In May 2025, the U.S. Geological Survey (USGS) National Uncrewed Systems Office (NUSO) conducted uncrewed aircraft system (UAS) flights to collect hyperspectral and thermal remote sensing imagery over dryland sites during a collaborative field campaign near Moab, Utah. Two sites, "Horsethief Campground" and "Salt Valley", which have differing vegetation and soil characteristics, were...

Laminated soil carbonate rinds are a Quaternary paleoclimate archive whose isotope composition is linked to soil formation conditions. At Rio Mesa, Utah (USA), we investigated the fidelity of rind records in a river terrace setting by determining the seasonal timing of rind formation and testing for inter-record replication. We infer soil carbonate formed in the spring season...

Radiometric data were collected at the Grand Junction Regional Airport radiometric calibration facility in March 2023 and August 2024. The facility consists of five ~9 by ~12 m (30 x 40 feet) concrete pads, each 18 in thick. Each pad provides sources of radioelements that are spatially homogeneous (see Ward, 1978). Three pads are dedicated K, Th, and U pads, each of which contains high...

Examining urban thermal environments has become a critical area of research spanning epidemiology, urban planning, and ecology. While traditional metrics like air temperature (Tair) and satellite-derived surface temperature (SD-LST) dominate urban heat studies, these measures often fail to reflect how people actually experience thermal exposure intensity. More human-oriented metrics...

This report and accompanying maps and database address the geologic and geophysical character of a block of ten 7.5’ quadrangles that span the San Gorgonio Pass region. The study culminates more than four decades of intermittent geologic and geophysical mapping investigations by the U.S. Geological Survey (USGS). Published results from these investigations fall into two categories: (1)...

In several early studies, central California marine terraces between Santa Barbara and Point Conception were interpreted to record sea-level high stands of the last interglacial complex, ~80 ka to ~120 ka (marine isotope stage [MIS] 5). These ages and their elevations (~20 m to ~45 m) indicate modest rates of tectonic uplift, similar to those from other localities in southern and central

Rivers are some of the most dynamic features of the Arctic landscape, yet their role in the global carbon cycle is poorly understood. Researchers are still unraveling the intricacies of how river dynamics control organic carbon (OC) accumulation, transport, and degradation in riverine systems. The interplay between permafrost thermal state in river corridors, snow and ice-affected...

These Holocene aged samples are from three sediment cores obtained near the Provincetown Hook spit in Cape Cod, Massachusetts. The goal of the geochronology work is to determine when shoreface sediments, which represent the oceanward extent of the spit, were present at the surface for the Provincetown Hook. Results from this work support efforts to publish more recent sedimentological...

This data release contains paleoecological records from Santa Fe Lake, NM USA. Santa Fe Lake is a small (1.4 ha), subalpine lake in the Sangre de Cristo Mountain Range of the Southern Rocky Mountains (35.79°N, 105.78°W, 3532 m a.s.l). Overlapping sediment cores were taken from Santa Fe Lake in September, 2020 in 5.4 m of water from a coring platform with a Livingstone square-rod piston...

This dataset presents a recalculated compilation of geochronology ages of Cretaceous-Miocene intrusive rocks and volcanic plugs in the northern Rocky Mountains USA, with a focus on Montana and Idaho. Mineral assessments and prospectivity mapping requires detailed spatiotemporal understanding of magma systems in the upper crust to predict when and where ore deposits may have formed...

This digital dataset was created as part of a U.S. Geological Survey (USGS) regional groundwater assessment of the eastern Great Basin; the project was called the Great Basin Carbonate-Alluvial Aquifer Study (GBCAAS). The study area has a geographic extent of 110,000 square miles, predominantly in eastern Nevada and western Utah. As part of this larger study, the USGS developed digital...

This geologic map area of 5,430 km2 spans a reach of the lower Missouri River valley and adjoining uplands for about 100 kilometers east of Gavins Point Dam, the easternmost mainstem dam on the Missouri River. Understanding the surficial geologic history of the valley is relevant to natural resource management of the Missouri National Recreational River and is foundational to improved
