Among the great glaciers which stream from the peak the most noteworthy are those of Bossons and Taconnaz (northern slope) and of Brenva and Miage (southern slope).
But there are no perpetual snow-fields, no glaciers creep down these valleys, and no alpine hamlets ever appear to break the monotony.
Below Aosta also the Dora Baltea receives several considerable tributaries, which descend from the glaciers between Mont Blanc and Monte Rosa.
But the effect of its southern latitude is tempered by its peninsular character, bounded as it is on both sides by seas of considerable extent, as well as by the great range of the Alps with its snows and glaciers to the north.
Snow accumulating on the higher portions of the land, when compacted into ice and caused to flow downwards by gravity, gives rise, on account of its more coherent character, to continuous glaciers, which mould themselves to the slopes down which they are guided, different ice-streams converging to send forward a greater volume.
Most of the glaciers terminate at an altitude of 14,800-14,900 ft., but the small Cesar glacier, drained to the Hausberg valley, reaches to 14,450.
Beyond this point the Anglo-Russian Commission of 1895 demarcated a line to the snowfields and glaciers which overlook the Chinese border.
On the Swiss Alps it is one of the most prevalent and striking of the forest trees, its dark evergreen foliage often standing out in strong contrast to the snowy ridges and glaciers beyond.
The Aptera have perhaps the most extensive distribution of all animals, being found in Franz Josef Land and South Victoria Land, on the snows of Alpine glaciers, and in the depths of the most extensive caves.
They not only indicate the height of the land, but also enable us to compute the declivity of the mountain slopes; and if minor features of ground lying between two contours - such as ravines, as also rocky precipices and glaciers - are indicated, as is done on the Siegfried atlas of Switzerland, they fully meet the requirements of the scientific man, the engineer and the mountain-climber.
C. von Sonklar, in his map of the Hohe Tauern (r: 144,000; 1864) coloured plains and valleys green; mountain slopes in five shades of brown; glaciers blue or white.
They are printed in three colours, contours at intervals of 10 and 20 metres being in brown, incidental features (ravines, cliffs, glaciers) in black or blue.
The shores are so extensively indented with voes, or firths - the result partly of denudation and partly caused by glaciers - that no spot in Shetland is more than 3 m.
The presence of enormous glaciers in the Ice Age is attested by the moraines at the Atlantic end, and by other indications farther east.
The coast-line of Melville Bay (the northern part of the west coast) is to some degree an exception, though the fjords may here be somewhat filled with glaciers, and, for another example, it may be noted that Peary observed a marked contrast on the north coast.
In some parts the interior ice-covering extends down to the outer coast, while in other parts its margin is situated more inland, and the ice-bare coast-land is deeply intersected by fjords extending far into the interior, where they are blocked by enormous glaciers or " ice-currents " from the interior ice-covering which discharge masses of s"aefel's0° icebergs into them.
In the rapidly moving glaciers of the icefjords this striation is not distinctly visible, being evidently obliterated by the strong motion of the ice masses.
Here the ice converges into the valleys and moves with increasing velocity in the form of glaciers into the fjords, where they break off as icebergs.
In twenty-four hours, with which the glaciers of Greenland move into the sea, the margin of the inland ice and its glaciers was studied by several expeditions.
(Danish).3 It was, however, ascertained that there is a great difference between the velocities of the glaciers in winter and in summer.
There seem to be periodical oscillations in the extension of the glaciers and the inland ice similar to those that have been observed on the glaciers of the Alps and elsewhere.
This iron is considered by several of the first authorities"on the subject to be of meteoric origin,' but no evidence hitherto given seems to prove decisively that it cannot be telluric. That the nodules found were lying on gneissic rock, with no basaltic rocks in the neighbourhood, does not prove that the iron may not originate from basalt, for the nodules may have been transported by the glaciers, like other erratic blocks, and will stand erosion much longer than the basalt, which may long ago have disappeared.
Its early beginnings take their rise amidst a mighty mass of glaciers which cover the northern slopes of the watershed, separating them from the sources of the Gogra on the south; and there is evidence that two of its great southern tributaries, the Shorta Tsanpo (which joins about 150 m.
