One twelfth of the Earth encompasses most of the South American continent, Puerto Rico, the Lesser Antilles, and the majority of Hispaniola—including southeastern Haiti and all but the northern coast of the Dominican Republic. This region, designated South America and the Eastern Isles, explicitly excludes Patagonia.

The northwestern boundary separates Panama, the southernmost country of Central America, from Colombia.

Within this world are the entirety of Venezuela, Guyana, Suriname, French Guiana, Brazil, Uruguay, Bolivia, and Peru. Argentina and Chile also belong largely to this region, though their sparsely populated southern reaches—Patagonia—are part of the subcontinent.

HistoryAtlas contains 2,652 entries for South America and the Eastern Isles from the Paleolithic period to 1899.

South America (49,293 – 28,578 BCE): Upper Pleistocene I — Refugia, Shelves, and the Two Southern Worlds

Geographic & Environmental Context

Late-Pleistocene South America was not one world but two adjoining worlds that barely overlapped:

• South America Major—from the Northern Andes (Quito–Cuzco–Titicaca–Altiplano) across the Amazon–Orinoco trunks, the Guianas Shield, and the Atlantic Brazil shelf, down through Paraguay–Uruguay–northern Argentina to northern Chile—was a continent of depressed cloud belts, fragmented rainforests, and broadened coastal plains.

• South America Minor—Patagonia, Tierra del Fuego, and the Magellan–Beagle archipelagos—was an ice-marginal realm of fjords, loess steppe, and shelf banks along two oceans, largely unpeopled at this time.

These natural subregions looked outward more than inward: South America Major was knit to the Pacific and Amazonian basins; South America Minor leaned into the Southern Ocean and subantarctic winds. Their contrasts anchor The Twelve Worlds claim that “region” is a loose envelope—the living units are the subregions.

Climate and Environmental Shifts

The interval spans the build-up to the Last Glacial Maximum:

• Andes & Altiplano: Temperatures were ~3–7 °C lower; glaciers expanded on high cordilleras; puna–páramo belts shifted downslope; springs and rock-shelter margins persisted.

• Amazon/Guianas: Rainforest contracted into riparian and montane refugia, separated by savanna corridors; evapotranspiration fell; seasonality sharpened.

• Atlantic Brazil shelf: Sea level ~100 m below modern exposed broad strand-plains; estuaries and deltas migrated seaward.

• Atacama & high basins: Hyper-arid, cold plateaus with oasis springs and small lagoons.

• Patagonia–Fuegia: Strong westerlies, permafrost or seasonal frost on the interior steppe; Cordilleran icefields calved into fjords; outer shelves widened on both coasts.

Heinrich/Dansgaard–Oeschger pulses toggled the continent between slightly wetter interstadials (refugia expand) and drier stadials (savannization and ice advance).

Lifeways and Settlement Patterns

Human presence before ~30 ka is debated. If present in this window, occupations were sparse and refugium-tethered; robust, widespread sites appear later, during deglaciation. The likely pattern:

• South America Major
  • Coasts (Pacific and Atlantic Brazil): Opportunistic foraging in upwelling coves and exposed strand-plains—shellfish, fish, seabirds—with short-stay dune or beach-ridge camps.
  • Riparian lowlands (Amazon–Orinoco): Small groups anchored to gallery forests and levees—fish, turtles, capybara, supplemented by deer/peccary and palm fruits.
  • Andean foothills & basins: Rock-shelter use near perennial springs; small-game, rodents, camelids at high elevations; wild tubers and chenopods along wet margins.
  • Atacama oases: Patchy use of springlines and saline lagoons where available.

• South America Minor
  • Likely unoccupied this early. Though kelp-forest corridors and rich fjord/shore ecologies existed (shellfish, pinnipeds, seabirds), sustained use is later (post-LGM, >14.5 ka north of the zone at Monte Verde).

Across the continent, potential foragers would have practiced short-radius mobility between water-secure nodes: coves ⇄ levees ⇄ springs ⇄ rock shelters.

Technology and Material Culture

Toolkits, where present, fit late Middle/early Upper Paleolithic expectations:

• Stone: expedient flake–blade industries in quartz/quartzite and local cherts; retouched scrapers, burins, backed pieces late.

• Organic: bone awls/points, digging sticks, nets/cordage (poorly preserved).

• Pigment & ornament: ochre for body/adhesive use; simple beads (shell/seed) in later parts of the span are plausible.

