Prehistory

Pahranagat Valley Landscape ca. 1250-1700 A.D. site rendition by S. Stearns

Early Paleo Indian groups probably first entered in Nevada during the late Pleistocene where is an indirect association of Clovis projectile points.  Dating these sites in Nevada and elsewhere in the Great Basin remains elusive but across North America, dozens of Clovis sites appear contemporaneous with the abrupt onset of Younger Dryas (YD) cooling (12.9 Ka.).  New evidence from excavation projects at Paisley Caves in Oregon and Bonneville Estates in northeast Nevada may indicate that another cultural group entered Nevada during the same period of the Clovis groups.  They are represented by the Great Basin Stemmed tradition and archaeologists are currently debating the data based on excavations of Paisley caves.

Prehistoric paradigms have been developed regionally in Nevada for the east slope of the Sierras, in the Carson and Humboldt Sinks, Central, Northeastern and Southern Nevada.  These are framed within the Archaic Period (extending over 10,000 years) until Euroamerican period.  In general they reflect climatic adaptation, settlement subsistence changes and group migrations and they are associated with technologies that are identified in their projectile point styles, ceramics (in some areas) and architecture.
