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,…

Any comprehensive interpretation of GPR data must include the integration and analysis of both amplitude slice-maps and two-dimensional reflection profiles. Often one method can yield results that the other cannot, producing important insights. One example from Ireland shows how slice-maps produced very useful images of subtle post molds, which outlined a crannog in a pond…

Geophysical investigations were conducted at three Carrizo Corridor Stage Stations within the Anza Borrego Desert State Park to search for buried objects and structures associated with historic occupation of these sites. Field surveys were conducted on March 21-23, 2001 at Carrizo Creek, Palm Spring, and San Felipe Stage Station. Three geophysical techniques were employed: ground…

Aboriginal people in Cape York Peninsula area of Australia have strong emotional attachment to cemeteries and the burial places of their ancestors. Often, as at Mapoon, in northern Queensland, many such places are unmarked and neglected. The graves can be difficult to identify on the ground surface, either because they were never marked, or because…

Geophysical investigations were conducted at the La Purisima Mission State Historic Park to understand potential impacts due to the proposed development of a new visitor’s center. The portion of La Purisima State Park studied is located near the park entrance, just north of the intersection of Purisima Road and Mission Gate Road, in Lompoc, California.…

A GPR program was conducted on a hilltop on the island of Brač, Croatia to assess whether this area was a fort, or a defensive structure, as had been suggested by people for many years. Its location, the sight-lines from the ridgetop, and the surface artifacts all supported this idea perhaps dating from the Bronze…
