Between July 7 and 10, a magnetic field-gradient survey was conducted at Site 48FR3123. Archeologists from the National Park Service, the Bureau of Land Management, and Wyoming State Archaeologist Office participated in the magnetic field-gradient survey. The magnetic field-gradient survey with a Geoscan Research FM36 fluxgate gradiometer was performed at the 0.1 nT level of sensitivity in order to detect the potential of buried hearth and fire pit features on the site. A total area of 10,800 square meters was investigated during the magnetic field-gradient survey. The survey utilized the magnetic field-gradient survey methodology employed by Dr. Lewis Somers (1994) in his investigations of archeological sites located in a sand dune setting in southwestern Wyoming. As a result of the application of Somers' methodology, 52 potential locations at the 99% confidence level were identified in the magnetic data set. Archeological excavations are needed to investigate the 52 magnetic anomalies in the magnetic survey data.
