Transit Reef

50 km east of Helen Reef (Palau) is Transit Reef (Pieraurou), which appears on some maps and which is referenced as an island in the Hatohobei State constitution and constitutes the southermost feature of Palau. Its existence, however, is doubtful, as it is not listed in the current Sailing Directions. The literal translation of its Tobian name Pieraurou is "Sandy Navigation Point", referring to a submerged sand bar rather than a reef or island.
