Automated event detectors utilized for continental intraplate earthquakes : applications to tectonic, induced, and magmatic sequences

Contributor:McMahon, Nicole D.;
Date Submitted:2018

Event detection is a crucial part of the data-driven science of seismology. With decades of continuous seismic data recorded across thousands of networks and tens of thousands of stations, and an ever-accelerating rate of ...

Snow persistence and hydrologic response across the intermittent-persistent snow transition

Contributor:Hammond, John Christopher;
Date Submitted:2018

In mountainous regions and high latitudes, seasonal snow is a critical component of the surface energy balance and hydrologic cycle. Snowpacks have been declining in many mountain regions, but the hydrologic responses to ...

Hydrologic impacts of lined gravel pits, Colorado Front Range

Contributor:Rach, Gavin;
Date Submitted:2018

Sand and gravel quarries are a major source of natural aggregate. Gravel pits often excavate below the water table and therefore can influence alluvial aquifer groundwater flow directions and groundwater-surface water ...

Llama use on public lands

Contributor:Arndt, Cheryl Anne
Date Submitted:1988

Interest in utilizing llamas as packstock is affecting natural resource managers as requests to use llamas on federally-owned lands increases. To adopt effective management practices related to issues raised by this ...

Analyzing post-flood recovery after an extreme flood : North St. Vrain Creek, CO

Contributor:Eidmann, Johanna S.;
Date Submitted:2018

Assessing the ongoing sediment remobilization and deposition following an extreme flood is important for understanding disturbance response and recovery, and for addressing the challenges to water resource management. From ...

Hydrogeologic characterization of the Fountain Formation : prospective aquifer storage and recovery targets in Front Range Colorado

Contributor:Collazo, Daniel;
Date Submitted:2018

Aquifer storage and recovery (ASR) is a method of water storage that typically involves using the same well to inject water into and recover water from an aquifer. Benefits of ASR include lower capital costs than surface ...

Organic carbon storage in mountain river valley bottoms of the western United States

Contributor:Scott, Daniel N.;
Date Submitted:2018

Valley bottoms, which include river channels and associated floodplains, are important components of the terrestrial carbon sink. Downed wood and floodplain soil in valley bottoms act as transient pools of organic carbon ...

Floodplain organic carbon storage in the central Yukon River Basin, interior Alaska

Contributor:Lininger, Katherine Blom;
Date Submitted:2018

River channels and floodplains transport, transform, deposit, and store organic carbon (OC) as active participants in the carbon cycle. Two of the largest stocks of OC in floodplains include soil and downed large wood (LW). ...

Diagenesis and geochemistry of the Lower Permian Ingleside Formation, Owl Canyon area, Larimer County, Colorado

Contributor:Issa, Ahmad;
Date Submitted:2018

The purpose of this study is to determine the diagenetic history and timing of hydrocarbon migration in the Lower Permian Ingleside Formation as revealed in the Ingleside roadcut at Owl Canyon area, Colorado. The studied ...

Hydrothermal mineralization and alteration at the Globe Hill deposit, Cripple Creek district, Colorado

Contributor:Trippel, Alan D.;
Date Submitted:1985

The Globe Hill deposit is hosted by a porphyritic, subvolcanic intrusive which is composed of pyroxene-bearing alkali trachyte. It is emplaced within the Oligocene-age Cripple Creek diatreme-intrusive complex, which may ...

Contributor:Schuller, Kathryn M.;
Date Submitted:2018

The Upper Ordovician Arnestad Formation was located on the northwestern edge of Baltica in the region near modern day Oslo, Norway. This formation was found to be 60 m thick and consists of intercalated siliciclastic ...

Tracing hydrosocial change : the social constellations of water access and allocation for oil and gas development in Colorado

Contributor:Boone, Karie;
Date Submitted:2018

Increasing water use for OG development in Colorado suggests a change in the social constellations of water governance. Colorado's water allocation institutions, practices and policies relationally shape and are shaped by ...
