A portrait photograph of the towering sheer ice-face of the stranded iceberg nicknamed the Castle Berg. Standing next to it in silhouette, looking up at the 'ramparts', is the expedition cook Thomas Clissold holding an ice-pick. On a later trip in October Clissold knocked himself out and suffered from concussion when he fell down the slope of the iceberg named 'The Matterhorn'. It prevented him from joining the Motor Party on the expedition south, as he had not fully recovered.

Ponting wrote about photographing this iceberg: 'As soon as possible after the sun returned I made some photographs of the Castle Berg, which had so entranced me since its arrival off our cape the previous autumn. The weathering process, to which it had been subjected by the winter storms, had but added to its wonder.'
