Researchers Ernesto Piana of Argentina's Austral Center for Scientific Research, left, Joan Anton Barceló of the Autonomous University of Barcelona, and Ana Cristina Araújo of the Portuguese Institute of Archeology, discuss the formation of a Yamaná shell midden along the Beagle Channel in Tierra del Fuego. Because the sites are a valuable source of information on how the Yamaná survived the harsh Fueguian climate and why they disappeared, Piana hopes to study and preserve as many as possible before bulldozers arrive to build a new road along the coast of the channel.
