This bulletin serves not only to introduce the non-geologist to the rich geology of Millard County, but also to provide professional geologists with technical information on the stratigraphy, paleontology, and structural geology of the county. Millard County is unique among Utah’s counties in that it contains an exceptionally complete billion-year geologic record. This happened because until about 200 million years ago the area of present-day Millard County lay near sea level and was awash in shallow marine waters on a continental shelf upon which a stack of fossil-bearing strata more than 6 miles (10 km) thick slowly accumulated. This bulletin summarizes what is known about these strata, as well as younger rocks and surficial deposits in the county, and provides references to scientific papers that describe them in greater detail. Mountains North 30 x 60 (1:100,000-scale) quadrangles. These companion maps and this bulletin portray the geology of Millard County more completely and accurately than any previously published work.

This report describes the nongeothermal hydrogeologic system of the Cove Creek basin and an adjoining part of the Beaver River basin north of Milford, in Millard and Beaver Counties, Utah. The groundwater system in the study area hosts two commercial geothermal reservoirs, provides the entire agricultural and culinary water supply, and may be connected with groundwater in adjoining basins. The report presents a regional hydrogeologic framework assessment, including a newly compiled 1:100,000-scale geologic map, five schematic cross sections, estimates of thickness and hydrologic character of the basin fill based on geophysics and available well logs, and a new potentiometric surface map for the study area. The report also presents and interprets new and compiled geochemical and isotopic data and a new water budget for the study area that includes estimates of subsurface flow to adjoining basins. 65 pages + 2 plates

The Pony Express basaltic ash is locally a useful stratigraphic marker in Lake Bonneville sediments in west-central Utah. The ash was erupted from a vent in the Sevier Desert basin soon after Lake Bonneville had transgressed high enough to flood into the basin about 24,000 years ago. The ash is found at or near the base of the Bonneville marl below altitudes of 1400m (4600 ft) in part of the Sevier Desert basin and the southernmost part of the Great Salt Lake basin. The chemical composition of the ash is similar to that of other basalts in the Sevier Desert. Possible source vents are in the Pahvant Butte area or a maar near Smelter Knolls.

Lake Bonneville: A Scientific Update showcases new information and interpretations about this important lake in the North American Great Basin, presenting a relatively complete summary of the evolving scientific ideas about the Pleistocene lake. A comprehensive book on Lake Bonneville has not been published since the masterpiece of G.K. Gilbert in 1890. Because of Gilbert's work, Lake Bonneville has been the starting point for many studies of Quaternary paleolakes in many places throughout the world. Numerous journal articles, and a few books on specialized topics related to Lake Bonneville, have been published since the late 1800s, but here the editors compile the important data and perspectives of the early 21st century into a book that will be an essential reference for future generations. Scientific research on Lake Bonneville is vibrant today and will continue into the future. - Makes the widespread and detailed literature on this well-known Pleistocene body of water accessible - Gives expositions of the many famous and iconic landforms and deposits - Contains over 300 illustrations, most in full color - Contains chapters on many important topics, including stratigraphy, sedimentology, hydrology, geomorphology, geochronology, isostasy, geophysics, geochemistry, vegetation history, pollen, fishes, mammals, mountain glaciation, prehistoric humans, paleoclimate, remote sensing, and geoantiquities in the Bonneville basin

The U.S. Environmental Protection Agency has recommended that states develop Pesticide Management Plans for four agricultural chemicals - alachlor, atrazine, metolachlor, and simazine - used in Utah as herbicides in the production of corn and sorghum, and to control weeds and undesired vegetation (such as along right-of-ways or utility substations). This report and accompanying maps are intended to be used as part of these Pesticide Management Plans to provide local, state, and federal government agencies and agricultural pesticide users with a base of information concerning sensitivity and vulnerability of ground water in the basin-fill aquifer (bedrock is not evaluated) to agricultural pesticides in the southern Sevier Desert and Pahvant Valley, Millard County, Utah. We used existing data to produce pesticide sensitivity and vulnerability maps by applying an attribute ranking system specifically tailored to the western United States using Geographic Information System analysis methods. 28 pages + 2 plates

A bibliography of Utah geothermal references through 1984. These references which directly pertain to a geothermal resources are annotated. The annotations are intended to inform the reader of the information contained in the article, not to summarize the results. Accompanying the bibliography is a list and description of geothermal projects and commercial geothermal developments in Utah from 1966 to the present that have been wholly or partially funded through Federal or State programs. The references listed in the project descriptions are keyed to the bibliography. Most of this work is by government agencies or universities. Private or industry-funded geothermal developments are not listed. The references are indexed geographically either under 1.) United States (national studies), 2.) regional – western United States or physiographic province, 3.) Utah – statewide and regional, or 4.) county. Reports concerning a particular hot spring or thermal area are listed under both the thermal area and the county names.
