Week of March 16: Deep Shafts Found Beneath Giza Plateau, 1M-Year-Old Skull Discovery, and More

Surveys on the Giza Plateau have documented previously unknown subterranean shafts reaching depths of nearly 50 feet with tunnels branching toward the pyramids and evidence of flowing material beneath them, while precision tool marks on basalt flooring suggest advanced technology beyond hand-operated methods. A 1-million-year-old skull discovered in Hubei Province, China has been reclassified as Homo longi and challenges conventional models of human brain evolution by suggesting large brains may have developed in multiple lineages far earlier than believed. An 11-day expedition in New Mexico’s Gila Wilderness has documented previously unknown Mogollon archaeological sites and a southeast-facing petroglyph panel on pink volcanic rock, while excavations at Peru’s Coricancha complex reveal vitrified stonework with impossibly precise polygonal joints predating Inca construction.

New Excavations & Fieldwork

A pink volcanic rock face bearing a stick figure petroglyph accompanied by an object in the sky has been documented at an undocumented site in New Mexico [V2] [V1]. The geology of this rock face shares similarities with formations found at Gila Cliff Dwelling National Monument [V2] [V1]. The petroglyph has survived the passage of time because an overhanging rock formation protects it from the elements, though the majority of the original rock art panel has eroded over approximately 1,000 years [V2] [V1]. Scholars believe the entire rock face was likely covered with ancient art before erosion reduced it to the surviving elements [V2].

Petroglyphs such as this one were created using a striking stone to peck designs into rock faces [1]. The site faces southeast toward the winter sunrise, consistent with known Mogollon orientation preferences for ceremonial and astronomical sites [V1] [V2]. While the volcanic rock appears pink, the exact geological composition—whether rhyolite, andesite, or tuff—has not been determined through petrographic analysis [V2] [V1], leaving room for future scientific investigation at this protected New Mexico location.

Remote Sensing & Technology

Recent surveys have documented two previously unknown subterranean shafts on the Giza Plateau reaching significant depths beneath the bedrock. The first shaft measures approximately 30 feet deep, while a second shaft has been precisely measured at 47.8 and 47.6 feet deep using laser technology—a depth equivalent to approximately five stories in height [V3]. The shafts contain tunnels that branch toward the pyramids and the Sphinx, and investigators conclude they are intentionally engineered structures rather than natural formations [V3]. Sand fills the bottom of the shafts, with researchers suggesting this indicates passages extend deeper below the current measured depths [V3].

Equally striking is evidence of advanced precision technology found at the site. Tool marks on basalt flooring show straight cuts without wobbling or teetering angles that would result from hand-operated saws, leading investigators to conclude that copper saw and sand methods could not produce cuts of the observed precision on hard stone [V4]. The saw marks are embedded within the stone itself, indicating that cuts were made on-site rather than pre-fabricated elsewhere [V4]. Additionally, purple and reddish-colored veins emanate from beneath the pyramids, extending outward and downward, while hollow sections containing rust-colored substances were detected within the rock along what investigators describe as “leak lines,” suggesting liquid or material may have been flowing from the pyramid interior [V5].

Bioarchaeology & Ancient DNA

The discovery of the Yunxian 2 skull in Hubei Province, China, in the early 1990s initially yielded a heavily crushed and distorted fossil that defied straightforward analysis [V6]. The individual lived roughly 1 million to 1.1 million years ago according to geological dating [V6]. This finding challenges the standard model of human brain evolution, which holds that substantial brain expansion was a slow, gradual climb culminating with Homo sapiens [V7] [5]. Instead, the research suggests multiple human lineages may have developed large brains much earlier than previously believed. The fossil’s thick brow ridge and long, low braincase resemble earlier hominids like Homo erectus, yet its proportions do not fit neatly into textbook expectations for its time period [4] [V7]. The skull was previously classified as Homo erectus, but new morphological analysis indicates it belongs to the Homo longi lineage, a sister species to Denisovans [V6] [2] [6] [3].

Architecture & Monuments

The Coricancha complex in Cusco contains stonework that challenges conventional understanding of ancient construction techniques. Massive andesite blocks interlock in complex polygonal patterns with joints of extreme precision—researchers note that razor blades cannot slide between them [V9]. Yet beyond mere precision, the stone surfaces exhibit glassy, vitrified characteristics, with a subtle sheen along seams and exposed faces that appears almost glazed [V9]. The contact points between stones appear smoother, tighter, and in some cases slightly fused, suggesting a bonding process not fully understood [V9]. Notably, the grain size at some joint interfaces appears finer than in the untouched stone body, indicating possible thermal or chemical modification at these points [V9].

