The Cataclysm Cycle carries the broader account of recurrence. Randall Carlson connects catastrophic flood evidence with sacred proportions and the knowledge those proportions preserve. His work asks how geology and ancient measurement together disclose the timing of a civilizational reset.
Biographical Context and the Dual Vocation
Randall Carlson is an American independent researcher, master builder, and lecturer. His work joins geomorphology, the study of how landscapes acquire their form, with archaeoastronomy, the study of astronomy in ancient cultures. Sacred geometry connects both pursuits to architecture and cosmological order. His training as a designer and builder gives the inquiry a practical basis.
Carlson approaches monuments with experience of how people construct large structures. He approaches landscapes through field observation of the physical processes that shape them. These skills join craft knowledge to independent scholarship. Schwaller de Lubicz and Keith Critchlow belong to the same intellectual lineage. For them, sacred architecture and cosmological order formed one subject of inquiry.
Collaboration with Graham Hancock helped bring Carlson’s catastrophist research to a wider public. Appearances on the Joe Rogan Experience from the mid-2010s gave decades of fieldwork a large audience. Academic resistance to catastrophist hypotheses had kept much of that audience from the material. The collaboration increased public interest in the Younger Dryas impact hypothesis. It also raised the question of whether conventional accounts of civilization’s beginnings fit the evidence.
The Scablands and the Evidence of Catastrophic Flooding
The Channeled Scablands of eastern Washington supply Carlson’s foundational field evidence. Stripped basalt covers a landscape of giant current ripples, with hundreds of feet between crests. Massive gravel bars stand at elevations that ordinary river flows cannot explain. Drainage channels cut hundreds of feet into solid rock. These forms preserve the action of water on a scale beyond familiar floods.
J Harlen Bretz proposed catastrophic flooding as their cause in the 1920s. He argued that floodwaters of unprecedented magnitude had carved the landscape within days or weeks. The geological establishment rejected his thesis for more than four decades. Its objection rested on uniformitarianism, the discipline’s commitment since Lyell to explaining past landscapes through ordinary processes. Bretz’s floods demanded a scale those interpretations refused to admit.
Accumulating evidence eventually secured acceptance of the catastrophic explanation. Bretz received the Penrose Medal in 1979 at ninety-six. His vindication established the Scablands as a record of rapid, immense physical change.
Carlson continued mapping that record and documenting separate flood events. The landscape preserves a series of enormous outbursts. Ice dams repeatedly failed around glacial Lake Missoula. Each collapse released water estimated in the hundreds of cubic kilometers within days. Successive releases together shaped the channels, deposits, and stripped surfaces that Bretz described.
This local evidence grounds the broader catastrophist question. The recent geological past includes events larger than anything observed during the instrumental era. Those floods also exceed the scale that gradualist interpretations admitted as normal. Their established occurrence changes how other anomalies can be examined. The next question concerns comparable events elsewhere and the traces they left in successive geological layers.
The Younger Dryas Boundary and the Impact Hypothesis
Carlson became a leading independent popularizer of the Younger Dryas impact hypothesis developed by Firestone, West, Kennett, and their collaborators. His synthesis brings their peer-reviewed geochemical evidence together with the flooding he documented. Boundary markers include nanodiamonds, microspherules, platinum-group metals, and magnetic spherules. Graham Hancock and other researchers supplied the archaeological and mythological part of the synthesis.
The proposed event combines several processes within a compressed interval approximately 12,800 years before the present. A comet fragmented and produced airbursts over the North American ice sheet. Rapid melting then drove catastrophic floods alongside sudden climate reversal and the extinction of most North American megafauna. This sequence links the distributed markers to the violence preserved in the landscape.
Researchers have reported multiple boundary markers and flood signatures across sites since the original 2007 paper. Three causal questions remain disputed: the initiating object, the chain connecting its effects, and its contribution to extinction and climate forcing. A growing record has enlarged the inquiry without closing those questions.
Carlson’s judgment is that the impact hypothesis has passed the threshold of reasonable doubt. He identifies part of the remaining resistance as institutional. That conclusion belongs to his synthesis. The distinction between his judgment and the unresolved causal questions preserves what the evidence and its interpretation each contribute.
Sacred Geometry and the Cosmological Architecture
Carlson’s sacred-geometric research runs beside his geology. Schwaller de Lubicz‘s work at Luxor supplies one foundation. John Michell, Keith Critchlow, and Robert Lawlor supply others. Carlson examines monumental proportions from Göbekli Tepe through the Egyptian pyramids to Gothic cathedrals. He identifies recurring canonical proportions across cultures and epochs.
For Carlson, that recurrence points to a shared intellectual tradition. Independent invention fails to account for the pattern he identifies. The proportions draw on the harmonic series, ratios between planetary orbital periods, and the geometry of the Earth–Moon–Sun system. Together, they join astronomy, mathematics, and architectural proportion into a coherent body of knowledge.
Carlson places the origin of that knowledge substantially before the conventional beginning of civilization. On his account, Göbekli Tepe’s builders inherited a tradition already old when they built the site. The tradition survived the Younger Dryas catastrophe. Mystery schools carried it into the historical period. This is his proposed transmission of an integrated system of cosmic measure.
Stone and ritual preserve that system through conditions that destroy written records. Libraries burn, and populations scatter. Proportions remain embodied in monuments, while ritual use preserves how people engage and interpret those forms. Successor civilizations learn to read the stones, recover the knowledge, and extend its practice. Carlson identifies Egyptian, Mesoamerican, and Gothic traditions as descendants of such recovery.
Sacred geometry therefore supplies a means of continuity across the reset. Cosmic order enters architectural form and ritual practice. Those forms return knowledge to people who inherit them after catastrophe. The monument carries a relation that its later readers can make active again.
The Precessional Clock and the Timing Question
Carlson connects field geology and sacred geometry through a hypothesis about catastrophe timing. He places the idealized 25,920-year Great Year beside proposed changes in cosmic-ray exposure, debris-stream encounters, and geological evidence. Axial precession describes the changing orientation of Earth’s rotation axis. It does not carry the solar system through the galactic plane or change Earth’s orbit through a meteoroid stream. Those hazards have their own orbital variables and periods.
A causal account must identify the physical forcing that shares the proposed phase. It must also establish that relation’s stability through time. Predictions then need testing against impact or climate evidence withheld from the original fit. A numerical correspondence alone leaves those causal requirements unmet.
Carlson reads ancient precessional measurement as knowledge of recurrence. Ancient astronomers tracked the clock because they understood its connection to catastrophe. Calendar, temple, and pyramid measured the cycle and preserved that measurement through transitions. Their proportions gave the inherited knowledge a durable physical form.
Santillana and von Dechend’s Hamlet’s Mill supplies the scholarly basis for reading myth as encoded precessional knowledge. Carlson extends that account toward particular geological events and architectural proportions. Narrative, monument, and landscape together carry his reconstruction of the cycle.
Within this timing account, the present precessional position helps estimate proximity to the next window. Carlson has declined to commit to particular dates as some catastrophist researchers do. His argument nevertheless places the current generation within a period of risk above the long-term average. Preparedness and recovery of ancient knowledge become practical responses to that recurrence.
