Natural Cement lecture on Friday

I'm giving a talk on the "“Geology and the Rosendale Natural Cement Industry” Friday evening, starting at 7:30 pm, at the Mid-Hudson Gem & Mineral Society meeting in Poughkeepsie.   It's free and open to the general public.  The location is at the Mill Street Loft, 46 Pershing Avenue, Poughkeepsie.

This local industry once produced more than half of the natural cement used in the United States!  Come and learn how ancient subtropical seas and massive Himalayan-scale mountains once existed here in New York and helped form this once-important economic resource that still has an effect on our local ecosystem.
