Stone fire hearths and associated sub-surface cultural remains were the target of a Ground Penetrating Radar (GPR) survey at a pre-historic Native American archeological site near Dewey, Montana. GPR is a non-invasive geophysical survey technique. The GPR uses a transmitting antenna with a frequency of 1-1000 MHz to emit electromagnetic waves into the ground. The receiving antenna detects reflections caused by boundaries of contrasting electrical properties. As the distance of a survey progresses, ensuing measurements produce an image based on the returning reflections.
