Aleutian boy

Great story about an Aleut boy living on a remote island in the Aleutians who is joined by a White boy from Anchorage. They go on a fishing trip in a skiff, but confront some good 'ole Aleutian weather, ending up marooned on an uninhabited island. In order to survive, the boys have to learn how to construct shelter and how to forage for food. They dig down into the earth, locating stone artifacts. They build an ulux (semi-subterranean dwelling also known by the Russian word "barabara"). They eventually build an iqyax (sea kayak also known by the Russian name "baidarka") and paddle back to civilization.
