of the volcanic hill in the center.
The 2010 UNM Southwestern Field School will be held from June 1-July 9. One of the oldest field school programs in the Southwest, it offers students the opportunity to learn basic field and laboratory skills within the context of a particular research problem. This summer, the field school will be held at Deann’s Site (LA 134644), a small Folsom bison kill and short-term campsite located on the Llano de Albuquerque (“West Mesa”) west of the Albuquerque Volcanoes. This site was discovered in 2001, tested between 2002 and 2004, and was the scene of the 2006 Southwestern Field School. The work accomplished thus far has shown it to contain flaked stone artifacts and poorly preserved bison remains in a shallow wind-blown sand deposit adjacent to a small playa (dry lake) basin.
Research at Deann’s Site is an important component of a long-term project investigating Folsom land use and paleoecology in the Middle Rio Grande Valley of New Mexico. As participants in the field school, students will learn:
While the main focus will be excavation at Deann’s Site and the playa adjacent to it, students will also learn archaeological survey techniques on parcels of land on the Llano de Albuquerque west of Deann’s Site. Day-long trips will be made to important sites such as Blackwater Draw in east-central New Mexico and a chert source in the northeastern Zuni Mountains.

Folsom
The Folsom cultural complex derives its name from the small town of Folsom in northeastern New Mexico, where the distinctively grooved or fluted Folsom points were first discovered in association with the remains of more than 30 bison in 1926. The bison are a late Pleistocene-early Holocene species known as Bison antiquus, which is related to today’s bison (Bison bison) but approximately 15-20 percent larger. Excavation of the Folsom site was of critical importance to North American archaeology, inasmuch as it was the first site to demonstrate that humans were contemporary with extinct animal species, thereby implying an age of at least 10,000 years before present. Renewed investigation of the Folsom site in the late 1990s produced radiocarbon dates of approximately 10,500 years before present. In the past 80 years, numerous other Folsom sites and artifacts have been found and investigated from southern Canada south into Chihuahua, and from the Rocky Mountains east to Iowa. Radiocarbon dating conducted at several sites suggests that Folsom dates to between 10,200 and 10,900 radiocarbon years before present. In addition to points, Folsom sites typically produce retouched flake tools for butchering, hide processing, and wood working, as well as waste flakes from tool manufacture. At sites where preservation is good, bone tools and ornaments may be recovered.
Bison seem to have been central to Folsom subsistence; if any faunal remains are preserved at Folsom sites, bison is almost always present and usually most abundant. Other species have been found in small numbers at Folsom sites as well, including antelope, cottontail and jackrabbits, wolf, coyote, as well as rodents. Folsom lifeways seem to have been organized around the hunting of bison, which often seems to have entailed a fully nomadic existence following bison herds. Evidence of such high mobility is seen in the presence of flaked stone tools made of lithic materials several tens to a few hundred kilometers distant from bison kill sites or campsites, and by the relative paucity of artifacts left at such sites.

Folsom sites were discovered in central New Mexico in the 1940s and 1950s; the University of New Mexico has a long tradition of Paleoindian research in the Middle Rio Grande Valley. Within the area from Bernalillo on the north to the Rio Grande-Rio Puerco confluence on the south, there exists a surprisingly rich record of occupation by these ancient hunters. Previous research by UNM graduate students and faculty within this region began with W. James Judge’s survey in the late1960s through early 1970s. His work, done in collaboration with a small number of amateur archaeologists and fellow graduate students, resulted in the identification of nearly 60 Paleoindian sites (Judge 1973). Half of them were Folsom sites. He was the first to demonstrate the strong relationship between playas (dry lake beds) and Paleoindian sites (Judge and Dawson 1972). He recorded Deann’s site in 1971, although his work there was limited to surface collection of a few artifacts.
In the late 1960s, Jerry Dawson, another UNM graduate student, conducted excavations at the Rio Rancho Folsom site, which, until 2000, was the only Paleoindian site in the Middle Rio Grande Valley to have been excavated (Dawson and Judge 1969). Renewed work at this important site took place in 1999 and 2000 (Huckell and Kilby 2002).
In the 1990s, UNM graduate students Daniel Amick and Philippe LeTourneau utilized data from museum and amateur collections to investigate Folsom land use in the southern Plains and Southwest, including the Middle Rio Grande Valley (Amick 1994,1996; LeTourneau 2000). Using artifact assemblage composition and lithic raw material sourcing, they were able to initiate study of how the Middle Rio Grande region fit within much larger-scale patterns of Folsom land use.
In 2001 and 2002, the UNM Southwestern Archaeological Field School conducted excavations at the Boca Negra Wash Folsom site, located on the east side of the Albuquerque Volcanoes. This site consists of two spatially separate camp localities occupied for very short periods after one or more successful bison kills around the margin of a small playa. Shallowly buried in eolian deposits, Boca Negra produced a few thousand artifacts and small fragments of bison tooth enamel and bone. The lithic raw materials present at the site suggest that the occupants of the site obtained stone for tool-making from at least three sources in northwestern New Mexico. Loading up with pink chalcedony from the Chuska Mountains on the Arizona-New Mexico border, they next moved east to the Zuni Mountains where they acquired a yellow chert with black spots. They then traveled northeastward into the Jemez Mountains to obtain Pedernal chert and Valle Grande obsidian before reaching the Middle Rio Grande Valley (Huckell and Kilby 2000; Huckell et al. 2002, 2003).
Research at Deann’s site in the summer of 2006 help broaden understanding of Folsom land use in the Middle Rio Grande Valley, and showed a very different pattern of lithic material use and movement than that seen at Boca Negra Wash. Preliminary indications are that its occupants did obtain pink chalcedony from the Chuskas, and then moved east to the Zuni Mountains where they procured the black-spotted yellow chert and a distinctive opaque white chert. However, they avoided the Jemez Mountains and instead continued due east from the Zunis, loading up on chert and chalcedony from cobble sources along the western margin of the Llano de Albuquerque. This suggests the existence of flexibility in the pattern of Folsom group movements across northwestern New Mexico.
Playas

Overview of Deann's Site with playa in the background
(note backhoe trench backdirt)
Away from the river, the Middle Rio Grande Valley is largely a landscape of grasses, shrubs, and occasional junipers; this is particularly true for the plains area of Llano de Albuquerque. In an arid environment dominated by wind-blown sand deposits, small closed basins that hold water for a few days or a few months can be of critical importance. These basins are known as playas, a Spanish word referring to dry lake beds that also means “beach.” Not only do playas offer sources of water and nutritious plants for grazing animals such as bison, but may be attractive to humans as well. This certainly seems to have been the case for Paleoindians, who focused a considerable portion of their energies on hunting bison. In turn, playas are important to archaeologists today, not just because of the sites that may be nearby but because the deposits contained within these playa basins can hold records of past climatic conditions and plant communities
As part of investigations at the Boca Negra Wash Folsom site in 2001-2004, both coring and backhoe trenching were used to reveal a stratigraphic record of the playa at that site. Nearly 2 m thick near the center of the playa, the deposits span most of the last 14,000 years (Holliday et al. 2006). The playa at Deann’s site was also studied, and will be investigated further this summer using coring; students will learn how to recognize and describe the deposits it contains.
