“…In this study, the LGM ELA values in the Rodna Mountains (∼1690 m) are higher compared with the values calculated for selected glaciers on the northern slope of the Western (1400 m) and High Tatra Mountains (1460-1525 m), which are located 400 km to the northwest in a cooler, more humid setting (Zasadni and Kłapyta, 2016;Engel et al, 2015;Makos et al, 2018;Zasadni et al, 2018), and lower than the ELAs calculated for Retezat Mountains in the southern Carpathians (1700-1850 m) (Ruszkiczay-Rüdiger et al, 2016.…”

In the eastern Carpathians the legacy of glaciation is preserved in several isolated mountain massifs. This paper presents new mapping results of glaciated valley land systems in the Rodna Mountains, the highest part of the eastern Carpathians (2303 m above seal level). In most of the glacial valleys, the maximal Pleistocene extent is marked by freshly shaped moraines, which are referred in this study as the Pietroasa glacial stage and regarded as the last glacial maximum (LGM) advance. Only in three valleys do older Şesura glacial stage moraines (pre-LGM, likely Marine Oxygen Isotope Stage 6) occur. On the basis of the geomorphological record, we reconstruct the extent, surface geometry, and equilibrium line altitude (ELA) of Pietroasa-stage glaciers. The local ELA pattern of north-exposed glaciers in the Rodna Mountains shows a rising trend towards the southeast, which suggests dominant snow-bearing winds and orographically induced precipitation from the west. This finding fits well with the dominant palaeo-wind direction inferred from other Carpathian proxies and confirms the dominance of zonal circulation pattern during the global LGM in central eastern Europe.

“…The mapping was also supported by field inspections in 2014, 2015 and 2016, during which c. 22 % of the mapped landforms, mostly located in the High Tatra Mts., were visited and their occurrence and delineation was verified. The survey was supported by previous literature reports and maps as well (Dzierżek & Nitychoruk, 1986;Kłapyta, 2008Kłapyta, , 2009Kłapyta, , 2010Kłapyta, , 2011Kłapyta, , 2012Kłapyta, , 2013aKłapyta, , 2013bKłapyta, , 2015Kłapyta & Kołaczek, 2009;Kotarba, 1988Kotarba, , 1991Kotarba, -1992Kotarba, , 2007Nemčok & Mahr, 1974;Zasadni & Kłapyta, 2016) that enable to extract precise information about the location of rock glaciers. However, we did not take over the literature information completely in all cases because the above mappings have emerged over several decades and had inconsistent data sources and mapping methodologies.…”

“…Consequently, there is occasionally no consensus among researchers regarding the landform identification or classification. An excellent example of this inconsistency is the debris accumulation located near the Zadni Staw Polski Lake in the Pięciu Stawów Polskich Valley in the Polish High Tatra Mts., which was classified as a rock glacier (Dzierżek et al, 1987), a moraine ridge (Makos et al, 2013a) as well as a rock avalanche (Zasadni & Kłapyta, 2016). Therefore, we carefully considered the integration of each individual previously mapped landform into the database mainly based on its appearance on aerial imagery in order to ensure the consistency of the inventory in terms of landform identification, classification and delineation throughout the whole region.…”

“…This imbalance began to equalize from 2004 when Kędzia, Kotarba, and Mościcki (2004) published their case study of a single rock glacier located near the Veľké Hincovo pleso Lake in the Slovak High Tatra Mts. and since then, a large amount of work related to rock glaciers has been carried out in both Slovak (Kłapyta, 2009(Kłapyta, , 2010(Kłapyta, , 2011(Kłapyta, , 2012(Kłapyta, , 2013a(Kłapyta, , 2013bPánek et al, 2015;Pánek et al, 2016;Zasadni & Kłapyta, 2014) and Polish territory (Kłapyta, 2008(Kłapyta, , 2013b(Kłapyta, , 2015Kłapyta & Kołaczek, 2009;Kotarba, 2007Kotarba, , 2013Makos, Rinterknecht, Braucher, Żarnowski, & Aster Team, 2016;Zasadni & Kłapyta, 2016) of the mountain ranges.

A detailed map of rock glaciers at a scale of 1 : 40 000 is produced for the Western and High Tatra Mts., Western Carpathians, based on remotely sensed mapping. We inventoried a total of 383 rock glaciers, covering a total area of 13.84 km 2. Most rock glaciers (85 %) are considered relict (without permafrost). These landforms have an average lower limit of 1684 m asl and occupy a total area of 12.50 km 2. In contrast, intact rock glaciers (containing permafrost) cover a total area of 1.34 km 2 and their average lower limit is located at 1986 m asl, which is 56 m above the previously suggested lower limit of discontinuous permafrost. The inventory adds new information about rock-glacier occurrence in the European highmountain areas and improves the understanding of present and past environmental conditions in the region.

Evaluating sources of uncertainty and variability in rock glacier inventories

This paper aims to evaluate sources of uncertainty and variability associated with rock glacier inventories compiled from remotely sensed imagery. To this end, we ran three mapping exercises in Kaiserbergtal, Austria. To evaluate interactions between mapping style and imagery resolution, we asked six operators to map and assess the degree of activity of all rock glaciers they could identify – first on Google Earth™ (GE) imagery and then on a set of higher‐resolution orthophotos and LiDAR‐derived images (LO) (Exercise 1). To compare the mapping attributes on a common set of rock glaciers, we asked 14 operators to delineate the outline of four designated rock glaciers (Exercise 2) and to classify the activity of 15 designated rock glaciers (Exercise 3) on LO. Results show strikingly high inter‐operator variability. Specifically, we show that the number of mapped rock glaciers on GE can vary up to a factor of 3, and that using LO lowers this figure to a factor of 2, while producing an increase in the number of mapped landforms, which become systematically smaller (Exercise 1). Examination of polygon outlines identifies highest inter‐operator variability at the transition with the rooting zone and, in polymorphic rock glaciers, on adjacent creeping lobes. Variability is higher for relict landforms (Exercise 2). Operators’ activity assessments, evaluated against an independent quantitative activity index (RGI), display reasonable agreement for active and relict landforms, whereas inactive counterparts meet least consensus and therefore are problematic (Exercise 3). We further show that this variability in mapping outcomes propagates across compound variables, and must be considered when assessing uncertainties and confidence levels of environmental evaluations that rely on rock glacier inventories, such as the lower altitudinal limit of discontinuous permafrost, or water storage potential. We call for an international effort to establish guidelines for rock glacier classification and mapping, towards more homogeneous inventories. © 2019 John Wiley & Sons, Ltd.
