Hodgson Nunatak
The Hudson Mountains are a mountain range in western Ellsworth Land just east of Cranton Bay and Pine Island Bay at the eastern extremity of Amundsen Sea. They are of volcanic origin, consisting of low scattered mountains and nunataks that protrude through the West Antarctic Ice Sheet. The Hudson Mountains are bounded on the north by Cosgrove Ice Shelf and on the south by Pine Island Glacier. Geology The Hudson Mountains contain slightly eroded parasitic cones that overlie three extensively eroded Miocene stratovolcanoes: Mount Manthe, Teeters Nunatak and Mount Moses. Potential steam was reported in 1974 and an unconfirmed report of an eruption detected by satellite was made in 1985, indicating that the Hudson Mountains may be volcanically active. Volcanic activity of the Hudson Mountains has produced predominantly subaerial basaltic lava flows, although subglacial or subaqueous tuffs and lava flows have also been noted.

Mount Moses
Mount Moses () is, at , the highest and most prominent of the Hudson Mountains of Antarctica, located near the center of the group, about north-northeast of Mount Manthe. It was mapped from air photos taken by U.S. Navy Operation Highjump in 1946–47, and was named by the Advisory Committee on Antarctic Names for Robert L. Moses, a geomagnetist and seismologist at Byrd Station in 1967.