These reflect light, portable technologies optimized for riparian and springline mobility, not heavy residential investment.

Movement and Interaction Corridors

Even with low population density, the continent’s natural corridors were already set:

• Pacific littoral “kelp highway”: cove-to-cove reconnaissance along upwelling margins (Peru–N. Chile).

• Andean valley strings: spring/rock-shelter chains linking puna to foothills.

• Amazon–Orinoco trunks: Solimões–Madeira–Xingu–Tapajós–Negro and Orinoco–Casiquiare provided levee driftways and portage nodes.

• Atlantic strandlines: broad Brazilian shelf plains connected estuaries and lagoon belts.

In South America Minor, the Magellan–Beagle coasts and wide shelf banks were ecological scaffolding for the later maritime florescence.

Cultural and Symbolic Expressions

If present in this span, symbolic behaviors would mirror the global Upper Paleolithic repertoire at low intensity: ochre use, hearth structuring, simple ornament caches in shelters. The richest, unequivocal material appears after the interval, as deglaciation improves site survivorship and territory size.

Environmental Adaptation and Resilience

The operating logic of the age was refugium tethering:

• Water-secure nodes—gallery forests, springlines, upwelling coves—anchored seasonal rounds.

• Broad portfolios—aquatic + terrestrial—buffered aridity and cold snaps.

• Topographic stacking (coast ↔ foothill ↔ puna; levee ↔ terra firme) created short-range substitutes when one niche failed.

In South America Minor, kelp forests, guanaco steppe, and shelf banks formed the “later-use” safety net awaiting Holocene colonists.

Transition Toward Deglaciation

By 28,578 BCE, Andean ice began its slow retreat, rainforest corridors poised to reconnect, and coastal/riverine pathways to improve:

• South America Major was primed for the unequivocal Late Pleistocene/Early Holocene occupations—shell-midden coasts, levee hamlets, puna caravan trails—that will define its next chapter.

• South America Minor held its ecological stage set—fjords, archipelagos, and kelp lanes—for the post-LGM maritime foragers who would turn the far south into a canoe world.

In short, the continent already displayed the dual structure central to The Twelve Worlds: a peopled northern–central theater of refugia and corridors beside an unpeopled southern theater of ready-made ecologies—two neighboring worlds whose destinies would diverge as the ice let go.

South America Major (49,293–28,578 BCE)

South America Major includes Colombia (except Darién), Venezuela, the Guianas, Brazil, Ecuador (excluding the Capelands), Peru, Bolivia, Paraguay, Uruguay, northern Argentina, northern Chile.

Anchors: Northern Andes (Quito–Cuzco–Titicaca–Altiplano), Amazon Basin (Solimões–Madeira–Xingu–Tapajós–Marajó), Orinoco–Llanos, Atlantic Brazil coastal shelf, Guianas shield, Atacama oases.

Geographic & Environmental Context

• Andes: extensive glaciation on high cordilleras; puna and páramo belts depressed downslope.

• Amazon/Guianas: rainforest contracted into riparian and montane refugia, with intervening savanna corridors.

• Atlantic shelf: sea level ~100 m lower exposed broad coastal plains; estuaries migrated seaward.

• Atacama/Altiplano: cold, hyper-arid plateaus; oasis springs persistent.

Climate & Environmental Shifts

• Last Glacial Maximum (LGM): cooler (~3–7 °C lower), drier interiors; stronger seasonality; widespread glaciation in the Central Andes; reduced Amazonian evapotranspiration.

• Heinrich/D-O oscillations toggled between slightly wetter interstadials (refugia expand) and drier stadials (savannization).

Subsistence & Settlement

• Human presence before ~30 ka is debated (claims in eastern Brazil and Andean foothills exist but are contested). If present, foragers would have favored riparian refugia, coastal upwelling zones, and montane spring belts.

• Likeliest robust occupations in the later part of this window: coastal foraging (shellfish, fish, seabirds), riparian hunting (deer, peccary, capybara), and puna/basin small-game procurement.

Technology & Material Culture

• Late Middle/early Upper Paleolithic flake–blade industries; expedient quartz/quartzite; bone awls/points; ochre pigments.

• Portable organic technologies (nets, digging sticks) likely but poorly preserved.

Movement & Interaction Corridors

• Pacific littoral (upwelling coves, dune-sheltered landings), Andean valley strings (springs/rock shelters), Amazonian trunk rivers (Solimões–Madeira–Xingu–Tapajós), Orinoco–Casiquiare links to the Negro–Amazon.

