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, California. These data support modeling of gravity and magnetic anomalies to understand the structure beneath the southern Klamath Mountains.
