Le bilan est faiblement positif. Annuellement, les mesures effectuées et les estimations donnent un bilan excédentaire de 12gt par an. Cet état positif du bilan contraste avec les signes géomorphologiques provenant du Sud des PrinceCharles

Malgré la dépression générale due au poids de la calotte glaciaire, par endroits, le soulèvement local s'est produit en même temps que la glaciation. Les preuves d'un soulèvement dans trois endroits sont développées: dans les Monts du PrinceCharles
of accumulations, it can be supposed that an intensive uplifting of Ore Mountains (Krušné hory) went on in the Middle Pleistocene, beginning in the Riss. Holocene processes seem to be less intensive. - (MS)

Two types of landforms attributed to the geomorphological effects of long-lasting snow accumulations, snowpatch hollows and pronival ramparts, were studied in the Krkonoše Mountains, Czech Republic. Factors influencing the distribution

This paper presents Schmidt hammer (SH) measurements on intact and prepared surfaces in the Jizerské hory Mountains, Czech Republic. SH R-values were collected from granite outcrop surfaces and from vertical profiles below rock surface. The main

Use of 10Be exposure ages and Schmidt hammer data for correlation of moraines in the Krkonoše Mountains, Poland/Czech Republic
for moraines indicate relatively short period of glacier accumulation. A comparison of the obtained chronological data with timing of mountain glaciation in the nearby Úpa Valley is used to propose the first correlative model of Late Quaternary glaciation
in the eastern part of the Krkonoše Mountains. The correlation implies that the lowermost preserved moraines originated during the local maximum of the last glaciation whereas recessional moraines were deposited until the Lateglacial period. A subsequent melting

As part of a reconnaissance study in Prince Olav Harbour (POH), South Georgia, the AA. measured the size of lichens (Rhizocarpon) on ice-free moraine ridges around 2 small mountain cirques. Their aims were twofold : first, to provide age estimates
