Aqueous geochemical dynamics of metals and rare earth elements in an acid rock drainage-impacted alpine watershed (other)
Numerous mountain watersheds in the Colorado Mineral Belt (CMB) are impacted by acid rock drainage (ARD) and acid mine drainage (AMD), which mobilize metals and rare earth elements (REEs) into surface waters. In the upper Roaring Fork watershed near Independence Pass, natural ARD from a highly mineralized tributary is the primary source of acidity and element loading into Lincoln Creek, with additional contributions from historical mining at the Ruby Mine. Despite known concerns about metal transport, the fate of REEs remains poorly understood in this system and other similar watersheds. This study focuses on the behavior of major ions, trace metals, and REEs in surface waters along a flow path receiving ARD and AMD inputs. The objectives were to (1) evaluate the transport, mixing, and attenuation of major solutes and REEs across stream reaches, and (2) characterize REE geochemical signatures, including their redox behavior and utility as tracers in ARD/AMD impacted systems. Filtered water samples from six main sites were analyzed by Inductively-Coupled Plasma Mass Spectrometry (ICP-MS) and Ion Chromatography (IC) methods, and results were explored through mass balance transport calculations, bivariate plots, shale-normalized REE patterns, and the cerium anomaly. Water chemistry in the Lincoln Creek basin reveals distinct geochemical fingerprints for the Ruby Mine (enriched in Ca, Mg, Mn, and Cd) and the Mineralized Tributary (enriched in SO4, Fe, Al, and Cu), with several metals showing increasing trends in recent years. REE fractionation patterns and Ce anomalies further distinguish source contributions and processes, with the Mineralized Tributary displaying MREE enrichment from natural pyrite weathering and the Ruby Mine exhibiting HREE enrichment tied to mine-derived flows. Most solutes showed a mix of conservative and reactive transport depending on site and season, while certain late-season metal concentrations at the Grizzly Reservoir inlet exceeded aquatic life standards. These results indicate that source composition mainly controls major solute and REE patterns in surface waters, with reactive transport processes selectively influencing the behavior of certain elements. This thesis advances knowledge of metal and REE dynamics in high-elevation, ARD-affected watersheds and supports continued monitoring and management in the Lincoln Creek basin.

DWCZ - CO - Coal Creek - Soil Collection ICP - (DWCZ-MEF-CC-SoilSample-Transect-AWinkler) - (2022-2023) (other)
Locations: Coal Creek, which serves as the drinking water source for the town of Crested Butte, CO, receives both acid mine and acid rock drainage as a result of legacy mining and fractured porphyry networks, respectively. It has a Koppen climate class of Dfc, aka continental subarctic. Local ecology of the creek varies from site to site, with some parts being far more vegetative than others. Abstract: Acid mine drainage (AMD) and acid rock drainage (ARD) result in acidic, metal-laden solutions that seep into surface and groundwater systems. The hyporheic zone, where surface and groundwater meet, serves as a natural filtration system, where biogeochemical reactions occur that influence metal retention and transformation. By analyzing changes in metal concentrations and phases throughout time and space, valuable information can be gained in regards to the mechanisms at work within the hyporheic zone. Hyporheic sediment and sediment from planted control soil columns were sampled on a seasonal basis along Coal Creek, an area affected by both AMD and ARD. Samples were analyzed for phase changes via XRD and SEM and sequential extractions created using the samples were analyzed via ICP-OES for elemental fraction concentrations. Preliminary results show the retention and release of metals via redox chemistry. These changes are seasonally dynamic and vary from site to site along the creek, illustrating the capacity of the hyporheic zone to act as a filter for AMD at different points throughout the year.

Gothic (CO) Euphydryas gillettii vital rates 1981-1985, 2002-2004 (other)
Data were collected during July-September in 1981 through 1985 and during June-September 2002 through 2004. Mark-release-recapture was done for adult butterflies, and daily survival rate estimated for females using Jolly-Seber methods. Egg clusters were counted, along with number of eggs per cluster. Data were collected each year on egg cluster survival, and in 2004 on larval survival conditional on egg cluster survival. The data were used to construct yearly vital rates, including daily probability of laying an egg cluster, cluster size, survival from egg to diapause, survival over-winter to adult stage, and female daily survival probability. Population sizes were decreasing during nearly all years included in the data set, although a 1-2 order of magnitude increase in size occured ca. 2000-2, which is not included here.

DWCZ CO - Coal Creek (CC) (other)
Coal Creek (CC) is a high-elevation, headwater tributary to the Upper Colorado Basin located in the Ruby-Anthracite Range in the central Colorado Rocky Mountains. The CC watershed is 53 km2 in area and ranges in elevation from 2712 to 3668 meters. CC originates near Lake Irwin and enters the Slate River near the town of Crested Butte before joining East River and eventually the Gunnison River. The watershed is seasonally snow-covered from November through June. The average temperature is 0.9˚C and it receives around 670 mm of precipitation each year, about 66% of which falls as snow (Carroll et al, 2018). The remaining precipitation falls during the summer monsoon season (July through September). Although monsoon rains comprise nearly 40% of the annual precipitation, they contribute minimally to the streamflow because the moisture is taken up by vegetation and lost via evapotranspiration (Carroll et al, 2020). Vegetation in the basin is strongly aspect driven, with north facing aspects dominated by evergreen forest (65%) and south facing aspects dominated by deciduous (9%) and herbaceous (20%) vegetation. High elevation ridges are barren (3%) (Zhi et al, 2019). Discharge in CC is dominated by snowmelt, with average peak flow occurring in June in response to snowmelt. Flows recede throughout the summer and fall, with small peaks in flow due to monsoon events. CC reaches baseflow conditions by early September and they persist throughout the winter until the onset of snowmelt in April. The lower CC watershed is underlain predominately by sandstone (Mesaverde Formation) with glacial till deposits occurring near the streambed. The upper portion of the watershed is underlain by mafic intrusive plutonic rock, emplaced during the Middle Tertiary. Areas of the upper north slope of the watershed are underlain by mudstone (Wasatch Formation).
