Mount Morning is a glaciated, undissected alkalic shield volcano in the Erebus volcanic province located SE of the south end of the Royal Society Range. An elongated 4.9 x 4.1 km wide caldera lies at the 2723-m-high summit, and numerous parasitic lava domes and flank cinder cones formed on fissures on the north, 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 mophologically youthful flank vents occur on the flanks of Mount Morning.

The Global Volcanism Program is not aware of any Holocene eruptions from Mount Morning. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Mount Morning page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Mount Morning shield volcano is seen in this aerial view from the NE. An ice-filled, elongated 4.9 x 4.1 km wide caldera lies at the 2723-m-high summit of the volcano. Numerous parasitic lava domes and flank cinder cones formed on fissures on Hurricane Ridge cutting across the NE flank at the middle right and on the Riviera Ridge beyond on the north flank.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
