The Fire Eagle's Nest: What Built Siberia's Patomskiy Crater?

There are places on the map that seem to resent being found, and the Patom Highlands of eastern Siberia are among them. To stand before the thing the local Yakut hunters called the Fire Eagle's Nest, you must travel far beyond the gold town of Bodaibo, into a roadless country of larch and permafrost where the nearest settlement is a rumor and the taiga swallows every trail behind you. It was here, in the summer of 1949, that a young Soviet geologist named Vadim Kolpakov came through the trees and stopped short, because rising out of the forested slope in front of him was something that had no business existing at all: a vast pale mound of broken gray stone, cone-shaped and flat-crowned, as wrong against the green hillside as a cathedral dropped into a swamp.

Kolpakov's first thought, he later admitted, was that he had stumbled on the waste heap of a mine. But there was no mine. No road ran to the place, no settlement lay within a great distance, and the labor of hauling a million tons of shattered rock into a cone forty meters high would have defeated an army working for years. His second guess was a volcano, yet this corner of Siberia has never had volcanoes, and the mound was built of the same limestone that lay beneath his boots, not of anything that had ever been molten. Whatever raised it had done so from below, forcing the region's own bedrock up through itself and leaving it standing in the forest like a wound that would not close.
