The data contained in this report were gathered as part of a hydrothermal reconnaissance of the State of Utah. These data, plus additional data and information, will form the basis for a future interpretive report. These data are being released separately from and prior to the interpretive report, to make them available to interested parties at the earliest possible time.
Table 1 contains temperature-profile data for 30 wells; their general locations are shown in figure 1. The well locations were estimated from aerial photographs and topographic maps; no effort was made to survey the sites and as a result some locations may be slightly in error.
Temperatures were measured using thermistor, 4-conductor cable, and a digital multimeter. Meter readings were in ohms, but were converted to temperature by a calibration graph. The electronic thermometer is capable of an accuracy to 0.01°C, and readings were so recorded. Because of variations in field conditions, the temperature data in many wells probably is accurate only to 0.1°C. Depths below land surface were measured using a sheave and attached counter. Depths are generally accurate to the nearest foot.
