Dimitri Sobolev

Dimitri Sobolev was a Kazakh cinematographer accompanying Anatoli Boukreev and Simone Moro on their 1997 winter expedition to Annapurna I. His brief appearance in the account becomes inseparable from the expedition’s fatal avalanche: he was below Boukreev when the snow and ice swept down, and neither man answered Moro’s calls afterward. The book ultimately names Sobolev alongside Boukreev in its memorial to the two climbers lost on the mountain.

Identity and expedition role

Sobolev joined Boukreev and Moro as the expedition’s cinematographer, intending to document their attempt on Annapurna I by its South Face. The three reached Annapurna Base Camp by helicopter on December 1, 1997. Their prospects initially seemed promising, although deep, unconsolidated snow forced them to alter their planned route.

The revised plan aimed to limit exposure to avalanche danger. For three weeks, the climbers worked through deep snow to establish Camp I at 5,200 meters. From there they intended to fix ropes to a ridge a little above 6,000 meters and traverse toward the summit, accepting a longer and more arduous route in hope of spending less time on Annapurna’s slopes.

The avalanche on Christmas Day

On December 25, Boukreev, Moro, and Sobolev left Camp I with the first light. They spent the morning fixing ropes and advancing toward the ridge. At 12:27 p.m., Moro was at 5,950 meters; below him, Boukreev and Sobolev were climbing a gully. Boukreev carried a coil of rope intended for the final section to the ridge.

A cornice broke away from the ridge above, sending a large mass of ice and snow down the mountain. Moro saw it coming and called out to Boukreev. Boukreev and Sobolev looked toward the warning and saw the avalanche. Moro reported that Boukreev began moving up the sloping side of the gully, but the account does not establish what happened to Sobolev in the avalanche itself.

The avalanche swept Moro down near Camp I. After regaining consciousness, he called into the debris field for about twenty minutes, but received no answer from either Boukreev or Sobolev. A Sherpa who had remained at camp helped make a helicopter evacuation possible for Moro; Sobolev’s fate was not resolved in the scene.

Disappearance and remembrance

The narrative leaves Sobolev among the two men who did not return from the avalanche. In the book’s memorial passage, his name appears with Boukreev’s in the stark closing words, “Dimitri Sobolev. Anatoli Boukreev. Not forgotten.” That remembrance gives Sobolev a final presence in an account otherwise marked by the absence of any response to Moro’s calls.

The evidence identifies Sobolev’s role, his position on the mountain immediately before the avalanche, and the fact that Moro could not find or hear from him afterward. It supplies no further account of his background or a separate personal trajectory, so his characterization remains tied to the expedition and its closing memorial.
