Africa, Eurasia, Island Southeast Asia, and Oceania; ancient contact zones remain only partly resolved · ~60,000 – 40,000 BCE · Hominin Evolution
Ancient and modern genomes show that modern humans interbred with Neanderthals and Denisovan-related populations, while Neanderthals and Denisovans also had children together. Most living populations outside Africa carry roughly 1–3 percent Neanderthal ancestry, although estimates vary. Denisovan ancestry is distributed more unevenly and is highest in parts of Oceania and Island Southeast Asia. The evidence revises a strict replacement-only version of Out of Africa into a model of predominantly recent African origins with limited archaic admixture.

Earth; some variants extend the search to the Moon or Mars · Speculative – pre-human deep past · Hominin Evolution
The strongest version asks what geological traces an industrial society might leave after millions of years. It does not report a discovery. No accepted pre-human artifact assemblage, industrial stratum, city, mine, synthetic residue, writing system, or biological maker currently demonstrates such a civilization.

Gobustan (Qobustan), approximately 60–70 km southwest of Baku, Azerbaijan · ~40,000 – 5,000 BCE · Paleolithic Period
More than 6,000 engravings, together with caves, settlements, and burials, document repeated use of Gobustan from deep prehistory into historical periods. Boats, animals, human figures, hunting, fishing, and group scenes are genuine motifs, but they do not by themselves prove migration to Scandinavia or a lost maritime civilization.

Chinchihuapi Creek wetland near Puerto Montt, Los Lagos Region, southern Chile · ~14,500 BCE · Paleolithic Period
The classic Monte Verde II interpretation combines dated organic remains, wooden features, hearths, plants, stone artifacts, and other contextual evidence for a late Pleistocene hunter-gatherer occupation in southern Chile. Older activity claims are less secure, and a 2026 paper has reopened debate over the age and formation of the best-known level.

Northeast Siberia, Alaska, Yukon, and the now-submerged continental shelf beneath the Bering and Chukchi seas · ~20,000 – 11,000 BCE · Paleolithic Period
Geology establishes repeated land exposure, paleoecology reconstructs habitable environments, and ancient DNA strongly connects the ancestry of Indigenous peoples of the Americas with populations rooted in northeast Asia and Beringia. The main uncertainties concern timing, population structure, and routes south of the continental ice sheets.

Global paleoclimate records, with especially important evidence from Greenland ice cores, North Atlantic records, North American archaeological and sedimentary sites, European records, and selected Near Eastern sites. · ~12,900 BCE · Younger Dryas Impact Hypothesis
The Younger Dryas Boundary marks the transition into the Younger Dryas cold interval, an abrupt return to colder conditions near the end of the last Ice Age. In climate science, the Younger Dryas itself is real and well documented in Greenland ice cores, lake sediments, marine records, pollen, and other paleoclimate archives. The disputed claim is that reported markers at geographically separated sites near the Younger Dryas onset define a synchronous impact horizon. Do not describe a globally recognizable impact layer as an established object; marker identity, age, synchrony, and diagnostic value remain contested.

Best known from western North American archaeological and spring/wetland settings, with broader YDIH claims extending the idea to sites on multiple continents. · ~12,900 BCE · Younger Dryas Impact Hypothesis
The black mat is real. It is not one single worldwide ash layer. In the strict geoarchaeological sense, it refers to organic-rich wetland soils, marsh deposits, diatomites, peats, and similar dark or gray-white deposits that formed around springs, wetlands, pond margins, and valley bottoms during the late Pleistocene to early Holocene transition. C. Vance Haynes popularized the term in discussions of Clovis sites and noted that these deposits often overlie the last clear traces of terminal Pleistocene megafauna and Clovis-era activity. That made the black mat important before the impact theory became popular.

Inner Solar System debris stream intersecting Earth orbit. Apparent radiant near Taurus for nighttime Taurids; related daytime showers are observed by radar/radio methods. · Recurring astronomical cycle · Younger Dryas Impact Hypothesis
The Taurid Meteor Stream is real. Earth crosses debris associated with the Taurid Complex, producing the Northern and Southern Taurid meteor showers in the fall and related daytime showers such as the Beta Taurids around late June. These showers are associated mainly with Comet 2P/Encke and possibly related near-Earth objects. The Taurids are notable because they are broad, long-lasting, and known for occasional bright fireballs. Modern meteor research also supports the existence of resonant branches or swarms with larger meteoroids. That makes the Taurid Complex scientifically interesting for meteor astronomy and planetary-defense studies.

Atlantic Coastal Plain of the southeastern United States, with strongest public association in North Carolina and South Carolina. · ~12,900 BCE (proposed) · Younger Dryas Impact Hypothesis
Carolina Bays are thousands of elliptical depressions, wetlands, ponds, and shallow lakes scattered across the Atlantic Coastal Plain, especially in the Carolinas and nearby states. They are real landforms, and some preserve useful ecological and environmental records. Current terrestrial interpretations treat Carolina Bays as relict coastal-plain landforms with basin-specific, potentially multi-stage histories. Eolian reworking and lake-margin processes are documented in regional studies, but no single mechanism should be presented as a settled explanation for every bay.

Global mean sea-level episode reconstructed from regionally different records · ~14,600 – 14,300 BCE · Younger Dryas Impact Hypothesis
Dated corals, drowned reefs, sea-level indicators, and geophysical models support a major rise near the Bølling warming, commonly estimated at roughly 14 to 20 metres over several centuries.

