This student activity introduces students to the concept of repatriation of cultural heritage items to the tribes to whom they belong, and the ways that museums and Native American groups are now using 3D technology to aid in the process. A killer whale hat, or kéet-s'aaxw, was requested to be repatriated by members of the Tlingit tribe. The Smithsonian Institution, under the repatriation provisions of the National Museum of the American Indian Act, did so. In the years following, the clan's leader decided that it might be beneficial to 3D scan the image in order to preserve its details and protect it in case of loss or fire. Having this data allowed the museum to create an accurate replica to be used for educational purposes, and provided the tribe with peace of mind.