Cultural & Symbolic Expressions

• If present, ochre and bead use, hearth structuring, and rock-shelter ritual spaces would mirror broader Upper Paleolithic patterns.

Environmental Adaptation & Resilience

• Refugium strategy: tethering to evergreen gallery forests, springlines, and productive coasts; broad-spectrum aquatic + terrestrial foraging buffered aridity.

Transition

• As deglaciation accelerates, rainforest corridors re-connect, Andean ice withdraws, and coastal/riverine pathways improve — enabling the unequivocal Late Pleistocene–Early Holocene occupations that follow.

South America Minor (49,293–28,578 BCE)

South America Minor includes southern Chile (incl. Central Valley), southern Argentina (Patagonia south of the Río Negro/Río Grande), Tierra del Fuego, Falkland/Malvinas, Juan Fernández.

Anchors: Patagonian steppe, Andean icefields, Strait of Magellan–Beagle Channel, Fuegian archipelago, Pacific fjords, Atlantic shelf banks.

Geographic & Environmental Context

• Cordilleran ice sheets dominated the southern Andes; outlet glaciers sculpted fjords and moraines.

• Patagonian steppe: cold, windy; periglacial dunes/loess.

• Sea-level lowstand exposed broad Atlantic shelves and expanded Magellan–Beagle shorelines.

Climate & Environmental Shifts

• LGM: strong westerlies, low temperatures, aridity inland; permafrost/seasonal frost common on steppe.

Subsistence & Settlement

• Human occupation in this early window is unlikely; robust evidence appears much later (>14.5 ka at Monte Verde to the north).

• Productive kelp highway ecologies existed (shellfish, pinnipeds, seabirds), but sustained use likely post-LGM.

Technology & Material Culture — N/A (pre-human).

Movement & Interaction Corridors — N/A (pre-human).

Cultural & Symbolic Expressions — N/A.

Environmental Adaptation & Resilience

• Ecological scaffolding (kelp forests, shelf banks, guanaco steppe) set the later human adaptive palette.

Transition

• Deglaciation and shelf flooding will open fjord/archipelago routes, enabling the well-documented Holocene maritime foragers of the southern cone.

Pedra Furada is the most controversial of the excavated prehistoric settlements in the Americas, indicating a human presence there as early as 50,000 BCE.

Pedra Furada ("drilled rock") is an important collection of over eight hundred archaeological sites and rock paintings in Brazil that suggest a human presence prior to the arrival of Clovis people in North America.

The discoveries are the subject of debate as they apparently contradict the "Clovis first" view for humans in the Americas, or short chronology theory, with the first movement beyond Alaska into the New World occurring no earlier than fifteen thousand to seventen thousand years ago, followed by successive waves of immigrants.

Pedra Furada provides arguments for the proponents of the long chronology theory, which states that the first group of people entered the hemisphere at a much earlier date, possibly twenty one thousand to forty thousand ears ago, with a much later mass secondary wave of immigrants.

Genetic studies of indigenous peoples have concluded that the "colonizing founders" of the Americas emerged from a single-source ancestral population that evolved in isolation, likely in Beringia.

The isolation in Beringia might have lasted ten thousand to twenty thousand years.

Age estimates based on Y-chromosome micro-satellite place diversity of the American Haplogroup Q1a3a (Y-DNA) at around ten thousand to fifteen thousand years ago.

This does not address if there were any previous failed colonization attempts by other genetic groups, which could be represented by those settling the Pedra Furada site, as genetic testing can only address current population ancestral heritage.

South America (28,577 – 7,822 BCE): Upper Pleistocene II → Early Holocene — Deglaciation, Reconnected Refugia, and Littoral Gateways

Geographic & Environmental Context

From the Quito–Cuzco–Titicaca–Altiplano to the Orinoco–Llanos, across the Amazon (Solimões–Madeira–Xingu–Tapajós–Marajó) and the Guianas Shield, and along the still-broadened Atlantic Brazil shelf and the upwelling coasts of Peru–northern Chile, South America entered the Early Holocene as a continent of rising mountains and rising seas.
In the south, South America Minor—Patagonia south of the Río Negro/Río Grande, the Strait of Magellan–Beagle Channel, Tierra del Fuego, and the Falkland/Malvinas–Juan Fernández outliers—saw Cordilleran icewithdraw into high cirques, carving fjord labyrinths west of the Andes and leaving proglacial lakes and steppe plateaus to the east.

