“Yuungnaqpiallerput (The Way We Genuinely Live): Masterworks of Yup’ik Science and Survival” is a fascinating and informative (and large!) website companion to a 2008 exhibition by the same name at the Anchorage Museum. Books and catalogues are also available and look to be excellent.
I know that Yup’ik territory, on the southern flanks of the Bering Straits, is a long way from the Northwest Coast. But there are many similarities in the ingenious tricks and tools of the trade needed for a maritime lifestyle, and this exhibition deftly combines historical, archaeological and ethnographic accounts into a compelling vision of people at ease on land and sea.
