Logan Simpson Design environmental consultants are currently conducting a number of long-term, research-driven inventory projects for the Bureau of Land Management in Lincoln County, Nevada.
As part of a sample archaeological inventory near Delamar Lake, LSD has developed a GIS predictive model to help identify high, medium, and low probability areas of cultural resources associated with the Terminal Pleistocene-Early Holocene (TPEH) transition period.
Our GIS model focuses on several critical factors likely to influence site distribution during the TPEH transition period such asproximity to high-probability landforms (lakeshores, beaches, or indented shorelines); extinct marshes or deltas; and elevated surfaces near wetlands.
Delamar Lake is situated within a Pleistocene pluvial lake bed and, like other nearby pluvial lake beds, is a high probability area for Paleoarchaic archaeological sites. The now arid lake would likely have supported a marsh/riparian-type ecosystem during the TPEH.
Throughout the process, our goal was to identify the TPEH, or Paleoarchaic, archaeological sites near Delamar Lake in order to establish baseline inventory data for locating TPEH-aged cultural resources in other pluvial lakebeds in Lincoln County.
