If you buy the idea that REH was influenced by Scott-Elliot's maps for the Thurian Age, then you might have a large continental Atlantis with it's eastern side being the Mid-Atlantic Ridge and it's western edge being the eastern US seaboard/Appalachians. This would be in contrast to a later smaller "Poseidonis" insular Atlantis. If so then you have, from left to right, Lemuria/Mu (Pacific), Pictish Isles (Rocky Mts.), Atlantean continent, then proto-Eurasia/Thurian Continent, without a whole lot of open ocean between land masses (plus plenty of islands presumably, as well as Kaa-u in there somewhere).
Hey Theagenes! I have to say that (IMO) Howard was only vaguely influenced by S-E's maps (though I think the influence was definitely there). REH's Atlantis doesn't seem particularly large (I'd say Australia-size, maybe a little bigger, tops). Spence never tried to imply that the western Atlantean littoral was anchored on the Appalachians. IMO, the Appalachians are where the "Kelts" Howard referred to (and the "pre-Indians" of The Dwellers Beneath the Tombs) originated/dwelt.
Between the "Appalachian Isles" and the Pictish Isles one has a lot of open water. But, it would appear that the "northern horn" of the "Southern Continent" (referenced in MotS) would provide an easy port for any mariners voyaging betwixt the two archipelagoes.
If the Lemurian Isles were anchored on the east by Hawaii and on the west by Ponape, then a Lemurian voyage/raid to the Isles of Sunset wouldn't be anything notable. There's evidence that Hawaiian mariners visited the Californian littoral numerous times.
Kaa-u would be represented by "Caribbean" isles such as Bal-Sagoth and Mogar.