Some researchers believe these core foundations predate Inca construction, with pre-Inca remnants of uncertain origin incorporated into the structure [V9]. The foundations also demonstrate sophisticated earthquake-resistant design through zigzagging joints that increase friction between blocks—a practical engineering response to the region’s seismic activity [V9]. Some stones display curious round holes and unusually smooth curved surfaces whose purpose remains unexplained [V9].

Ancient Art

Archaeologists have documented that primitive geometric symbols painted with red ochre lie beneath Christian wall paintings in Cappadocia cave churches, including swastika symbols found under frescoes [V11]. These findings suggest that Christian imagery in the region was often superimposed over much older symbolic traditions. The documented geometric motifs include circles, zigzags, triangles, pyramids, and animal representations [V11]. A rosette cross symbol discovered under the oldest Christian paintings has been identified as a pre-Christian sun symbol [V11], indicating the persistence of earlier religious concepts within the region’s spiritual landscape.

The red ochre geometric symbols predate Christianity by thousands of years and appear in similar forms in Naqada predynastic Egyptian culture [V11]. Cross and sun cross symbols were used by Sumerians, Assyrians, Hittites, and Persians in ancient Near Eastern traditions [V11], demonstrating that these symbolic forms were widespread across the region long before the establishment of Christian churches in Cappadocia.

In Brief

The Aurignacian symbol system reveals a striking pattern of deliberate conventions: crosses appear exclusively on zoomorphic imagery and tools, while dots adorn anthropomorphic figurines and felines [8] [V15] [7]. Crosses constitute the most frequently occurring signs yet never mark human figures [8] [V15] [7]. This selective distribution cannot be attributed to material constraints since artisans carved both figurines and tools from ivory, which offered equivalent surface qualities for either symbol type [V15]. The patterning suggests these were meaningful conventions, not random decoration.

Aurignacian symbols show deliberate conventions: crosses on animals, dots on anthropomorphs

The statistical regularities within this sign system remained stable for approximately 10,000 years, pointing to cultural transmission across generations [V15] [V14]. Artifacts from southwestern Germany, the Dordogne region of France, and Belgium date to 43,000-48,000 years ago [V13]. The system eventually disappeared, with researchers suggesting possible disruption from subsequent migration waves transitioning from Aurignacian to Magdalenian cultures and eventually to farming populations [V15].

The casing stones stripped from the Great Pyramid were removed primarily in the late 14th century, not as a consequence of the 1303 earthquake as commonly believed [V19]. Ludolf von Sudheim observed the Great Pyramid still bearing its polished limestone casing in 1336, yet by 1395 a French nobleman from Anglur documented that approximately half the casing stones had already been removed [V19] [V16]. The systematic destruction accelerated under Bahri Sultan An-Nasir Hasan, who stripped the majority of the remaining casing stones in the 1350s to supply construction materials for Cairo’s rebuilding following earthquake and military damage [V19] [9]. The white limestone blocks, quarried from Tura approximately 15 kilometers upriver from Giza, had originally been polished to gleam brilliantly in sunlight, giving the monument its characteristic appearance [10].

The uppermost five courses of the Great Pyramid were destroyed between 1395 and 1798, erasing inscriptions and eliminating the summit’s original pointed appearance [V18]. A striking sequence of eyewitness accounts reveals the final destruction occurred shortly before 1799: Jacques Rober documented an intact summit still bearing inscriptions in 1798, while Edme Jama noted on January 5, 1799 that stones had recently been removed from the summit, indicating the last remnants of the pyramid’s casing vanished within mere months [V18].

A recent 11-day expedition in New Mexico’s Gila Wilderness successfully documented at least two previously unknown Mogollon archaeological sites in uncharted portions of the West Fork Gila River [V21]. The expedition, led by explorer-anthropologist Luke Caverns, was his first traditional unsupported expedition [V20]. Beyond the archaeological discoveries, the team also surveyed for jaguar migration signs while navigating the region’s challenging terrain [V20].

The expedition sought to determine the extent of Mogollon settlement in the Gila region [V21], navigating extreme terrain including river crossings, narrow canyons, and multiple canyon systems accessible via Iron Creek [V21]. Documentation from the expedition reveals that Mogollon people characteristically sought southeast-facing ridges with natural rock cavities for dwellings [V21], a settlement pattern that guided the team’s survey strategy through this remote wilderness area.

A complete Book of Enoch manuscript is preserved at a monastery on Lake Tana, Ethiopia, representing one of the most significant surviving copies of this ancient text [11] [V22]. This manuscript is guarded by a single monk assigned for life, reflecting the immense spiritual responsibility placed upon its custodian [11] [V22]. The Book of Enoch holds canonical importance in Ethiopian Orthodox tradition and is not considered apocryphal as it is in Western Christian denominations, underscoring its central role in Ethiopian religious practice [V23] [V22]. The manuscript is studied at the highest level of monastic training, reserved for the most advanced tenth-level scholars within the tradition [V22].

