Good Glacier [SEP] continent
Good Glacier
Good Glacier () is a wide glacier draining the eastern slopes of the Hughes Range in Antarctica between Mount Brennan and Mount Waterman and flowing northeast to enter the Ross Ice Shelf to the east of Mount Reinhardt. It was discovered by the United States Antarctic Service on Flight C of February 29 – March 1, 1940, and named by the Advisory Committee on Antarctic Names, on the recommendation of Rear Admiral Richard E. Byrd, for Vice Admiral Roscoe F. Good, U.S. Navy, who furnished assistance and support for
continental crust, forming large rift basins that would ultimately fail to split the continent. Eventually, this sunken region of Laurentia was flooded with a shallow seaway that extended from at least present-day Lake Superior to Glacier National Park in Montana to the Grand Canyon and the Uinta Mountains. The resulting Grand Canyon Supergroup of sedimentary units is composed of nine varied geologic formations that were laid down from 1.2 billion and 740 million years ago in this sea. Good exposures of the supergroup can be seen in eastern Grand Canyon in
