A cryonival morphogenetic system of high mountains of the West Carpathians (in Slovakia) is located by the author in the vertical belt from 1,550 (to 1,700) m a. s. l. as far as 2,660 m a. s. l. Geoecological conditions (Tab. 1), types of a relief (Tab. 2) as well as actual types of high-mountain landscape surfaces in the West Carpathians are characterized. A height of the Pleistocene snow line fluctuates between 1,350 m a. s. l. and 1,760 m a. s. l. there. A present-day timberline (average from 1,185 to 1,438 m a. s. l.) was depressed about 100 to 280 m on average. After the active landscape surfaces are demonstrated both erosive disaster due to surface runoff (as a rate of potential water erosion) and the real rate of such present-day morphogenetic processes as water erosion, mass movements (rock-fall, creep, debris flow), eolian processes, nivation and cryogenic processes. Mean lowering of the surface above the timberline amounts to 0.27 mm per annum
