Operation Highjump and the Richard E. Byrd Diary Controversy

Record summary

Operation Highjump was a real United States Antarctic expedition led by Richard E. Byrd, while a purported “secret diary” describing an interior polar world circulated in later paranormal and hollow-Earth literature. This lead permits comparison between authenticated expedition documentation, fabricated or misattributed texts, and myth-making around inaccessible landscapes. The operation itself involved naval logistics, mapping and training, not verified subterranean encounters. Researchers should trace the diary’s publication history, manuscript provenance and differences from Byrd’s known public writings.
