Results and interpretation of exploratory drilling near the Picacho Fault, south-central Arizona
Thomas L. Holzer
1978, Open-File Report 78-1016
Modern surface faulting along the Picacho fault, east of Picacho, Arizona, has been attributed to ground-water withdrawal. In September 1977, three exploratory test holes were drilled 5 km east of Picacho and across the Picacho fault to investigate subsurface conditions and the mechanism of the faulting. The holes were logged...
