This page, still under construction, describes Atlantis, the largest continent on the Atlantis Rise--the upside-down equivalent of our North Atlantic Ocean. Atlantis isn't huge--a tropical-to-temperate land about half the size of Europe or the USA. Its shores, especially in the east, are rugged fracture zones--an endless procession of cliffy heads, deep sounds, islands and shoals, all perpendicular to the deep rift zone offshore separating Atlantis from Azorea, the smaller eastern continent. New and casual visitors take note: these features aren't fantasy. They're inverted--up is down and down is up--but all these jagged landforms are there. Just hidden in the abyss.

Much of Earth's sea floor is poorly mapped even today, and shorelines on Abyssia are correspondingly uncertain. But our North Atlantic has had heavy shipping and study over the last century or five... Also, the Atlantic Rift between the twin continents creates jagged fracture zones. The result? I'm more confident of Atlantis's topography than most parts of Abyssia.

Names are based on local seamounts, trenches, fracture zones and abyssal plains. Some are inevitable, like Atlantis; some involved choice. For example, one of the two continents in the northern Atlantic has to be called Atlantis of course; but which? I chose the larger western one, mainly because four abyssal plains fuse to form it and if it's not Atlantis I'd have to decide between Nares, Hatteras, Sargassia or Sohm--or Suhm, as the panel certifying scientific names for such features says Sohm Abyssal Plain, found in most atlases, is a misspelling. By calling this western continent Atlantis and the eastern one Azorea, I can avoid all that. (Most of it. Sohm Plain or Suhm? I'll leave it Sohm for now.)

Judgment calls, yes--but like the landforms, none of the names are fantasy or purely arbitrary.

We tend to think of the abyss as a featureless muddy plain. The truth is that every new sonar sweep reveals more complexity; it's quite rugged down there. The parallel fjordlike bays serrating so many Abyssian coasts are the result of huge fracture zones.

The relief map below, of the land without vegetation, shows Azorea on the left and Atlantis on the right, with the Atlantic Deep snaking between them. (Spain's in the upper right, the Caribbean in the lower left). Lacy, crazy coasts like these repeat all over Abyssia--you can see why it took five years to finish the relief and painting of this globe!

Our sea-floor's peppered with volcanoes, far more than anyone expected. These are a bit of an scientific and esthetic problem on Abyssia--what's the tectonic explanation for all those conical pits? Abyssian geology would madden any Terran--but it's worth noting the reverse is true, too. Why not an active mantle with a lot of puckers where crust is crunched in a "downdraft", a world with rifts that pull inward instead of spreading? This isn't theoretical: puckers like this can be found on Venus ("inward" coronae), and the hottest convection system of all has lots of them: we call them sunspots. No volcanic cones on the sun!

Abyssia doesn't spew, it just sucks.

The most prominent example of these "puckerlakes" on Atlantis is in the northwest, around New England Sound. The "blue holes" in the sound and the equally deep lakes north of it are the inverted equivalent of Earth's New England Seamount Chain, which stretches from Cape Cod southeast for at least a thousand miles, at least to Congress and Lynch Seamounts). But this "puckerland" extends far beyond New England's latitude. Its culmination is arguably the deep blue hole of Bermuda Bay.

To the north... the Titanic Peninsula (near top) isn't called that for its size, but its history. No, you won't find a huge rusting steamship hulk high on the headlands:

However... all that said, we must have a Titanic here--more likely a sailing ship than a steamer, but a great ship just the same--titanic enough by Abyssian standards to merit the name. It snagged a reef off Cape Birma and sank with a great loss of life, enough to stamp its name on the vicinity.

Why must I let a sad tale from Earth spill over into Abyssia? Well, the region's nomenclature impels me. Not just Titanic itself, but Montmagny, Birma and Frankfurt are all names of Earthly sea features that commemorate the ships that hunted for survivors of the disaster.

Trapped by nomenclature! Not for the first time on Abyssia, either.

One more tiny Titanic item (Oh, how I enjoyed writing that phrase!)

On Terra, fossils of an extinct flightless bird that once roamed the forests of North America got named, purely for their size, Titanis. On Abyssia, an anologous flightless bird is not at all extinct, and lives in the forests of Atlantis. It's not surprising this Titanis survived when ours died out. Abyssian flightless birds have small forelimbs: they can use tools and brandish weapons; Stone Age mammalian savages had no advantage against them, and eventually found wary trade (or at least leaving those feisty, beaked, clawed neighbors alone) less costly than war.

It also helped that these mammals, on Atlantis, weren't fierce hairless apes adapted to cold and a nearly all-meat diet; instead they're leptaurs, omnivorous, savanna-bred, heat-loving, easy-going centauroids who just don't much want to live in cool, shady forests. The two species aren't competing to be top predator; their niches are different.

So in modern Atlantis, the two species coexist in a pattern that's seen all over Abyssia: flightless birds dominating rainforests, coasts and smaller islands, mammals dominating veldt, savanna and continental interiors--with much mixing and many exceptions.

