Uncertainties about landscape evolution under cold, nonglacial conditions raise a question fundamental to periglacial geomorphology: what and where are landscapes? To answer this, with an emphasis on lowland areas, the present study distinguishes between characteristic polygenetic landscapes, considers how complete is footprint of periglaciation? Using conceptual framework sensitivity change, a...

the main issues about relation between climate and relief in the romanian geomorphological literature follow three directions of research: the description of pleistocene glacial and pleistocene-holocene periglacial landforms in the carpathians; the direct analysis of climate?s role in landform development; the integration of separate works and findings in a synthetic morphodynamic system applic...

Semiarid Mediterranean mountains are in general very sensitive to global climate warming in terms of deglaciation and permafrost degradation. In the context of the PACE-Project (Permafrost and Climate in Europe) the aim of the undertaken research is to gain a better understanding of late Pleistocene and Holocene glacial and periglacial history of Sierra Nevada, the southernmost European range w...

Extensive parts of Arctic permafrost-dominated lowlands were affected by large-scale permafrost degradation, mainly through Holocene thermokarst activity. The effect of thermokarst is nowadays observed in most periglacial lowlands of the Arctic. Since permafrost degradation is a consequence as well as a significant factor of global climate change, it is necessary to develop efficient methods fo...

The mechanisms of sediment removal associated with the nivation process suite are underinvestigated, a situation that hinders development unified, coherent theory cryoplanation terrace formation. This study links sorted stripes—a type periglacial patterned ground frequently encountered on treads—to active hydrologic networks capable transporting large quantities fine sediments hillslopes. Tradi...

Present morphology of the Mt. Wellington summit area can be interpreted in terms of a system of cryoplanation, which operated during the Pleistocene, but bas now ceased. This involved the rapid frost shattering of exposed dolerite and the removal of this and previously weathered material by mass movement over slopes as low as 30 • Periglacial processes of land reduction were probably widespread...

Introduction: In recent work [1-3] we used all relevant HiRISE (High Resolution Imaging Science Experiment), MOC (Mars Orbiter Camera), THEMIS (Thermal Emission Imaging System) and CTX (Context Camera) images in mid Utopia Planitia (UP; ~3060 0 N; Fig. 1) to map flat-floored and scalloped depressions, small-sized (~150m) polygonal patternedground and polygon-junction/trough pits (Fig. 2a). On ...
