Randall Carlson

Biographical Context and the Dual Vocation

Randall Carlson is an American independent researcher, master builder, and lecturer whose work spans geomorphology, archaeoastronomy, and the tradition of sacred geometry as applied to architecture and cosmology. He trained as a designer and builder, operating within the craft traditions of architectural and monumental construction, and brings to his geological and cosmological work the practitioner’s eye for how large structures are actually built and how landscapes are actually shaped by physical processes. This combination of craft knowledge, field observation, and independent scholarship places him in a lineage that includes figures like Schwaller de Lubicz and Keith Critchlow, for whom the study of sacred architecture and the study of cosmological order were indivisible pursuits.

Carlson’s emergence as a public figure in catastrophist research owes substantially to his collaboration with Graham Hancock and his appearances on the Joe Rogan Experience podcast beginning in the mid-2010s. These appearances brought his decades of field research into contact with audiences that the academic community’s treatment of catastrophist hypotheses had kept from the material. The effect was to consolidate public interest in the Younger Dryas impact hypothesis and in the broader question of whether the conventional chronology of human civilization is adequate to the evidence.

The Scablands and the Evidence of Catastrophic Flooding

The foundational empirical work in Carlson’s project is his field research on the Channeled Scablands of eastern Washington state. The scablands are a vast landscape of stripped basalt, giant current ripples measured in hundreds of feet from crest to crest, massive gravel bars deposited at altitudes inconsistent with any ordinary river flow, and drainage channels hundreds of feet deep cut into solid rock. The landscape was first proposed to be the product of catastrophic flooding by J Harlen Bretz in the 1920s. Bretz’s thesis — that the scablands were carved in days or weeks by floodwaters of unprecedented magnitude — was rejected by the geological establishment for more than four decades on the grounds that it violated the principle of uniformitarianism that had been the foundation of the discipline since Lyell. Bretz was eventually vindicated, receiving the Penrose Medal in 1979 at the age of ninety-six, after the evidence accumulated to a point where the catastrophic interpretation could no longer be denied.

Carlson has extended this work by documenting the geological evidence for multiple discrete flood events in the scabland record, arguing that the landscape was not carved by a single catastrophic outburst but by a series of recurrent events, each of enormous magnitude. The mechanism involved the repeated collapse of ice dams holding back glacial Lake Missoula, with each collapse releasing volumes of water that modern estimates place in the range of hundreds of cubic kilometers discharged within days. The cumulative effect of these repeated outbursts is the landscape that Bretz first described and that Carlson has continued to map in detail.

The significance of this field research for the broader catastrophist thesis is that it establishes, on uncontested evidence, that the geological history of the recent past includes events of a scale that is outside the experience of the instrumental era and outside the category of processes that uniformitarian models treat as normal. Once the possibility of such events is admitted in one location, the framework for interpreting anomalies elsewhere in the geological record shifts. The question becomes whether similar events have occurred at other times and places, and whether their signature can be recovered from the stratigraphic record.

The Younger Dryas Boundary and the Impact Hypothesis

Carlson is one of the leading independent popularizers of the Younger Dryas impact hypothesis developed by Firestone, West, and Kennett and their collaborators. His contribution to the public discussion has been to integrate the peer-reviewed geochemical evidence — the nanodiamonds, microspherules, platinum group metals, and magnetic spherules at the Younger Dryas boundary — with the hydrological evidence he has personally documented in the scablands, and with the mythological and archaeological evidence that Graham Hancock and others have assembled. The resulting synthesis describes a compound event in which a cometary fragmentation and airburst over the North American ice sheet triggered rapid melt, catastrophic flooding, sudden climate reversal, and the extinction of most North American megafauna within a compressed time window approximately 12,800 years before the present.

The hypothesis remains contested in the academic literature. Critical reviews have challenged the reproducibility of the geochemical markers at specific sites and questioned the adequacy of the proposed mechanism for the observed effects. Responses from the original research team and from independent laboratories have addressed many of these criticisms, with additional evidence accumulating at new sites on multiple continents. The dispute is not resolved, but the body of evidence supporting the hypothesis has grown rather than diminished in the years since the original 2007 publication.

Carlson’s position, articulated across dozens of public presentations, is that the evidence for the impact hypothesis has crossed the threshold of reasonable doubt and that the continued resistance from portions of the academic community reflects institutional rather than evidentiary considerations. He has been careful to present the evidence in detail and to acknowledge the points of genuine dispute, distinguishing his approach from less rigorous popular catastrophism.

Sacred Geometry and the Cosmological Architecture

Parallel to the field geology is Carlson’s long-standing research into sacred geometry and the cosmological proportions encoded in monumental architecture. Drawing on the tradition established by Schwaller de Lubicz at Luxor and on the earlier work of John Michell, Keith Critchlow, and Robert Lawlor, Carlson has documented the geometric proportions embedded in sites ranging from Gobekli Tepe through the Egyptian pyramids to the Gothic cathedrals, arguing that the same canonical proportions recur across cultures and epochs in a way that implies a common intellectual tradition rather than independent invention.

The specific proportions at issue are those derived from the harmonic series, from the ratios between planetary orbital periods, and from the geometry of the Earth–Moon–Sun system. Carlson has argued that the builders of these monuments were working with an integrated understanding of astronomy, mathematics, and proportion that constitutes a coherent intellectual system, and that this system predates the conventional beginning of civilization by a substantial margin. The implication is that the civilization that built Göbekli Tepe was drawing on a tradition already old at the time, and that the tradition is what survived the Younger Dryas event to be transmitted through the mystery schools into the historical period.

This work connects directly to the catastrophist thesis by providing the mechanism by which pre-cataclysm knowledge could have been preserved across the reset. Monumental geometry is resilient in a way that written knowledge is not. A tradition of sacred proportion encoded in stone and in the ritual use of stone can survive the destruction of libraries and the scattering of populations, to be recovered and extended by successor civilizations that learn to read the stones. On Carlson’s account, the Egyptian, Mesoamerican, and Gothic traditions are all downstream of such a recovery.

The Precessional Clock and the Timing Question

The integration of Carlson’s field geology with his sacred geometry work generates a specific hypothesis about the timing of the cataclysm cycle. The precessional cycle at approximately 25,920 years is long enough to carry the solar system through significant changes in its relationship to the galactic plane, through periods of varying cosmic-ray flux, and through statistical windows of higher cometary and meteoroid flux as the Earth’s orbit intersects debris streams from fragmented parent bodies. The alignment of the precessional cycle with the catastrophic record, on Carlson’s reading, is not a coincidence but a causal relationship, with precessional geometry modulating the probability of impact and related events across the cycle.

The ancient astronomers who built the monuments, on this reading, were tracking the precessional clock precisely because they knew it was connected to the recurrence. The calendar and the temple and the pyramid were instruments for measuring the cycle and for preserving the measurement across the transitions. Santillana and von Dechend’s Hamlet’s Mill provides the scholarly foundation for the argument that the mythological record encodes precessional knowledge in narrative form, and Carlson has extended this thesis by linking the encoded knowledge to specific geological events and specific architectural proportions.

The practical implication is that the current position in the precessional cycle can be used to estimate the proximity of the next window. Carlson has declined to commit to specific dates in the manner of some other catastrophist researchers, but the trajectory of his argument places the current generation within a period of elevated risk relative to the long-term average, and his advocacy has emphasized preparedness and the recovery of the ancient knowledge as practical responses to the recurrence.
