Description:
The "Springerville area," Apache County, Arizona (Fig.l) initially
was selected as a site-specific target for geothermal exploration on the
basis of (1) moderate to high chemical geothermometers, (2) the proximity
of young volcanics, and (3) the intersection of regional lineaments
that were defined by the alignment of young volcanics in the White Mountain
volcanic field (Hahman, pers. commun., 1977). Based on prior work by Swanberg and others (1977), the initial program focused on the area between the towns of Springerville and St. Johns. Later work directed exploration farther south between the towns of Springerville and Alpine, and to the west thereof.
Sufficient data were generated to indicate a potential geothermal resource and
thus to encourage the Bureau of Reclamation to fund specific geophysical surveys (passive seismic, d.c. resistivity, telluric current, and
heat-flow drilling) that supplemented investigations being funded by the
Department of Energy, Division of Geothermal Energy.
