An Application of Ground-Penetrating Radar at a Greater Yellowstone Area Ice Patch
Ice patches are an irreplaceable archive of past events. With atypical melting now occurring around the world, it is important to be able to quantify and interpret the potential of what remains in areas of archaeological interest. A ground-penetrating radar (GPR) survey was conducted at an archaeolo...
