appear symmetrical from all points of view. The base is less than 20 miles in 
diameter, and the mountain, though 8000 feet high, is not nearly so voluminous as 
Mount Erebus or Mount Terror. 
Basalts* appear to be developed at its base, and but few parasitic vents or obvious 
lava-flows are seen upon its sides. The only specimens brought back by the 
‘Discovery’ Expedition are rounded pumice-fragments (899). These were obtained 
from the floating ice of Wood Bay, and must have been transported by the wind 
during the winter months. 
Between Cape Washington and Cape Bernacchi, or in other words between 
Mount Melbourne and Mount Evans, no volcanic cone has been noted. This is 
important when we remember that here the foothills are absent, and that the coast is 
straight and uniform for a distance of over 200 miles. South of Cape Bernacchi, 
foothills composed of gneissic rocks are developed for some 50 miles. These are 
separated from Mount Morning and Mount Discovery by the valley of the Koettlitz 
Glacier, which' trends north-west and lies parallel to a line joining the two 
volcanoes. 
Mount Morning. 
Mount Morning is a low dome 5779 feet high, and is almost circular. At 
its base it is 10 miles in diameter. On the south side the mountain slopes down 
to sea-level, and on the south-west it is separated from the main ranges by low 
foothills. The Koettlitz Glacier, which opens out north-eastward, occupies part of the 
above-mentioned depression between foothills and mountain -range. Radiating lava- 
flows are a prominent feature of this mountain, but no specimens could be obtained 
from them. 
Mount Discovery. 
Mount Discovery, the last volcanic cone which we shall note, is 9085 feet high, 
and lies in latitude 78|° S., longitude 165° E. (Fig. 32, p. 58). It adjoins Mount 
Morning on the west, but is cut oft' from the nearest mainland by Discovery Gulf, 
the ice-filled gulf into which the Koettlitz Glacier flows. The mountain is 
symmetrical in outline and has the form of a bell. The inflected curves of its sides 
unite at the summit without indicating the presence of a crater, and they spread out 
to give the mountain a circular base, some 15 miles in diameter at sea-level. This 
mountain was not visited, but the moraines stranded in the land-locked bay on its 
north-east side show that basaltic fragments are the commonest ejectamenta. 
The Minna Bluff. 
The Minna Bluff is a long and narrow promontory which projects south-eastward 
from the foot of Mount Discovery. It seldom attains a height of more than 2000 feet. 
It is 35 miles long, but its breadth is rarely greater than 5 miles. Its sides are
