The Mount Frakes is a probably extinct shield volcano in the West Antarctic Marie Byrd Land . At 3,654 m, it is the highest mountain in the Crary Mountains and forms a coherent unit with Mount Steere and Mount Rees , two other volcanoes. The Boyd Ridge ridge in the southeast completes the ridge of the Crary Mountains, which runs roughly in a northwest-southeastern direction.
Mount Frakes was formed from about 4.25 million years BP. The volcanic activity extended intermittently over a long period into the late Pleistocene ; a rock sample from a flank volcano on the southwest side of the mountain is only about 30,000 years old.
The United States Geological Survey mapped it on the basis of its own measurements and aerial photographs of the United States Navy from the years 1959 to 1966. The Advisory Committee on Antarctic Names named the mountain after the American geologist Lawrence Austin Frakes (* 1930), who in the frame of the United States Antarctic Program from 1964 to 1968 in three summer campaigns in the Falkland Islands and Antarctica .
