Iturralde Crater

Iturralde Crater (also Araona crater ) is a circular surface formation in the Bolivian part of the Amazon basin. The location is in a low part of the Abel Iturralde province formation with a diameter of about eight kilometers was first discovered in 1985 in Landsat satellite images. The circular surface shape is interpreted by some scholars as a possible meteorite impact craters. Because the region of the Iturralde Crater is located in the alluvial plain between the rivers Río Manupare and Río Madidi, must be geologically young the regular circular shape, estimates of the age 11000-30000 years out.

Unlike other geologically young crater is the Iturralde Crater with only a few meters difference in height between the edge and the center is very flat, so that the crater - if there is an impact crater - may be sunk into the soft sediments and thus in the impact, no has border made of appreciable height.

Since the Iturralde Crater can be reached only with difficulty, he has hitherto visited only twice by scientific teams, most recently by a NASA team at the Goddard Space Flight Center in September 2002, both expeditions have no conclusive evidence for the formation of the Iturralde Crater can find.
