An outcrop-scale brittle fault exposed on the shore of Lake Anna in the vicinity of the Dominion North Anna Power Plant.  The fault offsets a pegmatite dike within biotite granitic gneiss by about 1 meter, in a reserve (top-to-east) sense-of-motion.  The small fault is oriented 235°, with a dip of 30° to the northwest (view is to south in this photograph).

Treated wastewater from Joint Base Cape Cod was discharged to rapid-infiltration disposal beds from 1936 to 1995. The disposal formed a groundwater contamination plume that extends more than 10 kilometers in the Cape Cod sand and gravel glacial outwash aquifer.

Map showing the distribution of physiographic zones within the Buzzards Bay study area. The physiographic zone classification is adapted from Kelley and others (1998), and the zones are delineated on the basis of sea-floor morphology and the dominant texture of surficial material.

Split-beam (EK60) sonar image of bubbles (green) in the water column at a seep site overlooking Baltimore Canyon on the U.S. Atlantic margin. Although the bubbles appear to nearly reach the sea surface, the methane contained in the bubbles would have dissolved and been replaced by other gases by the time the bubbles rise several hundred meters.
