The term "Sandeidet Moraine" is not a widely recognized or formally established geographical or geological entity in standard encyclopedic sources or international gazetteers.
"Sandeidet" is a Norwegian geographical name meaning "the sand isthmus" or "the sand pass." In established geographic records, Sandeidet refers to a specific flat-bottomed pass located between the Conrad Mountains and the Dallmann Mountains within the Orvin Mountains of Queen Maud Land, Antarctica. This feature was first mapped by Norwegian cartographers from surveys and air photos taken during the Sixth Norwegian Antarctic Expedition (1956–60).
While the region of Sandeidet is characterized by glacial activity, and moraines (accumulations of debris deposited by a glacier) are common features in such environments, there is no specific landform officially designated as the "Sandeidet Moraine" in major geographical databases, such as the Scientific Committee on Antarctic Research (SCAR) Composite Gazetteer of Antarctica or the United States Geological Survey (USGS) Geographic Names Information System.
