The Filchner Rocks (-54.7°N -79°W) are a group of rocks, some of which are submerged, 4nmi northeast of Cape Vahsel, off the east end of South Georgia. The existence of these rocks was reported in 1775 by a British expedition under James Cook. They were charted by the Second German Antarctic Expedition, 1911–12, and named for Dr. Wilhelm Filchner, leader of the expedition.
