Gravity observations were made at 130 new locations near McDermitt, Nevada during September 14 to September 20, 1976 (fig. 1). The field-work was done by Donald Plouff and Arthur Conradi, Jr., using LaCoste-Romberg gravity meter G-192. The purpose of the 1976 survey was to supplement previously reported gravity data in this area (Plouff, 1976) and to tie the datum of the present and previously established gravity stations to the datum of the International Gravity Standardization Net 1971 (IGSN 71) described by Morelli (1974).
