Zircon U-Pb data for Paleoproterozoic metasedimentary rocks of the Gunnison block, central Colorado, USA
This data release includes raw detrital zircon U-Pb data for Paleoproterozoic metasedimentary rocks of the Gunnison block, central Colorado, USA. Detrital zircon U-Pb data for five samples of metasedimentary rock (totaling 1459 zircon U-Pb dates) were acquired via laser ablation-inductively coupled
Data-model files associated with the manuscript "The Effects of Spatial and Temporal Resolution of Gridded Meteorological Forcing on Watershed Hydrological Responses"
This data package contains the model inputs and outputs used in "The Effects of Spatial and Temporal Resolution of Gridded Meteorological Forcing on Watershed Hydrological Responses" (Shuai et al., 2022 HESS). The data.zip file contains the data used to drive the model simulations. The model.zip fil
Database for the Geologic Map of the Bonanza Caldera Area, Northeastern San Juan Mountains, Colorado
The San Juan Mountains in southwestern Colorado have long been recognized as a site of exceptionally voluminous mid-Tertiary volcanism, including at least 24 major ignimbrite sheets (each 150-5,000 km3) and associated caldera structures active at 33-23 Ma. More recent volcanologic and petrologic stu

Selected geologic data for the shallow groundwater system in the Lower Gunnison River Basin, Colorado
This point dataset contains geologic information concerning regolith thickness and top-of-bedrock altitude at selected well and test-hole locations in the Lower Gunnison River Basin in Delta, Montrose, Ouray, and Gunnison Counties, Colorado. Regolith-thickness data were compiled from lithologic logs

Regolith-thickness contours for the shallow groundwater system in the Lower Gunnison River Basin, Colorado
This dataset consists of isopach contours showing the generalized thickness of regolith sediments (alluvium, colluvium, and weathered bedrock) overlying well-consolidated bedrock in the Lower Gunnison River Basin in Delta, Montrose, Ouray, and Gunnison Counties, Colorado. Regolith thickness was cont
Geologic and aeromagnetic maps of the Fossil Ridge area and vicinity, Gunnison County, Colorado
This data set includes a GIS geologic map database of an Early Proterozoic metavolcanic and metasedimentary terrane extensively intruded by Early and Middle Proterozoic granitic plutons. Laramide to Tertiary deformation and intrusion of felsic plutons have created numerous small mineral deposits tha
