The data recovery of seven early Holocene archeological sites in Nelson Wash, National Training Center, Fort Irwin, California was conducted during the summer of 1983. This report contains the description of artifacts recovered from these sites followed by an analysis of use wear, assemblage composition, chronology, subsistence, and settlement patterns directed toward understanding early Holocene cultural adaptation in the Mojave Desert. A typological key for identifying Lake Mojave and Pinto points is proposed and evidence presented of a Lake MojavePinto cultural continuum. (Figure 1-1). The project area includes former Range 14/Nelson Wash in the Nelson Lake drainage basin, 11-13 km north of the NTC cantonment area.
PROJECT HISTORYArcheological inventory of Nelson Wash was undertaken in January, February and March, 1982 prior to the 1982 Gallant Eagle training exercises. As a result of the initial survey, eleven prehistoric archeological sites were discovered and recorded in Area 6G including seven sites in the Range 14/Nelson Wash area (Robarchek et al. 1984, 99-115 in unavoidable impacts to the six sites within the range project boundaries; therefore, further evaluation of the sites to obtain sufficient information to guide data recovery was planned.With the exception of 4-SBr-4966, however, testing and documentation of the Nelson Wash sites was deferred, as there was a possibility that buried live ordnance was present in the project area.Evaluation of 4-SBr--4966 was restricted at this time to the collection of tools and debitage from the surface and the excavation of four lxl m test units to assess the extent, integrity and maximum depth of the site deposits (Skinner etal. 1984, 203-224).Due to the urgency of the NTC range construction program, data recovery of the six NelsonWash sites was undertaken from July to October, 1983 immediately following the completion of the 4-SBr-4966 evaluation, the completion of a research design and the clearance of unexploded ordnance from the Nelson Wash area by NTC personnel. Results of the field phase of the data recovery project were reported by Vaughan (1984). As the first phase of data recovery, heavy equipment was used to explore known or anticipated subsurface deposits at 4-SBr-4966, 4-SBr-4963 and 4SBr-4965. Subsequent data recovery efforts at these sites were based upon the results of the first phase. Data recovery at sites 4-SBr-4967, 4-SBr-4968 and 4-SBr-4969 was restricted to surface samples. In the course of the Nelson Wash data recovery fieldwork phase, a new site, 4-SBr-5267, was discovered north of 4-SBr-4966 (Vaughan 1984:61-64). As the site was not included in either the original budget and schedule or research design, work at the site was limited to surface collection of a small sample of tools and debitage from ten clusters, or loci, of tool concentrations (Vaughan 1984:62).In addition to the discovery of 4-SBr-5267, the 1983 fieldwork determined that cultural materials extended far beyond the mapped boundaries of 4-SBr-4969 (Robarchek e...
