No. I do western US archaeology, and the range we usually need is handled well by radiocarbon dating. (Radiocarbon dating is expensive enough--I would hate to see what the various other forms of radiometric dating cost!)
I'll look through my notes for the AZ question.
I forgot to address the AZ question. Sorry, I don't know much about that area, but let me know what you are looking for and maybe I can point some useful directions.
Bummer about the uranium dating. (on my part, not yours) and I'm scared to ask you for a link concering the AZ dig. You still have yet to send me a two or three page MAX link, but I confess, you provide a heck of a lot of reading materials!
I'm out for now (as long as there are no more pings)