Postglacial sea-level rise, still ~60–80 m below modern early in the period, flooded coastal benches into ria-like embayments and back-reef lagoons, particularly along Atlantic Brazil and the Caribbean margins, even as the Humboldt upwelling sustained kelp and shell-rich coves on the Pacific side.

Climate & Environmental Shifts

• Bølling–Allerød (c. 14.7–12.9 ka): Warmer, wetter pulses reforested Amazonian and Orinocan refugia, stitched by major river corridors; Andean hydroclimates stabilized as puna and páramo belts crept upslope. Along the Pacific rim, upwelling cells fueled rich nearshore webs; on the Atlantic side, a still-broad shelf supported expansive strandplains and lagoons.

• Younger Dryas (c. 12.9–11.7 ka): A cool/dry setback narrowed forest corridors, invigorated steppe in leeward interiors, and heightened reliance on littoral and riverine proteins.

• Early Holocene (post-11.7 ka): Monsoons strengthened; Amazonian gallery forests re-expanded and linked; Andean snowlines retreated; estuaries and lagoons from Marajó to Santa Catarina and along Peru–Atacamastabilized as sea level rose toward modern positions.

Subsistence & Settlement

By ~13–12 ka, humans were widely established from Pacific Peru to the Andean forelands and major lowland trunks; settlement was semi-recurrent and water-anchored, with strong coastal–river–valley coupling:

• Pacific littoral (Peru–N. Chile): Coves within the Humboldt Current hosted intensive harvest of shellfish, rockfish, anchoveta, sea lions, seabirds, and seaweeds, likely via raft/dugout logistics along a proto “kelp highway.” Shell scatters and strandline hearths signal repeated use of the same landings.

• Andean valleys & puna: Rock-shelter and terrace hamlets targeted deer, vicuña/guanaco, vizcacha and caviomorph rodents, and wild tubers; riparian stands (e.g., chenopods, amaranths) were increasingly curated and processed on grindstones. Seasonal rounds linked high-puna hunts to valley springs and alluvial plots.

• Amazon–Orinoco lowlands & Guianas: Wet-season camps on natural levees exploited fish, turtles, caimans, capybara, and abundant palm fruits; varzea/igapó mosaics encouraged orchard-garden tending around hamlets. On the Guianas Shield, foragers navigated inselberg–savanna–gallery forest patchworks with broad-spectrum diets.

• Atlantic Brazil strandplains: A still-wide coastal plain nurtured early shell-midden nuclei at estuary mouths and dune-lagoon fringes, where bivalves, crustaceans, finfish, and marine mammal remains attest to repeated feasting and aggregation.

• South America Minor (Patagonia–Fuegia): Along the fjord and channel coasts, foragers exploited kelp-forest seams (mollusks, fish, sea mammals) and likely staged short canoe/raft crossings; east of the Andes, steppe camps organized around guanaco drives, rhea hunts, and lake-margin waterfowl.

Across the continent, communities tethered to refugial nodes—springs, levees, coves, and rock shelters—while maintaining seasonal mobility across adjacent ecozones.

Technology & Material Culture

Toolkits balanced expedient mobility with targeted specialization:

• Lithics: pervasive microlithic flake–blade industries; backed bladelets, scrapers, burins; regional obsidian/siliceous networks in Andean forelands and Patagonian steppes.

• Aquatic gear: bone gorges and harpoons, composite points, net floats/sinkers; stake-weirs and basket traps emergent on salmon-bearing and whitefish rivers by late in the period.

• Processing tools: grindstones/querns in Andean and lowland contexts for seeds, tubers, and pigment; shell adzes in littoral zones.

• Containers & clothing: organic carriers (gourds, bark, skin), early netting and twined bags; tailored hides; ochre for body/ritual use; shell/seed/teeth ornaments in burials and feast contexts.

Movement & Interaction Corridors

Deglaciation and rising seas reconfigured, but did not diminish, connectivity:

• Pacific kelp-forest corridor: cove-to-cove and island-to-island movements along Peru–N. Chile’s productive littoral.

• Andean valley strings: rock-shelter nodes at springs and passes (Cochabamba, Puna de Atacama, Cuzco–Titicaca arc) linked high–mid–low altitude resource zones.

• Amazon–Orinoco trunks: Solimões–Madeira–Xingu–Tapajós–Negro–Orinoco served as driftways and portage chains, coupling previously isolated forest refugia.

