This article is about the mountain range in the Atlantis series. For the range in the elves' world in "Coming Across," see Green Mountains. The Green Ridge Mountains were the sole mountain range of the continent of Atlantis. They began in the northern most tip of the continent and ran southerly, effectively dividing the continent in half. Nonetheless, Atlanteans generally preferred traveling by ship around the continent rather than over it. John James Audubon's 1843 excursion to Atlantis met success when he found a flock of rare agile honkers in a secluded valley in the Green Ridge Mountains.
