a The structure appears to be created in the glacial remains of the Late Wisconsin North American glacial episode, 25,000–12,000 years ago.
Some time ago the Plevna/Tomvale structure was suggested to me, from an unknown source, as a possible impact crater. I was asked to explore it for documentation.
Drilling the site may be the only possible means of identification.
