35 The Wyoming Archaeologist Volume 51(1), Spring 2007 The Hogsback site (48UT2516), located in Uinta County, Wyoming, was discovered dur- ing construction of the Kern River Expansion pipeline and subsequently excavated by Alpine Archaeological Consultants, Inc. The site’s cultural remains, including one Early Archaic housepit, 31 slab-lined and earthen-lined ther- mal features, laked and ground stone tools, worked bone, and a distinctive drilled stone ob- ject, range in age from approximately 5280 B.P. to 1010 B.P. and suggest use of the site was re- current and occurred as part of annual resource procurement rounds. Floral and faunal remains suggest site inhabitants consistently made use of nearby pronghorn and biscuitroot resources throughout multiple periods of site occupation. However, loral evidence also suggests site occupants during earlier occupations supple- mented these resources with additional foods. Altogether, cultural remains at the Hogsback site indicate levels of hunter-gatherer group mobility may have been at their lowest during the Early Archaic period and resource procure- ment practices may have become increasingly based on achieving higher levels of group mo- bility over time, as was occurring regionally within the Wyoming Basin during the Archaic and early Formative periods. The Hogsback site HUNTER-GATHERER MOBILITY FROM THE EARLY ARCHAIC TO THE LATE PREHISTORIC PERIOD: INVESTIGATIONS AT THE HOGSBACK SITE (48UT2516), A HOUSEPIT SITE IN SOUTHWESTERN WYOMING by Summer Moore provides a long-term data set against which to evaluate local changes in resource procurement and settlement practices over time. This paper makes use of an in-depth analy- sis of cultural remains at the Hogsback site (48UT2516), an Archaic housepit site in south- western Wyoming (see Figure 1), to explore a set of issues relating to hunter-gatherer mobility in the Archaic era. This site, which was reoc- cupied successively and almost continuously over a period of at least 4,000 years, provides an ample data set against which to discuss such topics as changing settlement patterns and subsistence strategies. In this paper, it is argued although cultural use of the Hogsback site re- mained essentially constant over time in terms of the types of resources chosen for exploitation, certain changes in site use through time are ap- parent, in terms of occupation duration and the relative signiicance of each occupation within annual resource procurement rounds. These arguments are based on structure and feature morphology, as well as artifactual evidence. HISTORY OF SITE INVESTIGATIONS The Hogsback site was discovered during an open-trench inspection of the Kern River 2003 Expansion Project pipeline trench, in which
