Principal facts for 63 gravity stations in the vicinity of Katmai National Park, Alaska
Saltus RW. 1992. Principal facts for 63 gravity stations in the vicinity of Katmai National Park, Alaska. U.S. Geological Survey (USGS) Open-File Report. 92-310. United States Geological Survey. Denver
This report describes data for 63 gravity measurements made in July 1991 in the vicinity of Katmai National Park and the town of King Salmon, Alaska. The measurements were made with Lacoste and Romberg gravity meter G-17C. Elevation control is from mapped spot elevations and altimetry. Included in this report are base station descriptions for two new gravity bases established in King Salmon. Tables in the report list principal facts and reduced Bouguer and isostatic residual gravity anomalies. Page-sized plots at 1:250,000 scale show the measurement site locations. A page-sized contour plot of the complete Bouguer anomaly in the vicinity of Katmai Pass shows a gravity low that may be caused by low-density magma within the crust.
