Between 1932 and 1937, the output of the Dalstroy mine went from 511 kilograms of gold to 51.5 tons. The price of this astonishing growth was paid by the bodies of the prisoners, of whom there were 163,000 by the end of the decade. The writer Varlam Shalamov, Schlögel’s guide through this frozen Malebolge, explains it this way:To turn a healthy young man, who had begun his career in the clean winter air of the gold mines, into a goner, all that was needed, at a conservative estimate, was a term of twenty to thirty days of sixteen hours of work per day, with no rest days, with systematic starvation, torn clothes, and nights spent in temperatures of minus sixty degrees in a canvas tent with holes in it, and being beaten by the foremen, the criminal gang masters, and the guards.
