Agostini's 1928 film Patagonia documents the daily lives of the three native groups who inhabited Tierra del Fuego between Chile and southern Argentina: the Onas, the Alacalufes, and the Tehuelches. Featuring life amidst a rough terrain of rocky ice-capped mountains, majestic glaciers, and thunderous rapids, the film presents an early record of their hunting methods, healing rituals, clothes and basket making and way of life. Alberto also shows the colonization of Tierra del Fuego, from a rocky frigid terrain into an area with newly paved roads and agricultural productivity.
