Excerpt from Geothermal Data of the United States: Including Many Original Determinations, of Underground Temperature
The purpose of this report is to present all available published data bearing on the rate of increase of underground temperature with increasing depth in the United States, together with several hundred original observations by myself and my associates. A canvass of the governmental, State, and serial publications has yielded many records of temperature of flowing wells and also a few observations made with thermometers in borings and deep mines. Additional data on temperature of flows have been given by correspondents. Some Of the data, especially those relating to flows from wells, may not be reliable, and as a rule these could not be discriminated. Many records are omitted because no facts are available as to the source of flow.
During extended investigations of the geology of underground waters in many parts Of the United States I and my assistants have had Opportunity to observe the temperature of flows and to sink thermometers in deep borings. One very important contribution has come from an associate, J. E. Todd, who recorded the temperature of flows from a large number of wells in central-eastern South Dakota.

Paperback. Zustand: New. Print on Demand. This book catalogs geothermal and temperature data collected from various sources in the United States by the author and fellow researchers. It includes over 200 temperature measurements from across the country, many of which were collected from several hundred feet below the surface. In choosing a range of geographical locations across the United States, the author sought to determine if there was a regional variation in the rate of temperature change relative to depth from the surface. This book makes a valuable contribution to the study of the Earth's thermal gradient and its implications for our understanding of the planet's inner workings.
