Randall returns: Texas field plans, caves, and rapid-formed flood landscapes
Joe welcomes Randall Carlson back and they start with logistics: a 1,000-mile winter drive and planned site visits in Texas. Randall explains Halls Cave (megafauna, Clovis tools, and the Younger Dryas “black mat” layer) and then contrasts it with Canyon Lake Gorge, a modern flood-cut landscape formed in days.
- •Halls Cave as a stratified record: megafauna below, black mat layer, fewer remains above
- •Black mat layer described as soot/charcoal tied to widespread fires
- •COVID-era access restrictions delaying cave exploration
- •Canyon Lake Gorge as a real-world demonstration of rapid cataract/plunge-pool formation
- •Challenge to slow, uniformitarian assumptions when similar features form in days
- 3:24 – 7:21
Younger Dryas refresher: abrupt climate reversal, ice sheets, and the Clovis disruption
Joe asks for a quick recap of the Younger Dryas impact theory and its implications for extinctions and “reset” events. Randall lays out the Late Glacial Maximum context, the warming trend, then the sudden 12,850-year cold snap lasting ~1,300 years and its correlation with extinctions and the disappearance of the Clovis culture.
- •Late Glacial Maximum ice extent (Laurentide/Cordilleran ice sheets)
- •Milankovitch cycles as background driver of long-term warming/cooling
- •Abrupt onset of Younger Dryas around ~12,850–12,900 years ago
- •Mass extinctions and cultural disruption at the boundary (Clovis disappears)
- •Younger Dryas ends ~11,600 years ago, transitioning into the Holocene
- 7:21 – 14:40
Meltwater pulses and the ‘energy paradox’: why did the ice melt so fast?
Randall connects the Younger Dryas bookends to major meltwater pulses (1A and 1B) and rapid sea-level rise. He introduces the ‘energy paradox’ identified in the 1970s: known heat sources and gradual models don’t provide enough energy to melt ice sheets at the observed rates—especially if melting occurred in pulses rather than smoothly.
- •Meltwater Pulse 1A (~14,600 years ago) and 1B (~11,600 years ago) as major sea-level events
- •Holocene boundary defined at ~11,600 years ago; civilization accelerates afterward
- •Radiocarbon dating forced revisions: deglaciation faster than older models
- •Conferences in the 1970s highlight unresolved ‘energy paradox’
- •Pulsed melting implies even larger, concentrated energy inputs than gradual melt
- 14:40 – 17:31
Impact proxies and evidence: melt glass, microspherules, nanodiamonds, and platinum spikes
Joe asks about ‘trinitite’ and impact glass as a clue in core samples. Randall outlines multiple impact proxies used in the Younger Dryas debate and explains how high-velocity impacts vaporize material, distribute it globally, and leave distinct chemical/mineral signatures.
- •Melt glass (trinitite-like material) as one impact proxy
- •Microspherules and microtektites formed from vaporized/condensed ejecta
- •Nanodiamonds requiring extreme heat/pressure conditions
- •Platinum-group metal spikes (iridium, osmium, platinum) in ice cores/sediments
- •Charcoal/soot layers consistent with widespread fires and the black mat
- 17:31 – 26:53
Debate dynamics: critics, growing research teams, and why catastrophes face resistance
Randall describes the initial backlash to the 2007 Younger Dryas impact paper and notes the expansion of the Comet Research Team over time. He and Joe discuss how impact explanations ‘tie together’ multiple anomalies, while institutional incentives and existing paradigms can slow acceptance.
- •2007 paper’s reception: heavy criticism despite multi-author backing
- •Comet Research Team growth (from ~17 to 50+ members)
- •Example of a skeptic converting after field evidence review (Chris Moore)
- •Impact hypothesis as a unifying explanation for rapid changes
- •Broader discussion of why disruptive hypotheses meet resistance
- 26:53 – 32:53
Multiple impacts, comet streams, and Plato’s ‘Phaeton’ as a catastrophe memory
The conversation shifts from single-impact framing to impact epochs: clustered events, meteor streams, and periodic increased risk. Randall links this to Plato’s framing of Atlantis via the Phaeton myth, arguing that ‘myths’ may preserve real observations of cosmic catastrophes and sea-level rise timing that intriguingly matches ~11,600 years ago.
- •Randall’s estimate: possibly ~10 impacts, concentrated near Younger Dryas onset
- •Meteor streams as ‘danger intersections’ with dense pockets of debris
- •Plato’s Atlantis chronology aligning with ~11,600 years ago (Meltwater Pulse 1B)
- •Phaeton story interpreted as a ‘myth with a real referent’ (heavenly bodies causing fires)
- •Geomythology: myths as encoded records of real geological/cosmic events
- 32:53 – 51:18
Richat Structure and Atlantis candidates: volcanic geology, alignments, and the Azores Plateau case
Joe asks about the Richat Structure’s concentric rings; Randall argues it’s natural (volcanic doming/truncation) while noting nearby impact craters and an interesting alignment. He then outlines why he considers the sunken Azores Plateau the best match to many of Plato’s geographic details, focusing on isostasy, vertical crustal motion, and evidence for recent subsidence.
