In this paper we deal with certain structures, very widely distributed in the Baikal region, that are related to permafrost beds, and we describe their physical properties. Examples are given to show the ineffectiveness of the geomorphological method of investigating deep structure, an ineffectiveness due to the absence, in permafrost zones, of any inheritance of structural form in depth. A distinct relationship is noted between gravity anomalies and features of the geological structure in permafrost zones. It is shown that for positive uplifted structures related to permafrost, negative gravity anomalies are characteristic.
