During this period, reconnaissance investigations of more than 100 thermal spring sites and fumarole fields located in Alaska were conducted by DGGS. Purpose: Only a few geothermal areas in Alaska have thus far received any detailed investigation and, except for reconnaissance studies, most of the state's geothermal resources remain virtually unexplored. There has been a growing awareness, however, that geothermal resources can play a significant role in meeting the states energy needs, particularly in rural areas. The primary purpose of this map, therefore, is to aid potential users in development of geothermal resources in a manner beneficial for Alaska.

Digital thermal well and spring data available from GEOTHERM Project, U.S. Geological Survey, 345 Middlefield Road, MS84, Menlo Park, California 94025. Native_Data_Set_Environment: Microsoft Windows XP SP2, ArcGIS 9.+, and any text editor. Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Precisions are listed in Table 1 of Motyka et al., 1980 quoted from Skougstad and other, (eds.) 1979. Logical_Consistency_Report: Polygon topology is present on appropriate coverages; others are line or point coverages. Completeness_Report: This dataset includes coverages that contain information about volcanic vents, geothermal gradient test holes, hotsprings, potential exploration areas for geothermal resources, and Quaternary or Quaternary-Tertiary volcanic rocks. This work includes reconnaissance of site geology and hydrology, investigation of thermal spring and fumarole characteristics including temperatures and flow rates, and geochemical sampling of thermal fluids. This map is based largely on information gathered from these reconnaissance studies plus additional information obtained from more detailed studies recently conducted at several of the more promising geothermal areas. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Location data were determined visually using topographic maps at a scale of 1:63,360 and 1:50,000 (nominal) scale, and color-infrared aerial photographs. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 100 Horizontal_Positional_Accuracy_Explanation: Total potential horizontal error for surficial-geologic map features is estimated to be approximately 100 meters. Surficial-geologic map data have a horizontal positional accuracy dependent on: (1) the 1:50,000-scale (nominal) aerial photographs on which they are based, with an estimated potential error due to a pen line width of approximately 0.001 being equivalent to approximately 1.5 meters on the ground; (2) the accuracy of the human zoom transfer scope operator in tracing the linework from acetate overlays to topographic base maps, with an estimated error due to a pen line width of approximately 0.001 being equivalent to approximately 1.5 meters on the ground; (3) the accuracy of the zoom transfer process itself, error magnitude highly variable and unknown but potentially large; (4) the digitizing RMS error of 0.003 inches [input coverage units], which equates to approximately 5 meters on the ground for a 1:63,360-scale map; (5) the accuracy of the human operator digitizing the geologic linework from the topographic base maps, with an estimated error due to a pen line width of approximately 0.001 being equivalent to approximately 1.5 meters on the ground; and (6) the accuracy of the topographic maps.

A standard pattern of sample and data acquisition was followed at each thermal area visited. At site with multiple springs, water samples were normally obtained from the thermal spring with the highest temperature and greatest discharge. Water samples were collected, filtered, and treated following procedures described in Presser and Barnes (1974).
