I've not been active in geology in some time; I pursued a Ph.D. in Environmental Science for awhile, looking at groundwater pollution from the lead-zinc mine dumps at the extreme NE corner of Oklahoma near the community of Picher - but I was getting too ill to finish mt work, and woked as a librarian at the college level until I was too ill to do even that. In 1992 I took Social Security Disability. I have poked around a little bit around Gadsden, looking at mineral deposits. If you want to e-mail directly, my e-mail address is
