Features of the Holocene History of the Relief and Soft Rocks Formation in the Basin of the Bakhapcha River (Kolyma River Tributary)
The Bakhapcha River banks were among the first objects of geological studies conducted in the Kolyma R. basin, but the geomorphology of this area has still been weakly researched. In the late 20th century, applying remote sensing and field methods permitted to identify its peculiar geologic and geomorphologic characters: well-expressed end moraines formed by Late Pleistocene glaciers, anomalous rapids, repeated coincidence of high rapids and quite low grades of the river profile, insignificant river and flood-plain deposits, development of major river captures over the Maltan-Bakhapcha R. area of the Okhotsk-Kolyma divide, and a major swarm of paleoseismic dislocations of the Holocene in Bakhapcha Mountains. The Early Holocene process of glacier-caused mud-rock flood in the interfluve area of the Dyadya Vanya and the Svetly creeks interfluve has been reconstructed.
