In February 1959 nine Soviet ski hikers died on the slope of Kholat Syakhl in the northern Urals. This story follows them from their last diary entry to the ravine where the last four were found, using their own diaries and the 1959 case file, and tells the night the way the 2021 avalanche study and the 2020 prosecutors' review reconstruct it.

How to read it: start at chapter 1 and go in order. Each chapter tells the story first, then quotes the record it rests on and says what is actually known.

  1. 1. The Last Warm Night on the AuspiyaOn 31 January 1959 nine skiers from Sverdlovsk camp in the forest by the Auspiya River, and their leader writes the last entry in the group diary.23 to 31 January 1959
  2. 2. A Late Start and a Cut in the SnowOn 1 February the group leaves a food cache, starts climbing at three in the afternoon, and digs a flat place for the tent on the open slope of height 1079.1 February 1959, afternoon and early evening
  3. 3. The Night the Tent Was CutSome hours after dark the nine cut their way out of the tent from the inside and leave almost all their boots and coats behind.Night of 1 to 2 February 1959 (the exact hour is disputed)
  4. 4. Footprints to the CedarThe nine walk together for about a kilometer and a half down to a large cedar at the edge of the forest, light a fire, and some of them try to go back up.Night of 1 to 2 February 1959
  5. 5. The Den in the RavineThe last four go a short way into a stream ravine, build a floor of branches in the snow, and are found there in May under deep snow.Night of 1 to 2 February 1959; found 4 to 6 May 1959
  6. 6. "A Compelling Natural Force"The 1959 case closes without naming a cause, and reviews in 2019 and 2020, then a 2021 scientific study, point to a small avalanche.28 May 1959 to January 2021
  7. 7. The Questions That RemainThe avalanche account fits much of the record but not all of it, and other explanations still have supporters.1959 to today
This is a story, not proven history

This is a reconstruction, not a settled account. Every fact comes from a document listed under each chapter, but what the hikers saw, heard and decided that night is supposed, and the avalanche explanation is still disputed by relatives and researchers.

Questions people ask about What If We Could Follow the Dyatlov Group Through Their Last Night?

What happened at Dyatlov Pass?

On the night of 1 to 2 February 1959 nine hikers led by Igor Dyatlov cut their way out of their tent on the slope of Kholat Syakhl and went down toward the forest in deep cold without boots or coats. Six died of the cold and three of severe injuries. Their bodies were found between 26 February and May 1959.

What did the 1959 investigation conclude?

The investigator closed the case on 28 May 1959. He found no other people and no signs of a fight, and wrote that the hikers died from a force they could not overcome, a phrase translated as "overwhelming force" or "a compelling natural force". He did not say what that force was.

Was it an avalanche?

Russia's Investigative Committee in 2019 and the Prosecutor General's Office in July 2020 both named a snow avalanche as the most likely cause. A 2021 study by Johan Gaume and Alexander Puzrin showed how a small slab could have released hours after the group cut into the slope. Critics point out that searchers saw no clear avalanche debris, so the question is not closed.

Why did the Dyatlov hikers leave their tent?

The tent was cut open from the inside and almost all boots and outer clothing were left behind, so the group left suddenly. The avalanche explanation says snow fell on or threatened the tent. Other explanations include strong katabatic winds. The hikers left no record of what they saw.

Was there radiation at Dyatlov Pass?

A 1959 laboratory found slight beta contamination on some clothing, which partly washed off. The 2020 prosecutors linked it to the area of the 1957 Mayak nuclear accident, which two of the hikers had visited.
