Geological summary
Mount Morning is a glaciated, undissected, alkalic shield volcano in the Erebus volcanic province SE of the south end of the Royal Society Range. An elongated 4.9 x 4.1 km caldera lies at the summit, and numerous lava domes and cinder cones formed on fissures on the N, NE, and SE flanks. The latest volcanism associated with growth of the phonolitic central volcano was Potassium-Argon dated at about 1.2 to 1 million years, and late-Pleistocene to zero-age Argon-Argon dates were obtained for some of the volumetrically dominant basanitic fissure vents. More than 50 morphologically youthful vents occur on the flanks.
From Wikipedia
Mount Morning is a shield volcano at the foot of the Transantarctic Mountains in Victoria Land, Antarctica. It lies 100 kilometres (62 mi) from Ross Island. Mount Morning rises to an elevation of 2,723 metres (8,934 ft) and is almost entirely mantled with snow and ice. A 4.1-by-4.9-kilometre-wide summit caldera lies at the top of the volcano, and several ice-free ridges such as Hurricane Ridge and Riviera Ridge emanate from the summit. A number of parasitic vents mainly in the form of cinder cones dot the mountain.
