Social values for ecosystem services, version 3.0 (SolVES 3.0)—Documentation and user manual
By Ben Sherrouse and Darius Semmens. USGS Open-File Report 2015-1008.
SolVES is a geographic information system (GIS) tool developed by the GECSC. It can be used to incorporate quantified, spatially explicit social-values information into ecosystem service assessments. Among the updates included in the SolVES 3.0 release are new survey point weighting options and improved categorical data graphs. Accompanying this release is the revised documentation and user manual.

The new Cenozoic Landscape Evolution of the Southern Rocky
Mountains Project website gives an overview of mapping and research conducted by the GECSC and
collaborating USGS Science Centers. The project utilizes a combination of geologic mapping,
geophysical surveys, basin modeling, and structural, tectonic, neotectonic, geomorphic, volcanic,
stratigraphic, and geochronologic studies to better understand the evolution of the geologic
landscape of the southern Rocky Mountains province, which includes parts of Colorado, New Mexico,
and Wyoming. Besides providing information to help us better understand the geologic framework of
the region, many of the objectives of this project also address societal issues related to
groundwater management, geothermal and traditional energy resources, and geologic

Evidence for long-time scale (1000-year) changes in hydrothermal activity induced by seismic events
By Trevor Howald, Mark Person, Andrew Campbell, Virgil Luth, Albert Hofstra, Don Sweetkind (GECSC), Carl Gable, Amlan Banerjee, Elco Luijendijk, Laura Crossey, Karl Karlstrom, Shari Kelley, and Fred Phillips. Published in Geofluids.
The pollen 14C age and oxygen isotopic composition of siliceous sinter deposits from the former Beowawe geyser field reveal evidence of two hydrothermal discharge events that followed relatively low-magnitude earthquakes of Holocene and late Pleistocene age along the Malpais fault zone in Whirlwind Valley, Nevada. The model used suggests that the Malpais fault zone is composed of several pathways to the surface, each pathway having different fault zone apertures. As the most permeable conduit is sealed off by mineralization, alternative conduits are accessed along the Malpais fault.
