Érosion glaciaire du calcaire, oui ou non ? Les points positifs et négatifs de l'interprétation géotectonique de l'évolution géomorphologique de la Vallée des lacs du Triglav
The paper deals with the problem of glacial erosion in the carbonate rocks in parts of the Julian Alps. The paper is critical to tectonic interpretation of geomorphological evolution of the TriglavLakesValley which denies the role of glacial
erosion and of other morphogenetic agents during the Pleistocene. The glacial and non-glacial morphogenetic factors cannot be completely neglected and the geomorphological evolution of the valley differs with such exclusively tectonic explanation.

The article deals with the problem of appropriate role of relief and geomorphology in nature interpretation in the area and on the nature trails in the Triglav National Park. The six most famous nature trails and areas of interest do not prove

of protected areas in the area of Upper Sava Valley. The survey was focused on the reasons of visit, the proposals and wishes of visitors in the connection with the future Triglav National Park development. - (L'A.).
Protected areas offer natural and other qualities to visitors. At the same time, these areas are co-formed by tourism and recreation. In the case of Triglav National Park, we researched the compatibility of protection and tourism function

The purpose of this paper is to document the outburst origin of the Grand Valley and to explore the implications of these events upon interpretations of the timing and processes of lake-leved changes in glacial Lake Chicago.
Lake Manly(?) shorelines in the Eastern Mojave Desert, California
California ; Desert ; Lake level ; Palaeo-environment ; Palaeolake ; Pleistocene ; Pluvial ; Quaternary ; Tectonics ; United States of America
During pluvial periods of the late Quaternary, Death Valley was occupied by a lake, called Lake Manly. The most prominent shoreline of this lake is that of the Blackwelder stand, 90 m above sea level. The Mesquite Spring and Salt Spring Hills
shorelines were probably formed by the Blackwelder stand and subsequently displaced , tectonically, due to transpression in the northeastern Mojave Desert and NW-SE extension across Death Valley. This tectonic regime would result in subsidence of Death Valley
Use of soil chronosequences for testing the existence of high-water-level lakes in the McMurdo Dry Valleys, Antarctica

The AA. utilize field observations and data collected from 190 pedons from Wright and Taylor Valleys to search for evidence of high-water-level lakes proposed to have existed during the last Glacial Maximum and early Holocene in the McMurdo Dry
Valleys. The results cast doubt as to whether high-level lakes existed in the McMurdo Dry Valley as recently as the early Holocene. An alternative explanation is that the former lakes had no effects on soils other than depositing deltas with cyanobacteria

Evidence from the Neva River valley, Russia, of the Holocene history of Lake Ladoga

Two new sections have been discovered in the River Neva Valley, which connects Lake Ladoga with the Gulf of Finland of the Baltic Sea. The radiocarbon dates, as well as pollen and diatom analyses of the new sections, support previous ideas
that the connection between Lake Ladoga and the Gulf of Finland opened as a result of the last great rise of the lake level, which was named the ladoga transgression. The evidence from the River Neva also confirms that there was no connection in this area between
the Baltic Sea and lake Ladoga at the time of the Ancylus Lake, because of the existence of uninterrupted peat deposition from Preboreal time.
The Mladotice Lake, western Czechia: the unique genesis and evolution of the lake basin

The Mladotice Lake is a lake of unique genetic type in Czechia. In May 1872 a landslide as a result an extreme rainfall event occurred in western Czechia, blocking the Mladotický stream valley and creating the Mladotice Lake. Our analysis

Previous studies of Adrian Pass concluded that it was an abandoned channel of the Walker River. The evidence presented in this study suggests that Adrian Pass was formed by overflow of Lake Lahontan, the second-largest Great Basin Quaternary lake
, from the lower Walker River Basin to the Carson Desert Basin. Walker River occupancy of Adrian Pass during post-Lake Lahontan time was relatively brief. - (SLD)

The AA. use new exposures in the West Branch Susquehanna River (WBSR) valley and magnetostratigraphy to reconstruct depositional environments in Glacial Lake Lesley, constrain the age of Glacial Lake Lesley, and constrain the maximum extent
of Glacial Lake Lesley. To achieve these objectives, detailed stratigraphic sections were described at McElhattan and Linden. The AA. use paleomagnetism as an age correlation tool in the WBSR valley to correlate contemporeanous glaciofluvial and proglacial
