“…Given the influence of the individual mapper on accuracy and precision, it may be beneficial and desirable for multiple mappers to complete (initially) independent field surveys and examination of remotely-sensed datasets to enhance reliability and reproducibility (cf. Hillier et al, 2015;Ewertowski et al, 2017). However, this approach would only be applicable in collaborative efforts and may be impractical due to various factors (e.g.…”

Geomorphological mapping is a well-established method for examining earth surface processes and landscape evolution in a range of environmental contexts. In glacial research, it provides crucial data for a wide range of process-oriented and palaeoglaciological reconstruction studies; in the latter case providing an essential geomorphological framework for establishing glacial chronologies. In recent decades, there have been significant developments in remote sensing and Geographical Information Systems (GIS), with a plethora of high-quality remotely-sensed datasets now (often freely) available. Most recently, the emergence of unmanned aerial vehicle (UAV) technology has allowed sub-decimetre scale aerial images and Digital Elevation Models (DEMs) to be obtained. Traditional field mapping methods still have an important role in 'work streams' that recognise the different approaches typically used in mapping landforms produced by ice masses of different sizes: (i) mapping of ice sheet geomorphological imprints using a combined remote sensing approach, with some field checking (where feasible); and (ii) mapping of alpine and plateau-style ice mass (cirque glacier, valley glacier, icefield and icecap) geomorphological imprints using remote sensing and considerable field mapping. Key challenges to accurate and robust geomorphological mapping are highlighted, often necessitating compromises and pragmatic solutions. The importance of combining multiple datasets and/or mapping approaches is emphasised, akin to multi-proxy/-method approaches used in many Earth Science disciplines. Based on our review, we provide idealised frameworks and general recommendations to ensure best practice in future studies and aid in accuracy assessment, comparison and integration of geomorphological data. These will be of particular value where geomorphological data are incorporated in large compilations and subsequently used for palaeoglaciological reconstructions. Finally, we stress that robust interpretations of glacial landforms and landscapes invariably requires additional chronological and/or sedimentological evidence, and that such data should be collected as part of a coupled inductive-deductive approach.

Zarys treści: W zachodniej części piaskowni Łubienica-Superunki, położonej na Wysoczyźnie Ciechanowskiej (północne Mazowsze), stwierdzono występowanie struktur peryglacjalnych, takich jak: inwolucje, bruk peryglacjalny oraz pseudomorfozy po dużych epigenetycznych klinach mrozowych z wypełnieniem lodowo-piaszczystym (ang. composite wegdes). Struktury te wykształcone są w większości bezpośrednio pod współczesną glebą i warstwą piasków pokrywowych o małej miąższości poza jednym z klinów, który występuje w obrębie osadów fluwioglacjalnych w transgresji młodszego stadiału zlodowacenia warty. Słowa kluczowe: inwolucje, bruk peryglacjalny, kliny mrozowe, Równina CiechanowskaAbstract: In the western part of the Łubienica-Superunki sand pit, located on the Ciechanowska Upland (northern Mazovia), periglacial structures were observed such as: involutions, periglacial pavement and large epigenetic composite wegde psuedomorphs. The structures occur usually below contemporary topsoil and thin layer of cover sands, besides one frost wedge, which is developed in fluvioglacial sediments from transgression of younger Saalian ice sheet.
