Geometric stone settings in the Yustyd Valley and its surroundings (Altai Mountains, Russia): Bronze Age 'virtual dwellings' and associated structures

A recent detailed survey in the valley of Yustyd and its surroundings allowed to set up a basic description of the type and some related types. Recent excavation suggests a date in the Early Bronze Age. According to E. Jacobson-Tepfer's suggestion, we propose that these monuments are ritual monuments, in a funerary context, possibly as location for exposition of the body or sky burials.
