On her way back to Ushaia, Tierra del Fuego, where she was due on December 30, the Lindblad Explorer passed by Wiencke Island, which lies between Anvers Island and the west coast of the Antarctic Peninsula. She was off Cape Astrup at the north-eastern end of the island when she ran aground. A sunken rock with less than 1.8m of water over it lies about 402m north of the cape.
