Description :
The 10Be exposure method was applied to 21 samples of crystalline rocks from cirques, roches moutonnées, tors and glacial sediments in two valleys of Giant Mts. in the Bohemian Massif : the Obři důl and the Labský důl. Geomorphological evidence combined with 10Be dating shows the occurence of glaciation. Permanent ice and firn fields were still present in the upper part of cirques and in plateaus up to around 3-4 thousand years ago. - (MS)
