The Hudson Mountains, located along the Walgreen Coast in Antarctica's western Ellsworth Land, contain many only slightly eroded parasitic cones forming nunataks protruding above the Antarctic icecap. The cinder cones apparently rest on three extensively eroded Miocene stratovolcanoes, Teeters Nunatak, Mount Moses, and Mount Manthe. Subaerial basaltic lava flows dominate, but subglacial or subaqueous tuffs and lava flows are also present. A tephra layer from an eruption of a subglacial volcano in the Hudson Mountains was dated from ice thickness at about 200 BC. The possible presence of steam was reported at one of the Hudson volcanoes during 1974. Satellite data suggested that an eruption of Webber Nunatak took place during 1985, although this has not been confirmed (LeMasurier and Thomson, 1990).---
