Iturralde Crater (also called Araona Crater) is an 8-kilometre (5.0 mi) diameter circular geophysical feature in Madidi National Park in the Bolivian portion of the Amazon Rainforest, first identified from Landsat satellite imagery in 1985. The structure is located in a remote area in the Abel Iturralde Province of La Paz Department and was visited by researchers in 2002. Based on the presence of millions of glass beads, it has been hypothesised that the structure was created in the Late Pleistocene (between 30,000 and 11,000 years ago) by the air burst of a non-impacting meteorite, similar to the Tunguska event in 1908.