The text’s significance is further illuminated by historical context: James Bruce recovered three Ge’ez-language copies of the Book of Enoch during his 18th-century travels in Abyssinia [V24]. Ethiopia contains over 600 active monasteries that continue these centuries-old traditions of manuscript preservation and scholarly study [V23].

The archaeological record reveals a striking transformation in Britain’s economy following the third-century crisis. Cities persisted but hollowed out economically, becoming administrative centers while small towns in the countryside took over manufacturing and trade functions. The most visible marker of this shift was material culture itself—pottery shifted from wheel-made glazed plates to hand-made crude forms, and coinage volume plummeted by approximately 425 AD [V25]. Yet emerging evidence complicates this collapse narrative: sediment core analysis suggests Britain’s economy may have been more resilient after Roman rule than previously assumed, with metal production continuing uninterrupted into the Viking Age and beyond [12] [13].

The most dramatic evidence for settlement disruption comes from Strath of Kildonan in Scotland, where approximately 2,000 stone roundhouses appear to have been abandoned around 1150 BC [V26]. This abandonment coincides with a broader trend across Scotland, where surviving roundhouses decreased markedly in average size from roughly 78 square meters around 1000 BC to approximately 40 square meters around 800 BC [V26]. Notably, this shrinkage began in western Scotland and progressed eastward across the country [V26], suggesting a gradual climatic or environmental pressure affecting communities in sequence rather than a sudden catastrophic event.

Hekla 3 eruption linked to Bronze Age settlement changes in British Isles around 1150 BC

Volcanic tephra from the Hekla 3 eruption has been recovered in soil core samples from Scotland and Ireland, offering a potential mechanism for these disruptions [V27] [V26]. Scholars theorize that acid rain from volcanic sulfur may have altered soil pH, devastating agriculture and compounding pre-existing drought conditions [14] [V26]. Higher elevation cultivations were largely abandoned within two centuries following the eruption period [V26]. However, the correlation between Hekla 3 and settlement collapse remains debated. The 1150 BC date commonly cited for the eruption derives partly from the theory being tested rather than independent dating, creating a risk of circular reasoning [V26]. Additionally, the roundhouse size data and Strath of Kildonan abandonment pattern come from secondary sources interpreting archaeological data rather than primary excavation reports, warranting caution about the strength of the proposed connection between volcanic activity and settlement change.

The Bridge of the Gods holds a central place in Pacific Northwest Native American cosmology, with the most widely recorded version featuring Mount Hood (Wy’east) and Mount Adams (Pahto/Klickitat) as rival brothers locked in violent conflict over the affections of a woman associated with Mount St. Helens (Loowit) [V30] [16]. Accounts diverge notably on Loowit’s characterization—she appears as a beautiful young woman in some traditions and as an ugly old hag in others [V30] [16] [15]. A separate Thunderbird version describes the bridge itself as formed from the body of a giant bird [V30]. These stories are set in a primordial “time when animals could speak,” situating them within broader creation mythology, and multiple variant versions exist with different timelines and character roles [V30]. Intriguingly, geological science has corroborated these accounts—the Bonneville landslide event that created the bridge has been dated through lichen analysis, tree ring analysis, carbon dating, and Native American accounts of a massive, dark tunnel with unnaturally slow-moving water present in almost every oral tradition [V28] [V29].

Rising dramatically from the central Sri Lankan landscape to a height of approximately 650 feet, Sigiriya’s summit appears almost perfectly flat—a feature suggesting deliberate shaping with remarkable precision [V31]. While mainstream archaeology attributes the fortress structures to 5th-century King Kashyappa (477–495 CE), evidence of human activity at the site stretches back thousands of years to the Mesolithic period, complicating a simple narrative of construction [V31] [19] [20].

The rock contains a sophisticated hydraulic system with canals, reservoirs, and retaining structures that remain partially functional today, including a granite water tank carved into the summit measuring approximately 90 feet long, 68 feet wide, and 7 feet deep—requiring the removal of roughly 3,500 tons of granite [V31] [18] [19]. This summit reservoir maintains water equilibrium during monsoon cycles without drying or overflowing, indicating an engineered drainage system [V31] [20]. However, the carved tank displays long sweeping scoop marks rather than typical hammer and chisel scars, suggesting an unidentified tool or technique, while narrow channels, grooves, and drilled holes appear on rock faces in places without footholds [V31]. Researchers continue to debate whether these construction features fit comfortably within the conventional 5th-century attribution or suggest older, more advanced engineering methods [V31] [17].
