Abstract
BTS measurements and nivologic profiles were recorded in the three sites particularly significant from the geomorphological point of view (area without permafrost, possible and certain permafrost areas) at the same day. Between permafrost areas and areas without permafrost, the crystalline characteristics of the snow in the basal layers are different. In the first case, snow is characterized by equithermic metamorphism (destructive), creating a feedback process which delays the snow melting in permafrost occurrence areas, improving the aggradation and conservation of permafrost.
