The Ambarkanta map in which the sea of Helcar is located where mordor is located in the later maps is from 1930! At that time there were no Hobbits, no ring, no Mordor. In UT it is stated that the Druedain passed south of Mordor and then turning north in the First Age. Also, there are references in Home to the Sea of Rhun in the first age prving that the Ambarkanta map had become invalid after the LotR was written.
