| description | <p>Whilst previous work has successfully reconstructed the evolution of temperatures in the region north of the Alps during the final phase of the Late Pleistocene, precipitation patterns still remain largely unknown. Recent studies have shown that reconstructing former glaciers in the mid-elevation mountain ranges in central Europe, calculating equilibrium line altitudes (ELAs), and using of empirical relationships between summer temperature and precipitation at the ELAs of modern glaciers could be a promising avenue to fill this gap. Since non-climatic factors probably had only a minor influence on glacier dynamics, the numerous ice-marginal landforms north-east of the highest summit of the Black Forest, Feldberg (1493 m a.s.l. (metres above sea level)), represent prime candidates for climate reconstruction. Since detailed geomorphological and chronological investigations must precede such a study, this work aims to re-examine these landforms with the aid of high-resolution remote sensing data and field mapping. This study allowed for the mapping of glacial landforms in unprecedented detail and for the selection of targets for future dating studies. The re-examination of the glacial record north-east of Feldberg largely confirmed existing studies, and only a few previously mapped ice-marginal landforms must be rejected. At the same time, however, this study identified numerous landforms at former ice-marginal positions that have not yet been described in the literature. These results underline once again that dating studies should always be based on detailed geomorphological mapping. Red-relief image maps (RRIMs) derived from digital elevation models (DEMs) proved to be an extremely helpful visualisation method for the identification of ice-marginal landforms. We therefore advocate for the more frequent use of these maps in glacio-geomorphological studies. Determination of the age of glacial landforms with the aid of cosmic-ray exposure (CRE) dating and luminescence methods will allow for the establishment of an integrated regional stratigraphical model. Once the stratigraphy is constructed, glacier, ELA, and precipitation reconstruction can be undertaken.</p> |
