Aeromagnetic, gravity anomaly, and derivative maps of the Craig and Dixon Entrance 1°x3° quadrangles of southeastern Alaska

A simplified geologic map, raw gravity and magnetic data, with derivative products including depth-to-source and rock densities, with limited interpretations of the underlying geology, structures, and mineral resources.

An interpretation of the aeromagnetic and gravity data and derivative maps of the Craig and Dixon Entrance 1-degree by 3-degree quadrangles and the western edges of the Ketchikan and Prince Rupert quadrangles, Southeastern Alaska

Preliminary geologic map of the northeast Dillingham quadrangle (D-1, D-2, C-1, and C-2), Alaska

Map, report, and geospatial data on the geology of the northeastern part of the 1:250,000 scale Dillingham quadrangle, Alaska. Includes Ar40/39 radiometric ages, geologic unit descriptions, and correlation of map units.
