Two out-of-print geologic and mineral assessment reports on Piute and Garfield Counties are reproduced on CD in PDF format. Texts with plates are in one file for easy viewing; plates are a higher resolution and formatted for easy plotting are in separate files. Data contained in the reports must be viewed in light of their publication date and constraints of the period; some geologic units have been reclassified, some resource potentials have been drastically altered by changing economic/availability changes, etc. The publications on this CD are listed below: B-102 Mineral resource potential of Piute County, Utah and adjoining area, by E. Callaghan, 1973 B-107 Geology and mineral resources of Garfield County, Utah, by H. H. Doelling, 1975
