A recent article by Kenkmann et al. in the GSA Bulletin titled
Secondary cratering on Earth: The Wyoming impact crater field
has led to a plethora of noticeable reactions especially on the internet and has led to an extensive critical commentary article that can be clicked HERE on the website for an introduction and HERE as a PDF. The commentary article, which comprehensively contrasts the Wyoming impact crater field with the Chiemgau impact crater field, accuses the authors of serious methodological errors and scientifically incorrect work. The conclusion is that this alleged Wyoming secondary crater field does not exist.
