Steamboat Rock is a basalt "island" left over from the erosion during the glacial Missoula Floods.

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.

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.

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.

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. 

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.

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.
