Sixteen iron meteorites together weighing 320 kg were recovered from the north‐eastern flank of Derrick Peak, northern Britannia Range, Antarctica (156°30′E, 80°05′S), in December 1978. The well preserved meteorites rested cleanly upon an elevated, lag covered, glacially carved post‐Middle Miocene to Pliocene bench cut into Devonian orthoquartzites intruded by Jurassic dolerite, and at a lower elevation upon Middle Pleistocene glacial drifts. In considering that the irons are in situ, and based on drift correlations along the Transantarctic Mountains, a maximum terrestrial age of 200,000–300,000 years B.P. is favoured.
