Marith Reheis
My entire post-graduate career has been in the USGS in Denver, migrating from Conservation to Geologic Division early on, and then residing in the evolving branches of Regional Geology -- Environmental Geology -- Climate Change -- Earth Surface Processes Team. In parallel, my career has evolved through bedrock and surficial mapping, soil studies, neotectonics, desert dust sampling and a

A quarter-million years of paleoenvironmental change at Bear Lake, Utah and Idaho A quarter-million years of paleoenvironmental change at Bear Lake, Utah and Idaho
A continuous, 120-m-long core (BL00-1) from Bear Lake, Utah and Idaho, contains evidence of hydrologic and environmental change over the last two glacial-interglacial cycles. The core was taken at 41.95??N, 111.31??W, near the depocenter of the 60-m-deep, spring-fed, alkaline lake, where carbonate-bearing sediment has accumulated continuously. Chronological control is poor but indicates...

Compositions of modern dust and surface sediments in the Desert Southwest, United States Compositions of modern dust and surface sediments in the Desert Southwest, United States
Modern dusts across southwestern United States deserts are compositionally similar to dust-rich Av soil horizons (depths of 0-0.5 cm and 1-4 cm at 35 sites) for common crustal elements but distinctly different for some trace elements. Chemical compositions and magnetic properties of the soil samples are similar among sites relative to dust sources, geographic areas, and lithologic...

Lake Manix shorelines and Afton Canyon terraces: Implications for incision of Afton Canyon Lake Manix shorelines and Afton Canyon terraces: Implications for incision of Afton Canyon
Lake Manix, in south-central California, was the terminal basin of the Mojave River until the late Pleistocene, when it drained east to the Lake Mojave Basin. Based on new field observations, radiocarbon ages, and soil development, we propose modifications to previously published hypotheses on the timing of the last 543 m above sea level (masl) highstand of Lake Manix, the timing of the...

Compositional trends in aeolian dust along a transect across the southwestern United States Compositional trends in aeolian dust along a transect across the southwestern United States
Aeolian dust strongly influences ecology and landscape geochemistry over large areas that span several desert ecosystems of the southwestern United States. This study evaluates spatial and temporal variations and trends of the physical and chemical properties of dust in the southwestern United States by examining dust deposited in natural depressions on high isolated surfaces along a...

Geochemical evidence for airborne dust additions to soils in Channel Islands National Park, California Geochemical evidence for airborne dust additions to soils in Channel Islands National Park, California
There is an increasing awareness that dust plays important roles in climate change, biogeochemical cycles, nutrient supply to ecosystems, and soil formation. In Channel Islands National Park, California, soils are clay-rich Vertisols or Alfisols and Mollisols with vertic properties. The soils are overlain by silt-rich mantles that contrast sharply with the underlying clay-rich horizons...

The 2007 field trip of the Pacific Cell, Friends of the Pleistocene, visited features of the Quaternary geology and geomorphology of the Lake Manix basin in the Mojave Desert. This report is the guidebook for this trip and includes some discussion of relations observable along the road and at various field trip stops. The Mojave River originates in the San Bernardino Mountains and in...

Physical and Chemical Data from Eolian Sediment Collected Along a Transect from the Mojave Desert to the Colorado Plateau Physical and Chemical Data from Eolian Sediment Collected Along a Transect from the Mojave Desert to the Colorado Plateau
This report presents data and describes the methodology for magnetic, geochemical, and textural measurements of sediment and bedrock samples collected along a transect across the Southwestern United States (fig. 1). The results presented here support a study that examines compositional variations of mineral dust deposited during the past few centuries in isolated natural traps spanning a...

Airborne dust transport to the eastern Pacific Ocean off southern California: Evidence from San Clemente Island Airborne dust transport to the eastern Pacific Ocean off southern California: Evidence from San Clemente Island
Islands are natural dust traps, and San Clemente Island, California, is a good example. Soils on marine terraces cut into Miocene andesite on this island are clay-rich Vertisols or Alfisols with vertic properties. These soils are overlain by silt-rich mantles, 5-20 cm thick, that contrast sharply with the underlying clay-rich subsoils. The silt mantles have a mineralogy that is distinct...

Dust emission from wet and dry playas in the Mojave Desert, USA Dust emission from wet and dry playas in the Mojave Desert, USA
The interactions between playa hydrology and playa-surface sediments are important factors that control the type and amount of dust emitted from playas as a result of wind erosion. The production of evaporite minerals during evaporative loss of near-surface ground water results in both the creation and maintenance of several centimeters or more of loose sediment on and near the surfaces...

Temporal variations in slip rate of the White Mountain Fault Zone, Eastern California Temporal variations in slip rate of the White Mountain Fault Zone, Eastern California
The evolution of fault slip through time may yield insight into the geodynamics of deforming lithosphere. Precise determination of temporal variations in fault slip is often hindered, however, by a dearth of markers of varying age from which to reconstruct fault slip. Here we determine slip rates across the White Mountain Fault Zone over the past ca. 0.8??Ma from displaced alluvial...
