The development of FGV studies in Nevada are associated with a variety of different factors - our longstanding Lake Tahoe region FGV investigations, several thesis projects from the University of Nevada (Reno), a couple of power transmission line projects in east-central Nevada, and some spillover from source studies at the Utah Test and Training Range in western Utah. The delineation of the different geochemical sources and the extent of their geographic availability are definitely topics that are currently in flux, particularly in the east-central part of the state. Trace element analyses of a large number of FGV artifacts from northern Nevada indicate that Steamboat Hills, Coyote Spring, and Smith Valley were the most intensively-utilized of the bunch during the prehistoric period.
