“In the 90s, I did some petrographic microscopy for the UA Anthropology Department on Chaco Canyon pottery, comparing the contained sand grains to various source rocks, some of which were from the Chuskas.”
Very interesting (speaking as an old geologist and wannabe physical anthropologist)... Were the results of the study published?
I left town shortly thereafter to go work in a mine, and don’t know whether the results were published. I was (still am) a geologist; the microscopy job was just to make a little cash.
