71: History's Mysteries pt.2: A Soviet Secret

Updated: Jul 21


"What happened at the Dyatlov Pass?" Is one of the 20th centuries greatest historical mysteries. Dive into the chilling 1959 Dyatlov Pass saga. Picture nine seasoned hikers, led by Igor Dyatlov, slashing open their own tent in the dead of night, leaving frozen footprints, a still-glowing flashlight, and bodies ranging from textbook hypothermia to bomb-like rib breaks, singed socks, strangulation markings, missing tongues, and coffin-style snow graves. You’ll get heist-style team intros, spine-tingling diary excerpts, and a whirlwind tour of theories—paradoxical undressing, avalanches, covert Soviet weapons tests, ball lightning, UFOs, even Yeti attacks—plus no-nonsense insights from an ex-FBI agent and a Marin County coroner who flatly refuse “accident” as the answer. With key files buried, cameras torched, and NDAs locked down, every fresh clue only deepens the frostbitten mystery—six decades on, the true story of Dyatlov Pass remains entombed beneath the Ural snow in this Soviet Secret.

Our longest episode yet and we ... won't be doing this again.
