With insufficient food, and uncertainty whether he could negotiate the ice between himself and land, he made the best possible dash and barely escaped with his life from the melting ice. On April 20, he was no farther north than 86°30' latitude. This latitude was never published by Peary. It is in a typescript of his April 1906 diary, discovered by Wally Herbert in his assessment commissioned by the National Geographic Society. The typescript suddenly stopped there, one day before Peary's April 21 purported "farthest". The original of the April 1906 record is the only missing diary of Peary's exploration career. He claimed the next day to have achieved a Farthest North world record at 87°06' and returned to 86°30' without camping. This implied a trip of at least between sleeping, even assuming direct travel with no detours.
