Permian Purgatory Puddingstone


I’ve lost track of the number of public presentations I’ve given to community groups.  I’m sure it’s more than five hundred.  Most involve three basic themes:

  • Signature landforms such as abandoned stone walls and kettle lakes, which are icons to regional cultures, 
  • Environmental citizenship,  during which I explain my positions on public policy issues ranging from nuclear waste disposal to escaped emus.
  • Cultural geology, emphasizing the science writings of Henry David Thoreau. 
  • Landscape Art, my interpretations as part of cultural geology, given at the Wadsworth Athaeneum in Hartford, CT, the Florence Griswold Museum in Old Lyme, CT, and the Newport Art Museum, in Newport RI.

These talks, which average about seven hours each (travel, setup, presentation, Q&A, takedown, return travel), are given as my schedule and commitments allow, usually for a break-even honorarium. 

Photo:  Permian Purgatory Puddingstone.  The name alone invites a speech. I’ts a squash-pebble conglomerate in Narragansett Bay, RI formed by late Paleozoic mountain streams when New England had Himilayan proportions.  

Partial List of Programs

I’ve always given talks to community organizations.  I didn’t keep track of them until the Stone Wall Initiative went on line in the Fall 2004. For the next three years I kept track until I gave up, once again.  Below I list a few years  to give you a sense of the concentration and breadth of interest.
