The highest point of Craddock Massif is Mount Rutford, a sharp peak that rises to 4,477 metres (14,688 ft).

[1] Sentinel Range was first sighted and photographed from the air on November 23, 1935, by Lincoln Ellsworth.

The entire range, including Craddock Massif, was mapped by the United States Geological Survey from aerial photography taken by the U.S. Navy, 1958–61.

The massif is named after Professor J. Campbell Craddock (1930–2006), the leader of the 1962–63 University of Minnesota geological expedition to the Sentinel and Heritage Ranges of the Ellsworth Mountains.
