Presented are hydrologic data collected in northern Utah Valley from 1935 to 1982. The data include records of selected wells, springs, drains, irrigation ditches, streams, water quality, and drillers ' logs of selected wells. Some of the data were previously published by the Geological Survey and cooperating agencies. (USGS)

Listing of analytical results for rock, stream-sediment, water, and algae samples, calculated minimum thermal-reservoir temperatures, and the statistical summary of the analytical results for rock and stream-sediment samples, Charles Sheldon Wilderness Study Area, Humboldt and Washoe counties, Nevada, and Lake County, Oregon
A preliminary report on the stratigraphy of previously unreported Devonian ashfall localities in the Appalachian Basin
A photoelectric device has been built that automatically controls the analytical gap between electrodes during excitation period. The control device allows for precise control of the analytical gap during the arcing process of samples, resulting in better precision of analysis.
$ANBA is a program developed for rapid data acquisition and correction on an automated SEMQ electron microprobe. The program provides increased analytical speed and reduced disk read/write operations compared with the manufacturer's software, resulting in a doubling of analytical throughput. In addition, the program provides enhanced analytical features such as averaging, rapid and compact data storage, and on-line plotting. The program is described with design philosophy, flow charts, variable names, a complete program listing, and system requirements. A complete operating example and notes to assist in running the program are included.
The report contains 622 ground-water level measurements made in observation wells in Arkansas in the spring of 1985. In addition , the report contains well hydrographs relating to the Quaternary aquifer and the Sparta Sand aquifers, the most important aquifers with respect to ground-water availability and use in Arkansas.
