Field report of geophysical investigations at the proposed La Purisima Mission Visitor Center
Abstract
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. Field surveys using four geophysical techniques were conducted on September 23-25, 1999 and October 27-29, 2000 to search for buried objects and structures associated with historic occupation of the site. Four geophysical techniques were employed at La Purisima: ground penetrating radar (GPR), electromagnetic conductivity (EM), total magnetic field measurement (MAG), and seismic reflection imaging (SRI).
