Abstract

Under Contract No. 14-08-0001-15727, awarded by the U.S. Geological Survey, Jim Feighny, of Loveland, Colo., drilled 42 test holes in the Williams Fork Mountains near Hayden, Colo., in September 1976. The area is referred to in the Contract as Yampa No. 3, which includes the Bureau of Land Management's (ELM) tracts WF-10, WF-12, WF-16, and WF-17. The purpose of the drilling was to obtain information on the quality and extent of the coal in the area. All holes were logged using either Gamma-Gamma (density), Natural Gamma, Caliper, Resistivity, or spontaneous-potential (SP) geophysical logs. The logging was done by the U.S. Geological Survey, the Birdwell Division of Seismograph Service Corp., Century Geophysical, and Geodynamics, Inc. The water level is indicated in table 1 for each drill hole at the time the hole was logged. All holes were drilled on private surface, and surface ownership is shown in table 1.
