Arnold Heim. A Swiss geologist in the watershed of the lake Buenos Aires / General Carrera”, Spanish, 2009. The publication copied some of the information from the above mentioned book by A. Heim, including photos of Leones valley of 1939 - 1945. It contains photos of the same areas taken in 2009. These comparative photos show no improvement of the natural ecosystem between 1939 and 2009.
