That's her. The link you provided look familiar. I think that is the first article I read about it which got me thinking. Now tha I have the names, I can go look for their published data. Do you haveany clues as to what method they might have used in the 70's? do you know what college or institution that Williams worked out of? USGS?

Thanks for your help, as usual.

For the college, my recollection was it was Eastern New Mexico University, Portales.

Also, try googling "Cynthia Irwin-Williams" in addition to Cynthia Williams.
