Offshore geology and geomorphology from Point Piedras Blancas to Pismo Beach, San Luis Obispo County, California
Marine geology and geomorphology were mapped along the continental shelf and upper slope between Point Piedras Blancas and Pismo Beach, California. The map area is divided into the following three (smaller) map areas, listed from north to south: San Simeon, Morro Bay, and Point San Luis. Each smaller map area consists of a geologic map and the corresponding geophysical data that support the geolog

- Data
Gravity and physical property data, basin depth of the Hayfork graben, and horizontal gradient maxima of the southern Klamath Mountains, California
This data release contains principal facts of gravity measurements collected by the U.S. Geological Survey in 2013-2022, a compilation of existing and new density and magnetic susceptibility data, horizontal gradient maxima derived from gravity and magnetic potential fields, and depth of Cenozoic basin fill in the Hayfork basin from inversion of gravity data of the southern Klamath Mountains, CaliGravity data and geophysical gradient data of the Stockton 30 x 60 minute quadrangle, California
This data release presents point data associated with the geologic and geophysical maps of the Stockton 30 x 60 minute quadrangle, California. Data include principal fact information for new gravity measurements collected by the U.S. Geological Survey from 2015 to 2018 and for existing gravity data. Gravity and magnetic gradients were also calculated in the Stockton 30 x 60 minute quadrangle, CaliGravity and physical property data in the Chico and Willows 1:100,000-scale quadrangles, California
The datasets consist of principal fact information of gravity data and density and magnetic properties of hand samples in the Chico and Willows 1:100,000-scale quadrangles, California. - Maps

Geology along the Yuba Pass and Highway 70 corridors: A complex history of tectonics and magmatism in the northern Sierra Nevada
This field trip traverses a cross section of northern Sierra Nevada geology and landscape along two major corridors, Highway 49 (Yuba Pass) and Highway 70. These highways, and adjacent roadways, offer roadcuts, outcrops, and overviews through diverse pre-Cenozoic metamorphic rocks along the Laurentian margin, Mesozoic batholithic rocks, and Miocene volcanic rocks. Observing this array of rocks onAuthorsMichelle Roberts, Victoria Langenheim, Richard A. Schweickert, Richard E. Hanson
