Deep in the Siberian wilderness, along the Vilyuy River basin, lies an area known by the locals as "Uliuyu Cherkechekh" (The Valley of Death). For centuries, local legends and modern discovery reports have pointed to an incredible mystery in this region regarding the "Olguis"—massive structures made of a reddish metal that resemble giant, overturned pots buried in the ground. Locals claim this mysterious metal is as sharp as a razor and inexplicably never rusts.
The physical effects reported by those who encounter them are chilling; there are numerous accounts of hunters who stayed inside or near these "cauldrons" suffering from hair loss, developing sores that wouldn't heal, and falling into a "deadly weakness"—all classic symptoms of radiation poisoning. These eerie reports are often linked to even older tales of "one-eyed giants in metal suits" living beneath the structures, leading modern researchers to suggest they may be part of an ancient, automated robotic system.
The most provocative theory regarding their purpose is that these cauldrons act as a protective shield for Earth. It is claimed that they form an automated defense system designed to intercept celestial threats, such as the massive 1908 Tunguska Explosion, which some believe was caused by a plasma sphere fired by this very system. While geologists in the 1930s and researchers like Ivan Mackerle in 2006 used GPR and drilling to detect hard, metallic, dome-shaped structures beneath the marshes, a full excavation has never been completed, leaving the true nature of the Valley of Death buried under the Siberian permafrost.
