Three hills in the active volcanic zone of the Reykjanes peninsula, SW‐Iceland, are largely composed of volcanic tuffs and thin lava flows having stable, shallow reverse directions of magnetization. These hills are most probably contemporaneous and of late Wisconsinan age. Their mean virtual pole position is at 254°E, 12°S. Along with a geomagnetic event of similar age recently discovered elsewhere in SW‐Iceland, this excursion may define a useful stratigraphic horizon in studies of the Mid‐Atlantic ridge crest in Iceland.
