Patterned Peat Lands

Dennis Cox has a new post at his blog, http://craterhunter.wordpress.com/2013/10/21/the-patterned-peat-lands/ …. he thinks he might have found some evidence of the Younger Dryas Boundary event in the Patterned Peat Lands of Minnesota. His next stop is Texas in his quest for craters and evidence of impact events.
