Summary. Geomagnetic variation data from the north‐eastern United States, analysed using both the transfer function and the hypothetical event techniques, reveal the presence of a linear crustal conductivity anomaly. To the west of the New York–Vermont border, the anomaly runs parallel to a regional aeromagnetic lineament and it may be associated with a basement fracture zone. To the east, there is no obvious correlation with Appalachian tectonic structure but a kink in the axis of the anomaly correlates well with high heat flow in the White Mountains.
