicas of historic sites at Pauline Cove, which is located on Herschel Island, in the Beaufort Sea off Yukon’s northern coast. The sites are in danger of being destroyed by wild animals, polar tourism, and erosion. The island has lost about 65 feet of coastline in the past 20 years, Dawson explained. The sites include structures built by Inuvialuit, American whalers, Anglican missionaries, and the Northwest Mounted Police, he added. “It’s giving us a really, really good record of the outside of the buildings and the inside of the buildings and an overview of the historic settlement area,” Barbara Hogan, manager of historic sites for Yukon Tourism and Culture, said of the project. When completed, the images will be stored in an online archive with historic information for public use.
