Since the early 1970s, Great Basin archaeologists have debated projectile point chronology, most specifically focusing on the duration of certain types in different parts of the Basin. Large corner-notched types play a central role in this debate, since in some areas they appear during the Early Holocene and persist until recent times, while in other areas they represent much shorter time spans. Further, the occurrence of large side-notched types is limited primarily to those areas in which the large corner-notched types have long temporal distributions. This paper examines the component attributes of large side-notched and corner-notched point types and offers a functional explanation for their differential distribution in time and space.

The inadequacy of typological approaches has led to our attempts to improve temporal resolution by means of obsidian hydration dating. Increasingly, archaeologists working in the Great Basin have adopted obsidian hydration dating as an adjunct to standard dating techniques, some regarding surface artifact dating as an acceptable extension of the approach (e.g., McGonagle 1979; Bettinger 1980, 1989; Jackson 1984a; Tuohy 1984; Zeier and Elston 1984). While we have reservations about the use of obsidian hydration dating for precise chronometric assessments of surface artifacts (cf. Leach 1988; Bettinger 1989), the technique appears to have merit as a relative dating tool (Michels 1967, 1973; Michels and Tsong 1980; Jackson 1984a). In this paper we report on a study of 115 obsidian artifacts recovered from seven archaeological sites of late Pleistocene-early Holocene age. We begin with general background of the dating method and of our Butte Valley studies, and then turn to the results of our obsidian source and hydration analyses. We conclude with an evaluation of obsidian hydration for delimiting chronological information for the surface archaeological record.

This paper presents a synopsis of our field studies along with results of technological, lithic source, and obsidian hydration analyses applied to the site and offsite assemblages.

In sum, where should Great Basin archaeology be moving in the 1990s? That question is largely answered by the research now underway. Significant substantive and technical advances will certainly result. How these will play, framed as they are by processualism in a discipline recasting its theoretical structure is uncertain. In any case, the 1990s should prove to be a most discomforting but exciting episode.

This paper reports the authors' assessment of these issues and considers the occupational record of the Sunshine Locality in light of the environmental and cultural history of the region.
