The rock mass of fluvial and fluvioglacial deposits of the Late Holocene has been studied at the altitude of 1830 m a.s.l. using the palynologic, carpologic, geomorphologic, and geochronologic methods. It was ascertained that in the mid-Subatlantic period the area of the present-day beech elfin woodland was occupied by a belt of alpine meadows. Thus, the lower border of alpine meadows ran 370-400 m lower than the recent level, pointing to a rather significant cooling of the climate that occurred from ca 2nd cent. A.D.

The geological map shows the border area between the polyphase (late Mesoproterozoic and Cambrian) deformed Sivorg Terrane and the Kottas Terrane where a pervasive Cambrian tectonometamorphic overprints is lacking. Geological revision mapping was carried out during the Antarctic Expedition 2000/01 of the Alfred Wegener Institute for Polar and Marine Research. Topographic data were obtained through stereoscopic aerial photo interpretation. The photogrammetric photo flights were undertaken in 1986 by the Institut für Angewandte Geodäsie, Frankfurt. Horizontal ground control points required for aerial photo interpretation were determined by means of Doppler satellite observation during the 2nd German Neuschwabenland Expedition 1985/86. Vertical ground control points were taken from unpublished map drafts at 1:100 000 scale by Norsk Polarinstitutt, Oslo. The elevation above mean sea level was transferred to Heimefrontfjella barometrically. For this reason assertions concerning the absolute elevation (referred to sea level) are uncertain. Contours and spot heights presented on the map were obtained from the photogrammetric evaluation of the photography taken in 1986; relative elevation data (height differences) are accurate to approximately ±10 m.
