Hudson Mountains volcanic field comprises about 20 volcanic nunataks. These are peaks protruding from ice, and here represent the surface expression of multiple volcanic vents. At least four nunataks can be seen faintly in this image, looking across the southern Hudson Mountains from the west. The exposed ridge in the left foreground is Webber Nunatak. The uppermost, largely ice-covered nunatak seen here is Mount Manthe, one of the largest peaks in this volcanic field and dated to about 5 million years ago. A tephra layer from this field was erupted about 2,000 years ago.
