Bear Lake Water Quality
Bear Lake, located approximately 50 kilometers (km) northeast of Logan, Utah, straddles the Utah-Idaho border and is nestled in a graben valley between the Bear Lake Plateau on the east and the Bear River Range on the west (Reheis and others, 2009). Its calcium carbonate type water is a brilliant green-blue color that, in combination with sandy beaches and easy access, draws thousands of...
Groundwater Conditions in Utah
Small amounts of groundwater can be obtained from wells throughout most of Utah, but large amounts that are of suitable chemical quality for irrigation, public supply, or industrial use generally can be obtained only in specific ares. Most wells in Utah yield water from unconsolidated basin-fill deposits, and most are in intermountain basins that have been partly filled with rock materials...
Streamflow Information Program
The U.S. Geological Survey (USGS) operates and maintains a national network of about 8,000 streamgages (2018) to provide long-term, accurate, and unbiased streamflow information (often called discharge) to meet the multiple needs of many diverse users. Streamflow information is fundamental to national and local economic well-being, protection of life and property, and efficient and effective...
Volcanic-related Beryllium Deposits of the US: Geologic Setting, Genesis, and the Potential for Post-Extraction Recovery of By-Product Critical Minerals
Project objectives are: 1) to fully establish a comprehensive and robust geologic and geochemical framework for the occurrence of volcanic-related beryllium (Be) deposits; 2) further our understanding of the fundamental ore processes that lead to formation of volcanogenic beryllium (Be)-boron (B)-lithium (Li)-phosphorus (P) group deposits, by investigating processes favorable for enhanced...
Cheatgrass and Medusahead
Invasive annual grasses, such as cheatgrass (Bromus tectorum) and medusahead (Taeniatherum caput-medusae), are one of the most significant stressors to rangeland ecosystems in the western U.S. Their expansion and dominance across this area are the most damaging ecosystem agents on this iconic landscape.

Topographic maps are a signature product of the USGS. They were essential for integrating and analyzing place-based information, and were widely used by receationalists. After 125-year legacy of topographic mapping (1884-2009), the USGS embarked on an innovative future of integrating historical maps with computer-generated maps from a national geographical information system (GIS) database.
The 3DEP products and services available through The National Map consist of standard digital elevation models (DEMs) at various horizontal resolutions, elevation source and associated datasets, an elevation point query service and bulk point query service. All 3DEP products are available, free of charge and without use restrictions.

The 1934 Ms 6.6 Hansel Valley, Utah, earthquake produced an 8-km-long by 3-km-wide zone of north-south−trending surface deformation in an extensional basin within the easternmost Basin and Range Province. Less than 0.5 m of purely vertical displacement was measured at the surface, although seismologic data suggest mostly strike-slip faulting at...
Bruno, Pier Paolo G.; Duross, Christopher; Kokkalas, Sotirios Holocene surface-faulting earthquakes at the Spring Lake and North Creek Sites on the Wasatch Fault Zone: Evidence for complex rupture of the Nephi Segment
The Nephi segment of the Wasatch fault zone (WFZ) comprises two fault strands, the northern and southern strands, which have evidence of recurrent late Holocene surface-faulting earthquakes. We excavated paleoseismic trenches across these strands to refine and expand their Holocene earthquake chronologies; improve estimates of earthquake...

The history of late holocene surface-faulting earthquakes on the central segments of the Wasatch fault zone, Utah
The Wasatch fault (WFZ)—Utah’s longest and most active normal fault—forms a prominent eastern boundary to the Basin and Range Province in northern Utah. To provide paleoseismic data for a Wasatch Front regional earthquake forecast, we synthesized paleoseismic data to define the timing and displacements of late Holocene surface-faulting earthquakes...
Duross, Christopher; Personius, Stephen; Olig, Susan S; Crone, Anthony J.; Hylland, Michael D.; Lund, William R.; Schwartz, David P. Fault segmentation: New concepts from the Wasatch Fault Zone, Utah, USA
The question of whether structural segment boundaries along multisegment normal faults such as the Wasatch fault zone (WFZ) act as persistent barriers to rupture is critical to seismic hazard analyses. We synthesized late Holocene paleoseismic data from 20 trench sites along the central WFZ to evaluate earthquake rupture length and fault...

In a letter to The Salt Lake Daily Tribune in September 1883, U.S. Geological Survey (USGS) geologist G.K.

Case History: An adult female Great-Horned Owl (Bobo virginianus) was found dead in a residential yard in Utah, U.S. with an immature male Eurasian Collared-Dove (Streptopelia decaocto) clutched in its left foot.
A new assessment of groundwater resources in the Spanish Valley watershed in southern Utah shows an amount that is about 30–40% lower than previously reported, according to a U.S. Geological Survey report.
A new study shows that mysterious cycles in salinity in the lower Colorado River are a result of precipitation patterns in the headwaters of the upper basin more than a thousand river miles away. The salinity levels generally repeat about every 10 years.
Mercury concentrations within Lake Powell are highest in side canyons within the lower portion of the reservoir, according to a new U.S. Geological Survey report. This finding is part of a study to better understand why mercury concentrations in striped bass are higher in the lower part of the reservoir.
Recovery of vegetation on plugged and abandoned oil and gas well sites on the Colorado Plateau is influenced by time, moisture, nonnative plants and the type of plant community that was originally in place before well sites were constructed, according to a recently published study by the U.S. Geological Survey.
To understand plant genetic diversity and adaptations, scientist often conduct “common garden” experiments growing plants with diverse origins under the same soil and climatic conditions. However, most common garden studies may be too short to detect adaptive differences. Understanding climate adaptation of Wyoming Big Sagebrush could improve restoration strategies and success.
