The Surprise Spur ( English for surprise spur ) is a prominent rock spur in the West Antarctic Marie Byrd Land . He is the northernmost of three spurs on the southwest side of Ackerman Ridge in the La Gorce Mountains of Queen Maud Mountains .
The United States Geological Survey mapped it based on its own measurements and aerial photographs of the United States Navy from 1960 to 1961. Scientists from a campaign carried out from 1969 to 1970 as part of the New Zealand Geological Survey Antarctic Expedition named him. It is named after the fact that the spur, in contrast to the basement of this spur, consists of the geologically much younger sediments of the so-called beacon sandstone .
