Amongst all these high glens there is a remarkable absence of lakes and waterfalls; nor are there down in the lower valleys at the foot of the mountains, as one would naturally expect in a region so extensively glaciated, any sheets of water corresponding to the Swiss lakes.
SVANETIA, a mountainous district on the south slopes of the Caucasus, immediately underneath the loftiest glaciated peaks of the middle of the system.
The maturely dissected and recently glaciated uplands of New England are now somewhat depressed with respect to sea-level, so that the sea enters the valleys, forming bays and estuaries, while the interfiuve uplands and hills stand forth in headlands and islands.
The valley floors always join at accordant levels, as is the habit among normally subdued mountains; they thus contrast with glaciated mountains such as the Alps and the Canadian Rockies, where the laterals habitually open as hanging valleys in the side slope of the main valleys.
It is thus by sub-glacial aggradation that the prairies have been leyelled up to a smooth surface, in contrast to the higher and non-glaciated hilly country next south.
Thus local sheets or aprons of gravel and sand are spread more or less abundantly along the outer side of the morainic belts; and long trains of gravel and sands clog the valleys that lead southward from the glaciated to the non-glaciated area.
In this central region, however, it is only by way of exception that the cirques were so far enlarged by retrogressive glacial erosion as to sharpen the preglacial dome-like summits into acute peaks; and in no case did glacial action here extend down to the plains at the eastern base of the mountains; but the widened, trough-like glaciated valleys frequently descend to the level of the elevated intermont basins, where moraines were deployed forward on the basin floor.
C. Russell, have yielded evidence of past climatic changes second in importance only to those of the Pleistocene glaciated areas.
The land rises to 1,500 ft., is heavily glaciated, and in geological structure is similar to the mainland.
The region is made up in general of high ranges deeply glaciated, preserving some remnants of ancient glaciers, and having fine " Alpine " scenery, with many sharp peaks and ridges, U-shaped valleys, cirques, lakes and waterfalls.
It is full of huge glaciated blocks, and in different regions (Prieska chiefly) the underlying pavement is remarkably striated and shows that the ice was moving southward.
Wisconsin has more than 2500 lakes, mostly in the glaciated N.
The glaciated rocks of the glen are clothed with vegetation of peculiar luxuriance, flourishing in the mild climate which has given Glengarriff its high reputation as a health resort for those suffering from pulmonary complaints.
