The Ob is Russia's third-longest river. It flows slower than a person can walk. Its surface is almost never rippled.
And yet, it still claims people every year.
I spent several months poring over the archives of the Ministry of Emergency Situations, expedition reports of Soviet geologists, ethnographic records, and conversations with those who live by this river.
This video is about what I found.
Why the Ob's dark water makes a person blind at a depth of just 20 centimeters.
Why locals divide the river into places that "give" and places that "don't give."
Why the Khanty knew things about this river that hydrologists only described 200 years later.
And why Soviet boarding schools destroyed a system of knowledge that had worked for six thousand years.
If you enjoy dark documentaries, natural horror, ethnography, and real places that are more frightening than any legend, this video is for you.