Norwegian continental margin, with tsunami effects around the North Atlantic basin. · ~6,100 BCE · Younger Dryas Impact Hypothesis
The Storegga Slide was a massive submarine landslide on the Norwegian continental margin. Around 8150 to 8200 years ago, part of the seafloor failed and generated a tsunami that affected coastlines around the North Atlantic, including Norway, Shetland, mainland Scotland, the Faroe Islands, and possibly parts of Greenland and Denmark. The landslide and tsunami are strongly supported by seafloor mapping, sediment cores, tsunami sand layers, radiocarbon dating, and numerical modeling. The public story often connects Storegga to Doggerland, the now-submerged Mesolithic landscape in the southern North Sea. That connection is real, but it is often overstated. Storegga likely caused dangerous regional inundation in some coastal zones, but Doggerland was already shrinking because of postglacial sea-level rise. Current modeling suggests the tsunami was not necessarily the single cause of Doggerland abandonment or final submergence.

Mediterranean basin, Strait of Gibraltar, Alboran Sea, Sicily Channel, and eastern Mediterranean pathways. · ~5.3 million BCE · Younger Dryas Impact Hypothesis
The Zanclean Flood is the hypothesis that Atlantic water catastrophically refilled the Mediterranean basin after the Messinian Salinity Crisis, when restricted connections to the Atlantic caused extreme salinity changes and large evaporite deposits across the Mediterranean. The most cited version argues that the final refilling happened around 5.33 million years ago through the Gibraltar gateway, with peak discharge far larger than any modern river. The strongest modern version comes from Garcia-Castellanos and colleagues, who argued that erosion at Gibraltar could have produced a feedback loop: more water cut the channel deeper, which let more water in, which caused even more erosion. Their model suggested that most of the final refill may have happened within months to two years. Later work in the eastern Mediterranean and Sicily added possible evidence for megaflood deposits and erosion pathways.

Glacial Lake Missoula in western Montana, an ice-dam area near northern Idaho, flood pathways across Idaho and eastern Washington, and the Columbia River system through Oregon and Washington. · ~15,000 – 13,000 BCE · Younger Dryas Impact Hypothesis
The Missoula Floods were enormous late Ice Age floods produced when the Cordilleran Ice Sheet blocked the Clark Fork drainage near northern Idaho and created Glacial Lake Missoula in western Montana. When the ice dam failed, water rushed westward across Idaho, eastern Washington, the Columbia Gorge, and into the Pacific drainage system. These floods carved and modified the Channeled Scabland, deposited huge gravel bars, moved erratic boulders, formed giant current ripples, and left slackwater deposits in temporary flood lakes. The floods are one of the clearest cases where a catastrophic geological interpretation, first strongly advanced by J Harlen Bretz in the 1920s, was resisted, tested, refined, and eventually accepted. Later work by Joseph Pardee, Victor Baker, Richard Waitt, Brian Atwater, John Clague, Jim O'Connor, and others helped turn the floods from a controversial interpretation into a mainstream geologic model.

Southwest Indian Ocean, generally described as east of Madagascar and west of Australia. · ~2800 BCE (proposed) · Younger Dryas Impact Hypothesis
The Burckle Crater Claim was promoted by members of the Holocene Impact Working Group in the 2000s. The proposed crater is described as an undersea feature roughly 29 kilometers across in the southwest Indian Ocean. Proponents argued that large coastal chevron dunes in places such as Madagascar and Australia could point back toward an ocean impact that generated an enormous tsunami. The claim is not accepted as a confirmed impact crater. The evidence is indirect: bathymetric shape, proposed tsunami-direction logic, coastal chevrons, and claimed unusual particles or deposits. Strong confirmation of an impact crater normally requires diagnostic evidence such as shocked minerals, shatter cones, impact melt, geochemical anomaly, breccia, drilling cores, or a clear geophysical structure. Those standards have not been met publicly for Burckle.

Southeast Pacific or Southern Ocean region, near the Bellingshausen Sea and roughly 1,500 km southwest of Chile. · ~2.5 million BCE · Younger Dryas Impact Hypothesis
The Eltanin impact occurred about 2.51 million years ago in the Gelasian, earliest Pleistocene under the current International Chronostratigraphic Chart; older papers call it late Pliocene because they used the former boundary. Sediment cores preserve noble-metal enrichment, meteoritic material, glassy spherules, and disturbed marine layers. Its importance for this map is mostly comparative. It shows that a sizable asteroid or bolide impact into deep ocean is geologically possible and can leave evidence without an obvious crater. It does not explain the Younger Dryas, post-Ice-Age flood traditions, or human civilization-reset stories because it occurred roughly 2.5 million years ago, far before the relevant human cultural period.

Public claim network centered largely in North American catastrophe geology, especially the Channeled Scablands / Missoula Floods, but extended into global myth, astronomy, and ancient-knowledge claims. · ~12,900 – 6,000 BCE (focus) · Younger Dryas Impact Hypothesis
Randall Carlson is a prominent public popularizer of modern catastrophism in alternative-history media. Carlson is important to the map because he functions as a bridge between mainstream-recognized catastrophic geology and more speculative internet claim networks. His discussions of the Missoula Floods, Channeled Scablands, Younger Dryas Impact Hypothesis, Taurid Meteor Stream, flood myths, sacred geometry, and ancient knowledge have shaped how many online audiences understand late Ice Age catastrophe.