• Atlantic strandlines: broad Brazilian shore supported early along-shore movement between lagoon fisheries and stone/palm resources inland.

These braided pathways moved dried fish and meats, palm starch/oils, lithics, pigments, and stories, re-knitting the continent after the LGM.

Cultural & Symbolic Expressions

Water and stone framed early ritual landscapes:

• Rock shelters in Andean and foreland belts preserved hearths, pigment floors, and engraved/painted panels, marking places of teaching, exchange, and ceremony.

• Shell-mounds on Pacific and Atlantic coasts functioned as feast and ancestor markers, accumulating over generations at favored landings.

• Ochred burials and personal adornments (shell/seed/teeth beads) bespeak lineage memory and emerging territoriality, often at river mouths, levees, and springs.

Environmental Adaptation & Resilience

Resilience rested on refugia-tethered, multi-sited portfolios:

• Refugium anchoring (lagoons, levees, springs) ensured dependable access to water and food as climate oscillated.

• Broad-spectrum diets—littoral proteins paired with riparian and forest fare—buffered interannual variability, especially through the Younger Dryas cool/dry interval.

• Seasonal scheduling across coast–valley–puna and river–terra firme–floodplain gradients spread risk; early orchard/patch management around camps enhanced reliability.

• Storage of smoked fish and meat, roasted seeds/tubers, and rendered oils sustained longer stays and supported semisedentism.

Long-Term Significance

By 7,822 BCE, deglaciated Andean valleys, re-connected Amazon–Orinoco forests, and stabilizing littorals sustained semi-recurrent camp landscapes and nascent shell-midden nodes.
In the south-cone, dual kelp-edge and steppe economies were firmly in place, poised for the canoe-borne traditions of the Fuegian channels.
Across South America, the operating code of the coming Holocene was already legible: water-anchored, broad-spectrum subsistence; mobility braided to refugial anchoring; early plant tending; food storage; and ritualized claims to the enduring places that made life secure.

South America Major (28,577–7,822 BCE) | Upper Pleistocene II: Deglaciation, Refugia Reconnection, and Littoral Gateways

South America Major includes all regions north of the Río Negro: Colombia (except Darién), Venezuela, the Guianas, Brazil, Ecuador (excluding the Ecuadorian Capelands, which belong to Isthmian America), Peru, Bolivia, Paraguay, Uruguay, northern Argentina, and northern Chile.

Anchors: the Northern Andes (Quito–Cuzco–Titicaca–Altiplano), Amazon Basin (Solimões–Madeira–Xingu–Tapajós–Marajó), Orinoco–Llanos, the Atlantic Brazil shelf/coast (including sambaqui coasts), the Guianas Shield, and Atacama oases and salars (northern Chile).

• Andean glaciers receded from late LGM maxima; puna and páramo belts rose upslope.

• Amazon/Guianas: fragmented rainforest refugia reconnected along major trunks (Solimões, Madeira, Xingu, Tapajós).

• Pacific littoral (Peru/ N. Chile): upwelling zones built shell- and kelp-rich coves; Atlantic Brazil shelf still broader than today.

• Orinoco–Llanos: wetlands and gallery forests expanded in interstadials.

Climate & Environmental Shifts

• Bølling–Allerød (14.7–12.9 ka): warmer/ wetter pulses reforested lowlands and stabilized Andean valley hydrology.

• Younger Dryas (12.9–11.7 ka): cool/dry reversal; forest corridors pinched; littoral protein became critical.

• Early Holocene (after 11.7 ka): warmth returned; rainfall increased, rivers bloomed.

Subsistence & Settlement

• Secure, widespread human presence by ~13–12 ka across Pacific Peru, Andean foothills, and riverine lowlands:

  • Pacific coves (Peru/N. Chile): intensive shellfish, fish, seabirds; strandings; sea-plant harvesting (kelp, algae).

  • Andean valleys: deer, camelids (vicuña/guanaco in high puna), rodents, wild tubers; riparian plants.

  • Amazon/Orinoco: fish, turtles, capybara; palm fruits; small-game; wet-season camps on natural levees.

• Guianas Shield: mixed forest-savanna foraging on inselbergs and gallery forests.

Technology & Material Culture

• Microlithic flake–blade industries; bone gorges/harpoons; shell adzes in littoral zones; grindstones in Andean/lowland seed processing.

• Ochre for body/ritual use; shell/seed ornaments.

