Geosciences and Environmental Change Science Center
GECSC researchers conduct multi-purpose geologic mapping and topical scientific studies to address issues concerning geologic, climatic, ecosystem, and land surface changes; human interactions with the environment; and physical, chemical, and biological characterization of the Earth's surface and upper crust.
Today, the U.S. Geological Survey (USGS) and the U.S. Department of Energy (DOE), in partnership with DOE’s Lawrence Berkeley National Laboratory and the American Wind Energy Association, released the United States Wind Turbine Database (USWTDB) and the USWTDB Viewer to access this new public dataset.
Bringing together decades of research and mapping, the U.S. Geological Survey just released a geologic map and companion pamphlet featuring the Arkansas River Valley region in north-central Colorado.
A new tool that gives users the most detailed view yet of the world’s mountains is now available from the USGS. And it’s as close as your computer or cellphone.
Geologic map of the Leadville North 7.5’ quadrangle, Eagle and Lake Counties, Colorado
The Leadville North 7.5’ quadrangle lies at the northern end of the Upper Arkansas Valley, where the Continental Divide at Tennessee Pass creates a low drainage divide between the Colorado and Arkansas River watersheds. In the eastern half of the quadrangle, the Paleozoic sedimentary section dips generally 20–30 degrees east. At Tennessee Pass and...Ruleman, Chester A.; Brandt, Theodore R.; Caffee, Marc W.; Goehring, Brent M.
Geologic map of the Weldona 7.5′ quadrangle, Morgan County, Colorado
The Weldona 7.5′ quadrangle is located on the semiarid plains of northeastern Colorado, along the South Platte River corridor where the river has incised into Upper Cretaceous Pierre Shale. The Pierre Shale is largely covered by surficial deposits that formed from alluvial, eolian, and hillslope processes operating in concert with environmental...Berry, Margaret E.; Taylor, Emily M.; Slate, Janet L.; Paces, James B.; Hanson, Paul R.; Brandt, Theodore R.
Geochemistry and mineralogy of late Quaternary loess in the upper Mississippi River valley, USA: Provenance and correlation with Laurentide Ice Sheet history
The midcontinent of North America contains some of the thickest and most extensive last-glacial loess deposits in the world, known as Peoria Loess. Peoria Loess of the upper Mississippi River valley region is thought to have had temporally varying glaciogenic sources resulting from inputs of sediment to the Mississippi River from different lobes...Muhs, Daniel; Bettis, E.
