I was now anxious to find a suitable location for our Main Base; two reasons making it an urgent matter. The first was, that as we advanced to the west we were leaving the South Magnetic Pole, and I was anxious to have our magnetographs running as near the latter as possible. Secondly, we would be daily increasing our distance from Macquarie Island, making wireless communication more uncertain.
At noon on January 8, while I was weighing the pros and cons with Captain Davis, Wild came in to say that there was a rocky exposure about fifteen miles off on the port side, and suggested altering our course to obtain a better view of it.
Just after 4 P.M., when the ship was about one mile from the nearest rocks, the whale-boat was lowered and manned. We rowed in with the object of making a closer investigation. From the ship's deck, even when within a mile, the outcrop had appeared to project directly from under the inland ice-sheet. Now, however, we were surprised to find ourselves amongst an archipelago of islets. These were named the Mackellar Islets, in remembrance of one who had proved a staunch friend of the Expedition.
Weddell seals and Adelie penguins in thousands rested upon the rocks; the latter chiefly congregated upon a long, low, bare islet situated in the centre. This was the largest of the group, measuring about half a mile in length; others were not above twenty yards in diameter. As we came inshore, the main body of the archipelago was found to be separated by a mile and a half from the mainland. A point which struck us at the time was that the islets situated on the southern side of the group were capped by unique masses of ice; resembling iced cakes. Later we were able to see them in process of formation. In the violent southerly hurricanes prevalent in Adelie Land, the spray breaks right over them. Part of it is deposited and frozen, and by increments the icing of these monstrous "cakes" is built up. The amount contributed in winter makes up for loss by thawing in midsummer. As the islets to windward shelter those in their lee, the latter are destitute of these natural canopies.
Soundings were taken at frequent intervals with a hand lead-line, manipulated by Madigan. The water was on the whole shallow, varying from a few to twenty fathoms. The bottom was clothed by dense, luxuriant seaweed. This rank growth along the littoral was unexpected, for nothing of the kind exists on the Ross Sea coasts within five or six fathoms of the surface.
Advancing towards the mainland, we observed a small islet amongst the rocks, and towards it the boat was directed. We were soon inside a beautiful, miniature harbour completely land-locked. The sun shone gloriously in a blue sky as we stepped ashore on a charming ice-quay—the first to set foot on the Antarctic continent between Cape Adare and Gaussberg, a distance of one thousand eight hundred miles.
Wild and I proceeded to make a tour of exploration. The rocky area at Cape Denison, as it was named, was found to be about one mile in length and half a mile in extreme width. Behind it rose the inland ice, ascending in a regular slope and apparently free of crevasses—an outlet for our sledging parties in the event of the sea not firmly freezing over. To right and left of this oasis, as the visitor to Adelie Land must regard the welcome rock, the ice was heavily crevassed and fell sheer to the sea in cliffs, sixty to one hundred and fifty feet in height. Two small dark patches in the distance were the only evidences of rock to relieve the white monotony of the coast.
In landing cargo on Antarctic shores, advantage is generally taken of the floe-ice on to which the materials can be unloaded and at once sledged away to their destination. Here, on the other hand, there was open water, too shallow for the 'Aurora' to be moored alongside the ice-foot. The only alternative was to anchor the ship at a distance and discharge the cargo by boats running to the ideal harbour we had discovered. Close to the boat harbour was suitable ground for the erection of a hut, so that the various impedimenta would have to be carried only a short distance. For supplies of fresh meat, in the emergency of being marooned for a number of years, there were many Weddell seals at hand, and on almost all the neighbouring ridges colonies of penguins were busy rearing their young.64
