10,000 Lakes Archaeology proposes that the public archaeology program take place over one two-day weekend, with the possibility of limited public involvement for the two days immediately preceding the program. 10,000 Lakes Archaeology proposes that the public archaeology program consist of a geophysical survey, archaeological excavations, and mappmg. Geovhvsical Survey 10,000 Lakes Archaeology proposes that geophysical surveys be included in the public archaeology program. These surveys would be conducted by Archaeo-Physics, LLC. The goal of the Geophysical survey will be to locate and map subsurface archaeological features in support of a public archaeology program. Public participation in all aspects of the geophysical investigation will be encouraged, and the results of the survey will be presented to the public upon the conclusion of fieldwork. The geophysical investigation will cover a minimum of I acre and a maximum of 4 acres. The general procedure to perform the instigation will be to divide the survey area into a series of square or rectangular survey "grids." Each grid will be surveyed by taking readings at regular intervals along regularly spaced transect. Successive transects will be surveyed until the grid is completed. The value and position of each data point will be automatically recorded in digital format by the geophysical instruments. These data will then be used to construct a fmal composite digital image of the entire survey area. The geophysical control grid will be placed by Archaeo-Physics personnel prior to the investigation using an electronic total station. The investigation will utilize at least 2 of the following 3 survey methods; electrical resistance, ground penetrating radar (GPR), and/or magnetic field gradient. The two methods that are deemed most appropriate to the field conditions at the site (as determined after an initial site visit) will be selected. The results of the geophysical investigation will be presented to the public in the field, and also included in the final report. The geophysical section of the final report will explain the methods used during the investigation, present the results as high-resolution graphics, and provide detailed interpretations of the survey results. The geophysical survey will take up to four days, and will begin two days prior to the full-scale public archaeology program. Public participation during the preliminary two- day survey is encouraged, but the number of participants will need to be limited. (The public participation during the full-scale public program will not require such limitations.) The inclusion of the geophysical survey in the public archaeology program assumes the survey area is relatively free of trees, brush, and other obstacles. If the site contains trees, brush or other obstacles, the city will need to be clear the brush, in consultation with the archaeologists, prior to the geophysical fieldwork and public archaeology program. 10,000 14kes Arch4eology 2
