Mount Murphy in Western Antarctica

Mount Murphy is an 8-million-year-old volcano in the Antarctic. Experts have found evidence of “large-scale fluctuations” in the area ice sheet throughout the planet’s history due to “volcanic rocks, glaciogenic sediments and recycled marine microfossils” found at the site. It was named for noted Antarctic bird expert Robert Cushman Murphy of the American Museum of Natural History. Mount Murphy rises next to the Pine Island Glacier. NASA captured this landscape during a flight on Nov. 19, 2010.
