New gravity measurements in the vicinity of San Bernardino, Californiawere collected to help define the characteristics of the Rialto-Coltonfault. The data were processed using standard reduction formulas andparameters. Rock properties such as lithology, magnetic susceptibilityand density also were measured at several locations.

Gravity data were collected from 2016 through 2019 to assist in mapping surface and subsurface geology in the central Upper Peninsula of Michigan and in neighboring northeastern Wisconsin. This data release provides principal facts for 1536 new gravity stations that were acquired to supplement existing public gravity data coverage.

Gravity data were collected in August of 2019 at 21 sites on and around Iliamna Volcano and Anchorage, Alaska. Measurements were taken with a Lacoste & Romberg G-161 meter and reduced to obtain the complete Bouguer anomaly. A total of 39 magnetic susceptibility measurements were taken at 13 locations using a ZH Instruments SM30 susceptibility meter. This data release includes susceptibility measurements, processed gravity data, shapefiles with field locations, and site photos.

Gravity data were collected in 2016 and 2017 to assist in mapping subsurface geology in and around the eastern Adirondack highlands, northern New York, which host numerous iron-oxide apatite deposits. Many of these deposits contain rare-earth elements, which are considered a critical mineral resource. This data release provides principal facts for 189 new gravity stations that were acquired to fill in gaps in the existing public gravity data coverage.

Gravity data were compiled, collected, and edited to produce anisostatic gravity map of the Los Angeles 30 x 60 minutequadrangle, California. This record focuses primarily onthe principal facts, that is, gravity observations, and thecorrections made to those values to reflect the effects ofelevation and terrain, and deep crustal structure.
