Clovis sites occur throughout the southwestern United States and northwestern Mexico, but are poorly documented in the central Rio Grande rift region. Here, we present data from two relatively unknown Clovis projectile point assemblages from this region: the first is from the Mockingbird Gap Clovis site and the second is from a survey of the surrounding region. Our goals are to reconstruct general features of the paleoecological adaptation of Clovis populations in the region using raw material sourcing and then to compare the point technology in the region to other Clovis assemblages in the Southwest and across the continent. Our results show that both assemblages were manufactured from similar suites of raw materials that come almost exclusively from the central Rio Grande rift region and the adjacent mountains of New Mexico. Additionally, we show that Clovis projectile points in the study region are significantly smaller than the continental average. Our results suggest that Clovis populations in this region operated within a large, well-known, and relatively high-elevation territory encompassing much of northern and western New Mexico.
The Plainview/Folsom-aged bison Bonebed 2 at Bonfire Shelter, originally excavated in the 1960s, is argued to be the earliest North American bison jump (Dibble 1970; Dibble and Lorrain 1968). Yet, it is far older than all other known jumps, and well south of where the great majority of these sites are found. Dibble (1970) reasonably argued that its age and location was not compelling evidence against it being a bison jump. However, Binford (1978) observed that the skeletal composition of Bonebed 2 did not resemble a kill. To assess whether Bonfire Shelter could have been utilized as a jump and whether it was, we explore two lines of evidence bearing on the issue, a GIS analysis of the site and upland topography, and zooarchaeological analysis of the recovered bison remains. Although our GIS analysis indicates that Bonfire Shelter meets many of the criteria of a jump locality, our reanalysis of the faunal remains suggests this was not the primary kill locus, but instead a processing area to which high-utility portions of at least 24 bison were transported and butchered. Where the bison were killed, and how, is not known.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
