AbstractStudent members of the Arizona State University Walnut Creek Archaeological Field Camp excavated six pit houses and located several more at Walnut Creek Village, located 10 mi. southeast of Young, Arizona, during the summer of 1967. Three of the pit houses were Hohokam and three were Anasazi; one of the latter was a subcircular kiva with sipapu-resonator complex of distinctive western Pueblo style. The occurrence, during the ninth century, of these two archaeological groups, side-by-side, in an ecological setting which is unusual for the Hohokam contributes to our knowledge of them and permits inferences concerning the Hohokam community at Roosevelt:9:6, 30 mi. away. Additionally, hypotheses concerning Hohokam ceremonial and communal houses at other sites can be evaluated.

A long-term approach is definitive for my career, which has evolved at a single place over more than 30 years. But the Long-Term Research Ecology (LTER) program, and especially its urban research, has broadened my thinking far beyond the boundaries of the ecosystem science tradition in which I was trained. I have added to my expectations of students that they learn collaboration, use a diversity of approaches, explore existing data, and document and archive their own data. I anticipate that they will find careers in a broader diversity of areas than academia. The urban research in the LTER program has provided an incentive for me to work on communicating with the public, educators, students, and practitioners. I am still learning but am much more motivated than previously to reach out to these communities. Collaboration is standard practice for ecosystem science but the LTER program has expanded the types of scientists with whom I collaborate as well as the extent of my external collaborations. My decision to lead the Central Arizona–Phoenix (CAP) LTER project was therefore life-changing in extending the horizons of my science, mentoring, collaborations, and outreach. Since 1997, when the CAP program began, I have been involved in the LTER program. I was the original principal investigator, and Charles Redman and I were codirectors from 1997 to 2010. In 2010, after successfully renewing the CAP project, I took a 2-year hiatus to work at the National Science Foundation (NSF). I returned in 2012 and am currently the principal investigator and sole director. This has been my only involvement in the LTER program throughout my career, although as an undergraduate, I conducted research at what was to become the H. J. Andrews Experimental Forest site. I am trained as a stream ecologist and biogeochemist, and I have been at Arizona State University (ASU) for my entire graduate and postgraduate career. Currently I am a professor, having moved through ranks, first as a non–tenure track research faculty member, then as an “academic professional,” and finally as an associate and then full professor. I lead somewhat of a double life, scientifically.

AbstractTest excavations made in the spring of 1964 along the Salt River near Mesa, Arizona, by personnel from the Department of Anthropology, Arizona State University, provide new data on the earliest Hohokam. The Red Mountain site produced inhumations, a burial cairn, a different grinding-tool complex, and other items previously unknown in early Hohokam associations. Since only Vahki Plain and Vahki Red pottery are present, the site might be designated Vahki phase; however, this designation alone would obscure and ignore the important differences that are present. There are several better interpretations, two about equally plausible: (1) since the only other excavations in early Hohokam sites in the Red Mountain area have also produced inhumations and at least one other burial cairn, and these sites span the Pioneer period, one can emphasize the persistence of differences in the Red Mountain area by identifying a "Red Mountain branch" Hohokam at least through the Pioneer period; hence, Vahki phase, Red Mountain branch. This designation employs a traditional South-western concept. On the other hand (2) if one subscribes to the hypothesis that both Mogollon and Hohokam are derived from the San Pedro stage Cochise, the Red Mountain data support the identification of a phase transitional between San Pedro stage and Vahki phase — Red Mountain phase. This latter interpretation does not preclude a Red Mountain branch.

Low Energy Electrons

A new field emission scanning transmission electron microscope has been constructed for the NSF HREM facility at Arizona State University. The microscope is to be used for studies of surfaces, and incorporates several surface-related features, including provision for analysis of secondary and Auger electrons; these electrons are collected through the objective lens from either side of the sample, using the parallelizing action of the magnetic field. This collimates all the low energy electrons, which spiral in the high magnetic field. Given an initial field Bi∼1T, and a final (parallelizing) field Bf∼0.01T, all electrons emerge into a cone of semi-angle θf≤6°. The main practical problem in the way of using this well collimated beam of low energy (0-2keV) electrons is that it is travelling along the path of the (100keV) probing electron beam. To collect and analyze them, they must be deflected off the beam path with minimal effect on the probe position.

The standard ASUDAS scoring system (Arizona State University Dental Anthropology System) is used to assess dental morphological variations in modern humans. It is also frequently used to study, score, and compare morphological variations in fossil hominin taxa and to examine their phylogenetic relationships. However, using ASUDAS in studies of this type is under debate because it is based on modern Homo sapiens populations and does not appear to cover all variations observed in fossil Plio-Pleistocene homi- nins. Our observations and coding of 178 dentals casts of Plio-Pleistocene specimens based on ASUDAS and from the literature have confirmed the need to adapt the standard system to fossil hominins. In this initial study, we propose that the scoring procedures for some morphological characters need to be readjusted, while others could be standardized following the ASUDAS system.
