GDG- Environmental history project

[Matthew and Tina Hauck]

Esteemed members,
   
            After a long break, I have decided to reignite a research project I started two or three years ago.  The project is an environmental history of the GNMP and the surrounding area.  Unfortunately, my notes are lost to the ravages of technology.  I have re-collected (or rather I ma in the process of re-collected as many of the sources as I can remember and I will post my working bibliography ASAP, but I was wondering if there is some obscure or odd source (or sources) that anyone knows of, that I might have left off.  
   
  Thank you for your time and assistance in advance.
   
  RYOS,
