A small handmade booklet about St. Mark's Episcopal Mission and boarding school, Tortella Hall in Nenana, Alaska. Original photographs illustrate the booklet and hand written and typed notations explain the contents. The book describes the Mission's work and the school that housed and instructed twenty-eight children of varying ages. Among the Athabascan children and youth pictured is Walter Harper, who was with Archdeacon Hudson Stuck on the 1913 ascent of Mount McKinley, and for whom Harper Ridge is named.
