Field Report for Magnetic Field-Gradient Survey of Site 48FR3123, Fremont County,Wyoming

摘要

Between July 7 and 10, a magnetic field-gradient survey was conducted at Site48FR3123. 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 utilize the magnetic field-gradient survey methodology employed by Dr. Lewis Somers in his investigation 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.
