The Dalnegorsk "Height 611" UFO Crash

Dalnegorsk is a lead, zinc and boron mining town in Primorsky Krai, about 500 km from Vladivostok. One of its hills, Izvestkovaya Hill, rises inside the town itself. Its summit stands 611 metres high. It would become known as Height 611.

January 29, 1986, at 19:55 local time. A reddish-orange sphere appeared in the dark sky, about half the size of the Moon. It flew 700 to 800 metres up, parallel to the ground, at about 15 metres per second. No tail or trail. No sound.

Vladimir Kondakov, a mechanic, watched from the bus station. The sphere flew so low it seemed it would knock off part of the ore-processing plant's smokestack. "It was round, without any protrusions or indentations," he said. It seemed made of metal. Its colour resembled slightly heated stainless steel.

Near the hill, it began to rise and drop, and some witnesses counted six times. Each time it climbed, its glow grew brighter. Then it jerked and dived at an angle of 60 to 70 degrees, falling onto a rocky ledge near the summit like a rock. Most heard nothing, but one schoolboy at the foot of the hill reported a weak, dull impact. Reddish-white flames burned there for about an hour.

On 3 February 1986, Valery Dvuzhilny arrived with a field expedition. He was a local biologist and schoolteacher who headed the Far Eastern Committee for Anomalous Phenomena. On a burned patch about 2 by 2 metres, his team gathered about 70 g of lead droplets, 40 g of black glassy beads and 5 g of mesh. The mesh held quartz filaments about 17 µm thick, with gold wires inside. Two cameras were used at the site, but the film later developed as blank.

Samples went to Tomsk Polytechnic Institute and to institutes in Vladivostok and Khabarovsk. Chemist V. Vysotsky called the material "undoubtedly... a high-technology product and not a thing of natural or terrestrial origin." Dvuzhilny concluded it was "an automatic scout probe." He reported no rocket launches and no civil or military air traffic over Dalnegorsk that day.

No statement from the Soviet government or military has been found. Later isotope analysis matched the lead to a deposit in the Baikal region, a point sceptics count against an alien origin. Mikhail Gershtein of the Russian Geographical Society backed V. F. Psalomshchikov's explanation: a drifting reconnaissance balloon with a thermite self-destruct charge, arguing that 15 m/s is typical of the wind at that height. Yuri Platov of IZMIRAN called it a technical experiment, though no evidence was offered. Physicist Yuri Rylkin suggested a plasmoid, while supporters considered a meteor unlikely because the object was slow and left no trail.

On 6 February, two yellowish spheres reportedly flew to the site, circled it four times and vanished in a flash. In November 1987, 33 objects were reported over eastern Primorye. Marina Popovich later named Dalnegorsk among five sites where, she claimed, the KGB recovered crash fragments. Tunguska was on the same list.

The Sightings episode of 3 April 1995 carried the story to Western viewers, and the nickname "the Soviet Roswell" followed. Vadim Chernobrov led a Kosmopoisk expedition in 2004. Today a model spacecraft stands on the summit plateau, and a festival, "611 Steps to the Stars," has run since 2018. In 2024 priest Andrey Vasyakin asked for the monument's removal. The town refused.