Anyway,here in the northern woods and all down the rainy east coast, the majority of the population is literally (indeed, scientifically!) Titanic.

Purely a coincidence, I'm sure.

Atlantis's far north--the Laurentian Peninsula and the islands off its tip--isn't Abyssia's northernmost point: both Pacifica and Azorea extend several degrees further north, and of course the Lena Islands are polar (though possibly undiscovered, certainly uninhabited, and practically uninhabitable). But still, Laurentia's fourth; respectable on a world with little polar or even subpolar land.

So how cold is it? Not very. The north shore of the Laurentian Peninsula's barely reaches latitude 40°; only the Isle of Milne passes 45° north. Midway between pole and equator! And with no Greenland souring the climate, these are deep-forested lands with warm but not hot summers and cool rainy winters. True, occasionally you'll see snow, a rarity on Abyssia; but by our standards, it's mild.

The topography is gentle too; low, winding Appalachian ridges and broad plains. The islands and the spine of Laurentia are more rugged, reaching 1000 m in spots (3300'). The southeast coast is more ragged than the north, and fracture-zone fjords exist; but cliffs are lower, and it lacks the fractal madness seen to the south. Offshore, the Atlantis Rift is spreading, but more slowly here; and it shows.

The most impressive scenic attraction: the Big Trees. These close cousins to our Sierra Nevada sequoia have its shaggy, ruddy bark, but the coastal habitat, height and slimness of our coast redwood, with "flying buttresses" rather like swamp cypress or mangrove. From Cape Balanus on New England Sound, north to Cape Birma and east all the way to Cape Pico and the Isles of Newfoundland, groves of these monsters rise. In sheltered bottomlands they grow 400' tall.

Deserts are rare on Abyssia except for southwest Pacifica. So much of the sparse land elsewhere is maritime, and most mountains are too low to cast significant rainshadows. But Atlantis is an exception. The fourth largest continent, and perhaps the most continental of all--almost Earthlike in its compactness and continuity--Atlantis has enough inland inland to develop a true desert in the southwest, much like our North America does at a similar latitude.

Winds here in the Sargasso Desert tend to come from inland much of the year, off the Nares Mountains to the northeast. Storms can't come in from the south--they're blocked by the towering snowy Puerto Rico Range. Mt Milwaukee, at about 3900 meters (12,800'), is the highest point in this hemisphere. Yes, I meant it--that's the highest peak on half of Abyssia. Scenic, as tall as Fuji, but just a speedbump next to our Andes or Himalayas. Abyssia's land isn't just smaller in area than Earth; it's mostly low.

In summer, Atlantis's southwestern lowlands get so hot they create a local monsoon, drawing thunderstorms over the plains. These can be locally torrential but are inconsistent and brief overall. Rains in winter are sparse and rare except along the coast south of the Puerto Ricos.

The mountains, however, are quite pleasant; harvesting thundershowers in summer and snow in winter, they're temperate islands in the desert sea. And from the Puerto Ricos and even the Nares flow year-round creeks that fuse into the shallow, muddy, meandering Sargasso River, full of reedy islands and lined with trees; it wanders west over the dry plains to the sea, rather like our Senegal River... Map by Chris Wayan of southwestern Atlantis, a continent on Abyssia, an Earth where up is down and down is up.

Speaking of Senegal and desert borderlands... on Earth, most west coasts at the latitude of Blake Bay and Hatteras Plain are desert too. But the orbital photo shows they're only semi-arid: savanna, with some trees in the hills. Why's the Atlantean desert so small?

Prevailing winds in Hatteras don't come from the mountains or the Sargasso Desert (either one would guarantee us a Hatteras Desert nearly as big as the Sargasso), but from the northwest. No Rockies or Atlas Mountains to block storms--fronts roll off the great North Sea, across the Laurentian Peninsula, and then recharge over New England Sound and Bermuda Bay and Corner Sound.

The recipe for desert at this latitude isn't really west coast but land upwind. On Earth, they're usually the same--but not always on poor swiss-cheese Abyssia, full of holes where we have seamounts!

Turns out those puckers are good for something.

The islands off southwest Atlantis coast, plus the infrequency of storms, will encourage the development of boats; so I expect the Isle of Blake, Martinique and the Virgin Island to resemble the mainland culturally and biologically. The strait from Virgin to rugged Antille isn't much wider; its tall mountains will be visible on a good day. From Antille's south shore, the Aves Islands lead to huge Bonaire.

Two more great islands even bigger than Bonaire lie further offshore; but no hints of them will be visible from Bonaire or Antille; the Atlanteans will discover them much, much later, if at all. Still, I expect the nearer, Cayman, will be settled by Atlanteans native to this dry, mountainous southwest coast.

Who will these Atlanteans be? Well...

