“…Specifically, we use a geographic information system (GIS)-based Euclidean distance calculation with digital reconstructions of pluvial lakes and paleoshorelines, site locations, and artifact distributions, to evaluate the proposed association of crescents with wetland habitats in Western North America during the terminal Pleistocene and early Holocene (TP/EH). During this time, wetlands were the focus of subsistence and settlement patterns in the Great Basin and interior California (Beck and Jones, 1997; Beck et al., 2002; Elston and Zeanah, 2002; Jones et al., 2003), as well as the California Coast (Erlandson et al., 2008b, 2011; Lightfoot, 1993; Moratto, 1984) where high-ranked food sources were especially abundant (Jones et al., 2003:7). The goals of our analysis are to contribute to a deeper understanding of crescents, their distribution, and the environmental conditions under which they were produced, used, discarded, and recycled.…”
