The Castle Berg with dog Sledge
Photograph of ?Thomas Clissold (d. 1963), on a sledge pulled by a team of four dogs, in front of an iceberg.
This iceberg, which resembles a medieval castle, was greatly admired by members of the expedition. Ponting returned several times during 1911 to photograph it, including once in June, the middle of the Antarctic winter, when he set up flashlights to make an image. At its highest point the berg is around 100 feet high (30.5 m).
