A Test of Geophysical Prospecting for the Detection of Prehistoric Canals on the Gila River Reservation, Arizona
This report documents a project to apply geophysical prospecting techniques at known locations of prehistoric canals in the Gila River Reservation. The project goal was to test the ability of several geophysical prospecting techniques to image buried canals in the Gila River floodplain. Four geophysical prospecting approaches were tested: ground penetrating radar, seismic reflection imaging,…

Interesting that apparently dry salt had such a devastating impact on the ability to use electromagnetic radar. I don’t think of free salt having much electron mobility. Darn.
…something to consider in the future. Thanks!

Nice work. It is a shame that the GPR profiles of the channels were not good because of the salt in the soil.
