I found the following article from the August 3, 1962 Time Magazine: Science: Conquistadors' Capital. It is about the excavation work that was done on the first Spanish capital of New Mexico: San Gabriel de Yunque. It's an interesting read.
You can find out more about the dig in the Winter 2008 Issue of the UNM Anthropology Newsletter (page 8). The article aludes to a Time Magazine article that Tony Hillerman wrote about the dig. I wonder if it's the article above?
