This preliminary map is the first of several data compilations being prepared as a foundation for evaluating the mineral resource potential of Seward Peninsula. In addition to the sources of geologic data credited in the index map, Sainsbury's recent (1975) summary of his extensive geologic studies on Seward Peninsula has...

Five biostratigraphic zones based on the distribution of brachiopods and conodonts are proposed for the Park City Group. They are: the Peniculauris ivesi-Neostreptognathodus prayi Zone, the Peniculauris bassi-Neostreptognathodus sulcoplicatus Zone, the Peniculauris bassi-Neostreptognathodus sp. C Zone, the Thamnosia depressa Zone, and the Yakovlevia multistriata-Neogondolella bitteri Zone. They range in age...

The Gerster Limestone contains three minor lithofacies: the packstone, wackestone, and mixed facies, differentiated largely on the basis of the carbonate matrix and mud content of the rocks. Five biostratigraphic zones ranging in age from Roadian-Wordian to Wordian are, in ascending order, the Thamnosia, Kuvelousia, transition, Yakovlevia, and upper zones....

Long Meadow Lake, Black Dog Creek, and Ponds AP-9 and AP-10 which lie in an area designated for a trunk highway bridge crossing the Minnesota River, were sampled for baseline water quality prior to construction of the bridge. Data collected show that dissolved solids fluctuate seasonally. Dissolved oxygen:/ranged from less...

This report contains basic data on water-level measurements in observation wells in western Kansas. Most of the measurements were made in January 1977; a few were made in December 1976 and in February 1977. The measurements were made in mid-winter when pumping was minimal and water levels had recovered from...

The U.S. Geological Survey, in cooperation with the Rogue Valley Council of Governments, is studying surface-water-quality problems and their causes in the Bear Creek basin of southwestern Oregon. Two specific areas of investigation include: measurements of the quality and quantity of water in the irrigation canals and drainage system and...

More than 200 wells and springs were visited within a 20-mile radius of Coso Hot Springs, Calif. Hydrologic and geothermal data were collected for each well or spring site. The data includes depth, chemical quality, temperature and specific conductance of water, quantity of flow, well construction, and well logs. These...

The Barona and Capitan Grande Indian Reservations, California, have sufficient water to satisfy present (1976) domestic and stock needs; however, the Sycuan Indian Reservation is experiencing a shortage of water for domestic supply because of the decline of the water table beneath the reservation well field and a general decline...
