several Chacoan burials. Frances Joan Mathien of the National Park Service's
Chaco Research Center at UNM helped us find important reference material and
answered questions about the ancient turquoise trade. Garland Bills, chair of the
Department of Linguistics at UNM, answered our questions about Puebloan
languages. Annotated illustrations were cheerfully and efficiently provided by
Joyce Raab with assistance from Heidi Reed and Angela Rogers of the Chaco
Archive, a remarkably valuable facility housed at UNM's Zimmerman Library.
The superb maps were created by Carol Cooperrider of Albuquerque, and copy-
editor Jane Kepp in Santa Fe added much to the quality of the finished text.
Thomas Mortenson provided the figures for chapter 9. Cliff and Nancy Mills of
Santa Fe graciously provided the arresting cover and title page views of Taos
Pueblo from their important collection of Territorial New Mexico photographs
(taken by Cliff's great-grandfather, B.G. Randall). On sunny days their display
table can be found on Santa Fe's charming plaza.

Finally, I am enormously grateful to Linda S. Cordell, who formally reviewed
this volume for UNM Press. She suggested remedies for many errors of fact,
tone, and interpretation. Nonetheless, I plotted my own intellectual course on
a number of points. Since I consider Cordell to be one of the "best in the busi-
ness," I have done this at some peril to my reputation, rather than to hers. She
warned particularly that I not use definite dates for a number of events (such as
the drought of A.D. 1090), because new research might change them by a few
years one way or the other. This warning I pass along to the reader--archaeol-
ogy is a dynamic field, and what we know or think we know today will change.