These savannas around the Sargasso Desert are the biggest in this hemisphere by far--so much of Abyssia's forest! That's had evolutionary consequences. Conditions in Hatteras, the Researcher Lakes, the Niños Hills, and especially the savannas around the Nares Lakes are as close to East Africa as we'll find in this hemisphere. That may lead to the evolution of an intelligent species. Probably not apes; remember that Abyssian mammals are best described as centauroid, so it isn't just bipeds and knuckle-walkers who have a free hand to explore tool use!

In the far hemisphere, I've pictured two such centauroids achieving intelligence: foxtaurs on Pacifica and equi on Agassiz to the south. Let's explore a third:

Here on Atlantis, social bands of leptaurs have discovered fire. They won't be obligate carnivores like our cats; hunting is hard and dangerous, so strict carnivores live short lives--a teenage lion is old. So while our leptaurs have builds and pelts a little like Terran leopards, the name's purely descriptive; they're omnivores. And there's plenty of omni to vore! The brushy, patchy savanna and woods of southwest Atlantis have tropical fruit trees, berry patches, nuts, greens, seeds parchable in campfires, shallow lakes full of crayfish and turtles... invent nets and snare birds, invent the hook and line and catch fish... why hunt big game?

My guess is they'll develop tools more to keep from being big game themselves--such savanna will have both midsize pack predators and big solitary hunters.

(But then, I'm a contrarian about human evolution too--I suspect defense not offense was the drive behind human weapons innovation. Lunch is never vital; not being lunch is. And that's shaped us; our childhood fear of monsters echoes a very long developmental stage. "Ontogeny recapitulates phylogeny" not just fetally, but psychologically. And we haven't yet fully outgrown that phase! At least some of us. Weapons and the demonization of enemies in war both grow from the ancestral terror of being devoured more than from a lust to devour. That's shallower and more recent: mere Ice Age atavism, recalling a time when some humans became top predators and turned highly carnivorous. But for millions of years, not mere thousands, fire and crude stone weapons were defenses, and we were still mostly herbivorous.)

Here are some (very) tentative sketches. Lots of variation. How much of that is diversity between subspecies, and how much my present uncertainty? Uh... both.

Intro - Names - Holes - NW Sounds - North - Titanis - Sargasso Desert - Leptaurs - The Eastern Fjords

All in good time, my pretty, all in good time! I did say this article was under construction... I'm currently combing through the GEBCO database of thousands of undersea names and features, one by one, to see if I can dredge up more names for some of these fjords and capes and lakes.

Overall, I'm finding that mapped and named features in this southeastern zone are much scanter than in the north. That's not the region's fault--it seems quite rugged and interesting. It's oceanographic bias. The north is closer to shipping lanes between European and American ports--and they, not tiny Caribbean islands, are the ones with the money for deepwater research. Every little hump off Portugal, the Azores and New York is named; not down here.

OK, the Researcher Deep surprised me. It's an impressive undersea mountain range on Earth--one of its peaks, Vayda, is taller than the Matterhorn, rising within a few hundred meters of the surface. On Abyssia, it's a hole about 4500 m (14,800') deep.

But it may not be an exception--just a region that one boat (the Researcher, logically enough) happened to map in detail. ALL the southeast may be like this! It's clearly scenic, even spectacular, with rugged ridges (even cliffs and scarps) along fracture zones as yet unnamed. Between them, freshwater lakes and great tropical fjords (full of jumbo shrimp and other tasty oxymorons, no doubt! But what else can I call such long, cliffwalled saltwater sounds?)

Altitude map by Chris Wayan of southeast Atlantis, a small continent with fractal coasts on Abyssia, an Earth where up is down and down is up. Plains are gold, hills orange, mountains red, water blue.
I apologize for the inconsistencies between the Southeast and Southwest maps. I brilliantly managed to destroy my master map of Atlantis, and had to redraw these maps from scratch, based on photos of my Abyssia globe (painted and molded to reflect data I lacked when first charting Atlantis). I think this map gives a more accurate picture of the eastern capes and fjords; the Southwest map is better at showing vegetation and implying climate belts. I need to re-consult some oceanic atlases before trying to reconcile the two.

Ecologically, what's this coast like? Oh, mostly warm and green--quite Floridian in the lowlands. But a Florida with cooler highlands atop spectacular cliffs. What's it like up there? Appalachia? Mexico? Roraima? Lots of equivalents of Angel Falls, that's for sure.

Aside from generous rainfall, how's the weather? Mild by Dixie standards--summers do see tropical storms, but fewer full-on Caribbean hurricanes: this Atlantic Sea is much narrower than ours, so storm-spirals have just a few days of warm water to feed on before they hit land and start to starve. It takes elbow room to brew a good hurricane--same as it takes a long "fetch" to generate big waves (there's a reason most great surfing's in the Pacific). And this shrunken and nearly landlocked Atlantic, no wider anywhere than our Gulf of Mexico, lacks the fetch to generate many big hurricanes.

Not that the leptaurs are crying over that. Dry cats are happy cats.
