The colorado river flood of 1914: Groeber’s first geological contribution since his arrival in Argentina
It is analyzed the report made by Pablo Groeber a few months after the catastrophic collapse of the Carri Lauquén paleolake developed in 1914 in the Main Cordillera between Mendoza and Neuquén. He presented the topographic survey of the area occupied by the paleolake, analyzed the causes of its form...
