Cape Evans is a low lava flow jutting out some three thousand feet from the face of the glaciers which clothe the slopes of Erebus. It is roughly an equilateral triangle in shape, at its base some three thousand feet (9⁄16th mile) across. This base-line, which divides the cape from the slopes of Erebus and the crevassed glaciers and giant ice-falls which clothe them, consists of a ramp with a slope of thirty degrees, and a varying height of some 100 to 150 feet. From our hut, four hundred yards away, it looks like a great embankment behind which rises the majestic volcano Erebus, with its plume of steam and smoke.
The cape itself does not rise on the average more than thirty feet, and somewhat resembles the back of a hog with several backbones. The hollows between the ridges are for the most part filled with snow and ice, while in one or two places where the accumulation of snow is great enough there are little glacierets which do not travel far before they ignominiously peter out. There are two small lakes, called Skua Lake and Island Lake respectively. There is only one hill which is almost behind the hut, and is called Wind Vane Hill, for on it were placed one of our wind vanes and certain other meteorological instruments. Into the glacieret which flowed down in the lee of this hill we drove two caves, which gave both an even low temperature and excellent insulation. One of them was therefore used for our magnetic observations, and the other as an ice-house for the mutton we had brought from New Zealand.
The north side, upon which we had built our hut, slopes down by way of a rubbly beach to the sea in North Bay. We knew there was a beach for we landed upon it, but we never saw it again even in the height of summer, for the winter blizzards formed an ice foot several feet thick. The other side of the cape ends abruptly in black bastions and baby cliffs some thirty feet high. The apex of the triangle which forms as it were the cape proper is a similar kenyte bluff. The whole makes a tricky place on which to walk in the dark, for the surface is strewn with boulders of all sizes and furrowed and channelled by drifts of hard and icy snow,
