Trends in snow water equivalent in Rocky Mountain National Park and the northern Front Range of Colorado, USA
Contributor:Patterson, Glenn G.
The seasonal snowpack in Rocky Mountain National Park and the northern Front Range of Colorado, USA, within 50 km of the park, is undergoing changes that will pose challenges for water providers, natural resource managers, ...
Landslide response to climate change in Denali National Park, Alaska, and other permafrost regions

Automated event detectors utilized for continental intraplate earthquakes : applications to tectonic, induced, and magmatic sequences
Contributor:McMahon, Nicole D.
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 ...
Relative influences of valley geometry and wood on sediment distribution in Biscuit Brook, NY
Contributor:Hinshaw, Sarah Kathleen
Sediment storage in mountain streams is commonly associated with level of valley confinement. In unconfined channels, sediment is stored in the floodplain and active channel in a network of secondary channels with abundant ...
Monitoring the effectiveness of river realignment on the Upper Colorado River, Rocky Mountain National Park
A 2003 debris flow introduced 36,000 m3 of sediment into a high-elevation wetland on the Upper Colorado River in Rocky Mountain National Park. In September 2015, Park staff built an earthen diversion dam and realigned a ...
Petrogenetic analysis of the Wenatchee Ridge Orthogneiss in the North Cascade Mountains, Washington State
Contributor:Zaggle, Richard Haster
Petrogenetic analysis of the Wenatchee Ridge Orthogneiss (WRO) in the Nason Terrane of the North Cascade Mountains has been undertaken in order to gain insight into epidote-bearing TTG plutonism associated with mid-Cretaceous ...
Investigating the carbonate-shale facies transition and deposition on the Scandinavian Ordovician Shelf – the Arnestad Formation, southern Norway
Contributor:Schuller, Kathryn M.
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 ...
Snow persistence and hydrologic response across the intermittent-persistent snow transition
Contributor:Hammond, John Christopher
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 ...
Evidence for Fluid-Assisted Shear Failure in a Ductile Shear Zone : Tectonic Tremor in the Geologic Record?
Recent direct observations of tectonic tremor below the seismogenic zone of large fault zones have emphasized the significance of coeval ductile and brittle processes at high temperatures. Tectonic tremor is defined as ...
Evaluating subalpine lake delta carbon storage in the Colorado Front Range and Washington Central Cascades
Mountainous regions are important contributors to the terrestrial organic carbon (OC) sink that affect global climate through the regulation of carbon-based greenhouse gases. However, mountain OC dynamics are poorly ...