Movement & Interaction Corridors

• Pacific coastal “kelp highway”: cove-to-cove canoe/raft mobility;

• Andean valley strings: springs/rock-shelter chains;

• Amazon–Orinoco trunks + levee ridges: seasonal canoe drift and portage;

• Atlantic Brazil strandlines: early shell-midden nuclei.

Cultural & Symbolic Expressions

• Early rock-shelter ritual spaces in Andean/foothill belts; structured hearths; ochred burials.

• Coastal shell-mounds served as feast/ancestor markers.

Environmental Adaptation & Resilience

• Refugium tethering (riverine, littoral, and valley springs) + broad-spectrum diets reduced risk; seasonal scheduling across ecozones buffered the Younger Dryas.

Transition

By 7,822 BCE, deglaciated valleys, reconnected forests, and productive coasts supported semi-recurrent landscapes of camps and shell-midden nodes, setting the stage for semi-sedentary Holocene economies.

South America Minor (28,577–7,822 BCE) | Upper Pleistocene II: Deglaciation, Kelp-Edge Shores, and Steppe Gateways

Geographic & Environmental Context

South America Minor includes southern Chile (incl. Central Valley), southern Argentina (Patagonia south of the Río Negro/Río Grande), Tierra del Fuego, Falkland/Malvinas, Juan Fernández.

Anchors: Patagonian steppe, Andean icefields, Strait of Magellan–Beagle Channel, Fuegian archipelago, Pacific fjords, Atlantic shelf banks.

• Cordilleran icefields retreated, carving deep fjords along southern Chile; proglacial lakes dotted the eastern steppe.

• Atlantic shelves broadened; coastal banks enriched fisheries.

• Strait of Magellan–Beagle shores gained new landing coves.

Climate & Environmental Shifts

• Bølling–Allerød warming opened grasslands and woodlands; Younger Dryas reintroduced cold/dry steppe; strong westerlies persisted.

Subsistence & Settlement

• Human presence in the wider south-cone by >14.5 ka (e.g., Monte Verde just north of this subregion) expanded into our zone:

  • Pacific fjords/kelp coasts: shellfish, fish, sea lions, seabirds; shore whaling/scavenging; seaweeds.

  • Patagonian steppe: guanaco hunts; rhea; small game; waterfowl at lakes.

  • Magellan–Beagle: fortified coves used for seasonal aggregation; strand-midden nuclei formed.

Technology & Material Culture

• Flake–blade microlithic industries; bone/antler points; fish gorges; harpoons; hide scrapers; fire-hearths/ovens in coves.

• Early raft/canoe craft (probable) for short crossings.

Movement & Interaction Corridors

• Kelp highway along Pacific; fjord/archipelago stepping-stones to Fuegian realm.

• Steppe: spring–lake circuits; Andean passes to leeward zones.

Cultural & Symbolic Expressions

• Rock-shelter paints/engravings in steppe margins; shell-midden feasting signatures.

Environmental Adaptation & Resilience

• Dual coastal–steppe scheduling hedged against cold pulses and resource crashes; storability (smoked meat/fish) prolonged residency.

Transition

By 7,822 BCE, southern cone foragers had staked coast–steppe dual economies, poised for canoe lifeways in Fuegian channels.

The Ends of the Earth, one twelfth of the Earth’s surface, is bordered by the South Atlantic and South Pacific Oceans and includes Subcontinental South America, the Chonos Archipelago, Chiloé Island, Tierra del Fuego, the Falkland Islands, the remote Juan Fernández Islands (notably home to the marooned sailor Alexander Selkirk from 1704 to 1709, an experience thought to have inspired Daniel Defoe’s Robinson Crusoe), the even more remote Easter Island, and West Antarctica—the portion of Antarctica that lies within the Western Hemisphere and includes the Antarctic Peninsula.

Easter Island, culturally Polynesian yet governed by Chile, is among the most isolated inhabited islands in the world, positioned in the eastern South Pacific Ocean at the northwestern edge of The Ends of the Earth, along with the equally remote Pitcairn Islands.

The southeastern and southwestern boundaries divide West Antarctica from the much larger East Antarctica.

The northeastern boundary follows the approximate courses of the Colorado and Barrancas Rivers, which flow from the Andes to the Atlantic Ocean and are traditionally recognized as the northern limit of Argentine Patagonia.

For Chilean Patagonia, most geographers and historians identify its northern boundary at the Huincul Fault in the Araucanía Region.
