This field experience was only made possible thanks to the support of the Bulgarian society for regional cultural studies and the Institute for anthropological field-research/New Bulgarian University. I have to thank especially Yulian Konstantinov and Petia Mankova who invited me to join their expedition, offered me their whole infrastructure in the Kola as well as some empirical data from their previous expeditions. My acknowledgements go also to the reindeer herders from brigade No. 1 of Krasnoshchelie as well as to my informants from Revda for their precious collaboration.
