The existence of high‐density, nearly‐structureless bedrock buried by relatively low‐density sediments makes gravity prospecting a very informative technique for bedrock‐topography studies of the northern Appalachian Plateaus. Locating bedrock exposures and using available well data reduces the area of the gravity search. Depths to bedrock from wells correlate excellently with depths from gravity anomalies. The minimum anomaly detected was 0·18 milligal, corresponding to a depth of approximately 40 feet.
