Temperature versus depth plots, calculated thermal gradients, and temperature logs are presented for 91 drill holes located in Alabama, Arkansas, California, Colorado, Illinois, Kansas, Louisiana, Michigan, Mississippi, Montana, New Mexico, New York, Oklahoma, Oregon, Pennsylvania, Texas, Utah, West Virginia, and Wyoming. These holes are selected from a much larger compilation of temperature data previously published by Spicer (1964). The selected subset consists of those holes that have been logged to depths generally greater than 600 m while at temperature equilibrium and that display conductive temperature gradients. Temperature gradients (/sup 0/C/km) calculated for each hole were used as part of the data base to produce a contoured temperature-gradient map of the conterminous United States in Guffanti and Nathenson (1980).
