Megameteorite Mystery


National Geographic staffer Fabio Amador shared some news about one of our National Geographic Society/Waitt grantees, Rogelio Acevedo, a geologist from the Centro Austral de Investiggaciones Cientificas in Argentina.


In a remote region of Patagonia, enormous craters measuring up to 500 meters wide and 50 meters in depth could be evidence to a bombardment of meteorites. This meteoroid impact field, the largest in the southern hemisphere, is of extreme interest for Dr. Acevedo.


This site, call Bajada del Diablo or Devil’s Descent, contains more than one hundred impact craters spread over 400 kilometers. Curiously, no meteorites have ever been found, but Acevedo and his team will be traveling there this October in hopes to solve the mystery by studying petrographic and mineralogic marks on the rocks. We’ll be sure to update everyone when the team returns!
