Manahan Peak
Manahan Peak () is a prominent peak east of Giggenbach Ridge in northeastern Ross Island, Antarctica. The peak rises to over northwest of the summit of Mount Terror. It was named by the Advisory Committee on Antarctic Names in 2000 after biologist Donal T. Manahan, who worked eight seasons in Antarctica from 1983. Manahan was the United States Antarctic Program principal investigator in a study of the early stages (embryos and larvae) of marine animals, and was chair of the Polar Research Board at the National Academy of Sciences in 2000.
