Geology of Badlands National Park: A preliminary report Geology of Badlands National Park: A preliminary report

Badlands National Park is host to perhaps the most scenic geology and landscape features in the Western Interior region of the United States. Ongoing erosion that forms the "badlands" exposes ancient sedimentary strata of Late Cretaceous through Oligocene age. Quaternary erosional and depositional processes are responsible for most of the modern landscape features in the park and...

Principal facts for gravity stations in the Dry Valley area, west-central Nevada and east-central California Principal facts for gravity stations in the Dry Valley area, west-central Nevada and east-central California

In June, 2002, the U.S. Geological Survey (USGS) established 143 new gravity stations and 12 new rock samples in the Dry Valley area, 30 miles north of Reno, Nevada, on the California - Nevada border (see fig. 1). This study reports on gravity, magnetic, and physical property data intended for use in modeling the geometry and depth of Dry Valley for groundwater analysis. It is part of a...

Principal facts for 408 gravity stations in the vicinity of the Talkeetna Mountains, south-central Alaska Principal facts for 408 gravity stations in the vicinity of the Talkeetna Mountains, south-central Alaska

Gravity data were collected between 1999 and 2002 along transects in the Talkeetna Mountains of south-central Alaska as part of a geological and geophysical study of the framework geology of the region. The study area lies between 61° 30’ and 63° 45’ N. latitude and 145° and 151° W. longitude. This data set includes 408 gravity stations. These data, combined with the pre-existing 3,286...

Geochemistry of Permian rocks from the margins of the Phosphoria Basin: Lakeridge core, western Wyoming Geochemistry of Permian rocks from the margins of the Phosphoria Basin: Lakeridge core, western Wyoming

The Permian Phosphoria Formation and interbedded units of the Park City Formation and Shedhorn Sandstone in western Wyoming represent deposition along a carbonate ramp at the eastern margin of the Phosphoria Basin, with portions of the Phosphoria units reflecting periods of upwelling and widespread phosphogenesis. Thickness-weighted slab-samples of these units were collected at a maximum...

Preliminary soil-slip susceptibility maps, southwestern California Preliminary soil-slip susceptibility maps, southwestern California

This group of maps shows relative susceptibility of hill slopes to the initiation sites of rainfall-triggered soil slip-debris flows in southwestern California. As such, the maps offer a partial answer to one part of the three parts necessary to predict the soil-slip/debris-flow process. A complete prediction of the process would include assessments of “where”, “when”, and “how big”...

Correlation of the Klamath Mountains and Sierra Nevada Correlation of the Klamath Mountains and Sierra Nevada

This report graphically portrays the broadly parallel tectonic development of the Klamath Mountains and Sierra Nevada from early Paleozoic to Early Cretaceous time. It is dedicated to J.S. Diller of the U.S. Geological Survey who, during his pioneer field studies a century ago, recognized significant similarities between these two important provinces. The report is based mainly on the...
