Block topography in southern Yakutia and its erosional dissection

Abstract

Block structure is clearly pronounced in the southern Yakutia topography. Several topographic steps are distinguished, differing in absolute height and spatial orientation, the higher are the levels, and the more various is their orientation. One level cons-idered to be basal and to form pedestal for higher steps. At some regions increase in absolute heights proved to be inconsistent with the dissection density, certain boundaries of drainage density are established.
