a new source of mummies is always welcome
Unlike other burial sites in Siberia, for example in the permafrost of the Altai Mountains, or those of the Egyptian pharaohs, the purpose did not seem to be to mummify the remains, hence the claim that their preservation until modern times was an accident. The soil in this spot is sandy and not permanently frozen. A combination of the use of copper, which prevented oxidation, and a sinking of the temperature in the 14th century, is behind the good condition of the remains today.
