An overview of the geothermal potential of the Springerville Area, Arizona

The "Springerville area," Apache County, Arizona (Fig. 1) initially was selected (Hahman, personal commun., 1977) 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 based on the alignment of young volcanics, in the White Mountain volcanic field. 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 serious attention as far south as the town of Alpine. The land status of the study area can be seen in Figure 2. North of Springerville land ownership is a checkerboard of private, state, and federal land, the latter managed by the Bureau of Land Management (BLM). The southeastern area is Apache National Forest. To the southwest are lands of the Sitgreaves and Apache National Forests and the White Mountain Apache Indian Reservation. (25 pages.)
