Bits about me, mostly oldEdit

Joined the Wikipedia project in June 2006. Time flies....

I review books for many print and online publications. I'm a retired mineral exploration geologist, formerly based in Arizona and New Mexico, now living on the Central Coast of California. Served in the USNR, sometime after Adm. Farragut. Older than dirt.

Other interests/(semi?)-expertise:

  • Science fiction
  • SW US history and prehistory
  • Northern Mexico history and prehistory
  • Ethnographic art
  • Paleoclimates in the geologic record, and implications for modern climate change
