The Bureau of Land Management (BLM), responding to applications made by residents of the Pahranagat Valley, plans to sell parcels of land on which Unintentional Trespass Acts (UTA) have occurred. These UTA lands have been used during the last 100 or more years for various agricultural purposes including irrigation, agriculture and livestock operations. Cultural material was recorded on these parcels by Brian Hattoff, then archaeologist for the Las Vegas District, BLM. Mitigation of the adverse effects that might occur to cultural resources as a result of the land transfer from federal to private ownership was recommended. In response to a request made by the current BLM Las Vegas District archaeologist, Stanton Rolf, the Archaeological Research Center (ARC} of the Museum of Natural History, University of Nevada, Las Vegas (UNLV) submitted a mitigation proposal that recommended the collection of cultural material from 25 percent of the surface area of the UTA land sales.
