Two or more deep crevasses in the Filchner Ice Shelf, extending W for an unknown distance from 37W, close W of Touchdown Hills. The feature is the most notable crevassed area on the Filchner Ice Shelf, roughly 60 mi long and from 0.25 to 3 mi wide. Discovered by the CTAE, 1955-58. During 1957 it was examined by a U.S. party from Ellsworth Station led by Dr. Edward Thiel, who applied the descriptive name. |
