Hillshade of lidar acquired within the Pinto Mountain Fault Zone

The image shown displays a portion of the lidar data collected by the USGS for the SAFSOC Project. Our goal is to study and map surficial processes and landforms related to tectonism, specifically the San Andreas Fault system. With computer processing to remove vegetation, highly accurate, bare-earth digital elevation models of the ground surface are derived to aid in more

Upstream view of the Columbia River flowing through the Hanford reach

The Columbia River flowing through the Hanford reach of the arid Columbia River basin, eastern Washington. This reach is one of the few undammed segments of the Columbia River within the United States. Photograph taken from the White Bluffs, composed of sediment deposited in late Miocene and Pliocene Lake Ringold which occupied the Pasco Basin.

Geologic Map and Borehole Stratigraphy of Hinkley Valley and Vicinity, San Bernardino County, California
December 31, 2020

Geologic Map and Borehole Stratigraphy of Hinkley Valley and Vicinity,

Hinkley Valley, in the central to western Mojave Desert of southeastern California, has a long historical record owing to its position as a crossroads for rail and road traffic and its position adjacent to the Mojave River. Subflow in the Mojave River provided groundwater recharge that maintained water consumption and demand by way of shallow wells for local agriculture in

Flight area for Trans-Pecos aeromagnetic and radiometric survey

Map indicating flight area for Trans-Pecos aeromagnetic and radiometric survey. The survey area includes parts of El Paso and Hudspeth counties, Texas, and Otero County, New Mexico. Flights will begin in November 2020 and are expected to conclude in mid-January 2021.

Confluence of the Deschutes and Columbia rivers

An enigmatic outcrop of 5 million year old basalt sits 300 meters above the Deschutes and Columbia rivers. USGS scientists are carefully studying this basalt flow to determine if it came all the way from central Oregon, 160 kilometers away.

Airborne Radiometric Maps of Mountain Pass, California

Geophysical investigations of Mountain Pass, California, were conducted as part of an effort to study regional crustal structures as an aid to understanding the geologic framework and mineral resources of the eastern Mojave Desert. The study area encompasses Mountain Pass, which is host to one of the world’s largest rare earth element (REE) carbonatite deposits. The

Rain clouds and red sky over the Northern Bristol Mountains in the Mojave Desert, California
February 14, 2019

Twilight in the Northern Bristol Mountains

Rain clouds at twilight over the Norhtern Bristol Mountains. THese types of winter storms provide water to the desert ecosystem, but are not usually intense enough to transport sediment or do other geomorphic work. This image was captured during geologic mapping of surficial geologic materials in order to better understand the Quaternary (younger than ~2.5 million years)

Lineations on a strand of the Soda-Avawatz Fault Zone northern Soda Mt

Lineations on a vertical fault strand of the Soda-Avawatz Fault Zone, exposed in the northern Soda Mountains, Mojave Desert, southern California. The fault can be seen cutting both late Tertiary sand and gravel units, but is buried by an overlying mid-Pleistocene alluvial gravel deposit.
