It will be recalled that Coon Butte is a low eminence, with a shallow depression in the summit about half a mile across that has become widely known on account of the supposition that this crater-like basin was formed by a huge meteor striking the earth at this point and throwing up the low wall all around. Contrary to the recently expressed views regarding the origin of this remarkable crater the most critical evidences seem to indicate that this feature of the local landscape is only one of the many manifestations of the explosive type of vulcanism so prevalent throughout this region.
