The article presents the results of the first detailed geomorphological mapping of the Žiarska, Jamnicka, Raekova, and Bystra Valleys, situated on the southern slope of the Western Tatra Mountains. The field work was supplemented by digital topographic as well as statistical analysis of rock glaciers distribution. The author focused on the distribution and morphological features of moraines and rock glaciers. Variability of both sets of deposits strongly reflects topographic influences on debris and snow accumulation. The main factor controlling the geometry of landforms was solar irradiance modified by the influence of the local cirque topography. Two generations of the rock glaciers indicate distinct phases of periglacial conditions during the Late Glacial period.

An empirical glacio-climatic relation (Ohmura et al., 1992) and meteorological data (temperature and precipitation) are employed to provide the elevation in the Tatra Mts. climate model, where conditions are suitable for hypothetical glacierisation (temperature-precipitation ELA). During the Little Ice Age (LIA) it is to have been 1.5 centigrade colder than during the warmest decades of the 20th century (Niedźwiedź, 2004); however, some scenarios are used to define precipitation amounts related to the vertical distribution in climate model and temporal variability. The results indicate that during both considered periods - the warmest decades of the 20th century and the coolest period of LIA - the climatic snowline (cSL) was placed in most cases above the highest Tatra Mts. summits and crests. However, its spatial arrangement was unequal. In the vicinity of Kasprowy Wierch, the modern cSL is assessed to be at ca. 2,450-2,650 m a.s.l. and that during LIA at ca. 2,300-2,450 m a.s.l. In the case of Lomnicky Štit (2,634 m) it was at the level of ca. 2,700–2,800 m a.s.l. (modern times) and ca. 2,600–2,700 m a.s.l. (LIA). The discrepancies in the cSL altitude between these two locations can be explained in part by exposition to the prevailing moisture transport and orographically-induced precipitation.

The landforms of the Chornohora Mountains and related geomorphological processes are strongly controlled by geological structure. Detailed geomorphological mapping of the Chornohora Range yielded evidence of deep-seated gravitational slope failures on the south-western slopes. These slope deformations were structurally predisposed and linked to the dip of bedrock strata and their resistance to erosion, as well as to cracks and faults within the flysch formations. This paper presents structural factors controlling the morphology of relatively poorly recognized, dip-adjusted south-western slopes of the Chornohora Mts. between Mt. Hoverla (2,061 m a.s.l.) and Mt. Pop Ivan (2,022 m a.s.l.).

Studies on the dynamics of geomorphologic processes occurring in the Tatras began in the 1950s and continue to pique the interest of researchers. The history of the study of Tatra relief morphodynamic changes is marked by certain breakthrough stages associated with the emergence of key works yielding multiplier effects. These works identified new directions and sparked new trends in geomorphologic research as well as inspired deeper analysis of the study area. A significant acceleration of geomorphologic research in the Tatras has occurred in the most recent decade. This resulted mostly from the use of complex monitoring of key dynamic geomorphologic processes and the use of lichenometric and dendrogeomorphologic methods, which enable the identification of complete event chronologies. The present study reviews the most important quantitative studies on the evolution and rate of contemporary geomorphologic processes in the Tatras as well as novel research data produced in the last several years. The authors note principal research directions and the discuss relevant works on the identification of contemporary and relict periglacial relief along with papers on the dynamics of slope and fluvial processes and anthropogenic erosion. The paper also describes certain tendencies observed recently in the realm of morphogenetic processes associated with ongoing climate change.
