Consensus opinion does hold a cosmic impact accountable for an enigmatic Mid-Pleistocene event - the Australasian tektite strewn field - despite the failure of a 60-year search to locate the causal astroblem. For the past 30 years, scientist have been searching for the requisite astrobleme within the strewnfield. Such a location violates the findings from the other three known impact site and correlated strewn fields. In those three situations, the strewnfield has been found along a narrow arc offset asymmetrically away from the impact site, and showing a large geographic displacement away from the impact site.