- •Richat Structure explained as volcanic uplift/doming with erosion exposing rings
- •Nearby impact craters in Mauritania and a debated alignment coincidence
- •Azores Plateau positioned at a triple-plate junction on the Mid-Atlantic Ridge
- •Isostasy: land rebound after ice unload; ocean basins/ridges respond to added water mass
- •Dredged shallow-water fossils/limestones suggesting former islands above sea level ~12k years ago
- 51:18 – 58:47
Could there be evidence underwater? Submersible archaeology, tsunamis, and what would ‘prove’ it
Joe presses on what physical evidence would confirm settlement (pottery, infrastructure). Randall notes the plateau is largely a mile-plus underwater and argues that only serious underwater exploration could settle the question, while also emphasizing how catastrophic sea-level rise and seismicity could erase or bury traces.
- •Depth challenge: much of the Azores Plateau lies ~1–1.5 miles underwater
- •Plant remains and shallow-water indicators vs. lack of confirmed human artifacts
- •Submersible/underwater archaeology as the next step
- •Massive tsunamis and seismic events as plausible destruction mechanisms
- •What to look for: artificial ring-like infrastructure or unmistakable cultural debris
- 58:47 – 1:21:09
Near-Earth threats: asteroids, the Taurid stream, Tunguska, and the ‘cosmic blind spot’
Randall pivots to modern impact risk and shows a long compilation of near-miss headlines since the late 1980s. He explains why some objects are hard to detect (approaching from the Sun’s direction), argues Tunguska likely relates to the Taurid meteor stream (Comet Encke debris), and emphasizes how frequently significant objects pass close to Earth.
- •Close-encounter headline chronology illustrating frequent near misses
- •Tunguska as an airburst flattening forests; likely Taurid-stream related
- •Earth crosses the Taurid stream twice yearly; one crossing is hard to observe (sunward)
- •Discovery rates rising sharply with improved surveys (near-Earth asteroid chart)
- •Realization that near-Earth space is far more crowded than once assumed
- 1:21:09 – 1:46:54
Planetary defense: DART, lead time, and a Space Force connection
Joe asks how prepared humanity is to deflect large objects; Randall’s answer is essentially ‘not yet,’ with civilization dangerously dependent on fragile supply chains. They discuss the logic of early detection and small course corrections, then Randall recounts being contacted by former Space Force leader Matt Lohmeier about presenting on planetary defense—an effort derailed by COVID and Lohmeier’s dismissal after criticizing ‘wokeism’ in the military.
- •Deflection feasibility depends on early detection and incremental ‘nudges’
- •DART mission concept: testing kinetic impact/attached boosters to alter trajectory
- •Supply-chain fragility and limited global food buffer (~months)
- •Matt Lohmeier outreach to Randall about briefing base commanders on planetary defense
- •Side discussion: military politics and how institutional priorities shape preparedness
- 1:46:54 – 2:16:36
Catastrophic flood evidence: Channeled Scablands, coulees, Dry Falls, and rapid erosion mechanics
Using Google Maps and drone footage, Randall walks Joe through eastern Washington’s Channeled Scablands—areas stripped of loess to expose basalt by enormous meltwater floods. He explains coulees, terminal moraines, recessional cataracts, and ‘kolking’ (turbulent drilling) that can carve bedrock features quickly, while debating whether conventional Lake Missoula outburst-flood models fully explain the scale and frequency.
- •Scablands: soil stripped to basalt, revealing flood pathways and erosional scars
- •Coulees (e.g., Moses Coulee/Grand Coulee) carved rapidly by immense discharges
- •Dry Falls and Potholes Cataract as ‘fossil Niagara’-scale cataracts
- •Kolking turbulence drilling potholes/plunge pools into bedrock
- •Randall’s hypothesis of multiple catastrophic flood episodes (~14,600, ~12,850, ~11,600 years ago)
- 2:16:36 – 3:05:45
From geology to society: cooling vs warming risks, solar storms, education, and building resilient thinking
The discussion broadens from impacts to other existential risks: volcanic winters, solar variability, Carrington-type events, and how cooling often drives famine and collapse. They end on cultural themes—scientific dogma, institutional incentives, social-media distraction, and Randall’s plans for an alternative education platform (HowTube) plus a physical institute emphasizing hands-on learning and real-world skills.
- •Cooling events as historically more destabilizing than warming (crop failures, famine, disease)
- •Sun variability and solar storms (Carrington Event; larger events inferred from tree rings)
- •Scientific/academic resistance to paradigm shifts (catastrophism, ancient timelines)
- •Vulnerability of modern infrastructure and communications to solar/space weather
- •Randall’s HowTube + institute concept: hands-on, applied math/science education