These trenches have for successive geological periods been the drainage valleys of immense lakes (probably also of glaciers) which formerly extended over the plateau or fiords of the seas which surrounded it.
It rises in the glaciers of the Tbdi range, and has cut out a deep bed which forms the Grossthal that comprises the greater portion of the canton of Glarus.
There are also many smaller lakes fed by the glaciers of the Sailughem (Achit-nor, 4650 ft., and Uryu-nor), and others scattered through the Ektagh Altai.
(1) The principal stream is considered to be that of the Hinter Rhine, which issues (7271 ft.) from the glaciers of the Rheinwaldhorn group, and then flows first N.E.
Forbes was also interested in geology, and published memoirs on the thermal springs of the Pyrenees, on the extinct volcanoes of the Vivarais (Ardeche), on the geology of the Cuchullin and Eildon hills, &c. In addition to about 150 scientific papers, he wrote Travels through the Alps of Savoy and Other Parts of the Pennine Chain, with Observations on the Phenomena of Glaciers (1843); Norway and its Glaciers (1853); Occasional Papers on the Theory of Glaciers (1859); A Tour of Mont Blanc and Monte Rosa (1855).
Over the whole state there is a layer of drift deposited by the glaciers which once covered this region.
The narrow strait Strdmmen separates Kvalii from the larger Seiland, whose snow-covered hills with several glaciers rise above 3500 ft., while an insular rampart of mountains, Sord, protects the strait and harbour from the open sea.
In the Dachstein group are found the most easterly glaciers of the Alps, of which the largest is the Karls-Eisfeld, nearly 22 m.
The Carpathians, which only in a few places attain an altitude of over 8000 ft., lack the bold peaks, the extensive snow-fields, the large glaciers, the high waterfalls and the numerous large lakes which are found in the Alps.
They are nowhere covered by perpetual snow, and glaciers do not exist, so that the Carpathians, even in their highest altitude, recall the middle region of the Alps, with which, however, they have many points in common as regards appearance, structure and flora.
It drains the tract between the Yamdok Tso and Tigu Lakes, and is fed by the glaciers of the Kulha Kangri and other great ranges.
There are no glaciers near its sources, although they must have existed there in geologically recent times, but masses of melting snow annually give rise to floods, which rush through the midst of the valley in a turbid red stream, frequently rendering the river impassable and cutting off the crazy brick bridges at Herat and Tirpul.
In the north, icebergs break off, as a rule, from the ends of the great glaciers of Greenland, and in the far south from the edge of the great Antarctic ice-barrier.
Its glaciers send down a thousand rills which combine to form the Pangani river.
Along the Ruwenzori range are glaciers and snowfields nearly 15 m.
North America is bathed in frigid waters around its broad northern shores; its mountains bear huge glaciers in the north-west; the outlying area of Greenland in the north-east is shrouded with ice; and in geologically recent times a vast ice-sheet has spread over its north-eastern third; while warm waters bring corals to its southern shores.
South America has warm waters and corals on the north-east, and cold waters and glaciers only on its narrowing southern end.
A district of considerable extent in the centre of the island is occupied by snowfields, whence glaciers descend east and west to the sea.
After the continental ice sheet entirely disappeared from the state, local valley glaciers lingered in the Adirondacks and the Catskills.
Apart from the fjords and lakes the chief beauties of the Alps are glaciers and waterfalls.
To the west of Aorangi glaciers crawl into the forest as low as 400 ft.
The Pleistocene system in the South Island includes glacial deposits, which prove a great extension of the New Zealand glaciers, especially along the western coast.
The glaciers must have reached the sea at Cascade Point in southern Westland.
Glaciers are common both in the N.
On its slope, which rises abruptly from the Bitterroot Basin, glaciers have cut canyons between high and often precipitous walls, and between these canyons are steep and rocky ridges having peaked or saw-toothed crest lines.
Deep and narrow canons are common, and, at higher levels, glaciers, carved out amphitheatres, or " cirques " and " U "-shaped troughs.
As the part east of the river was once covered by the ice-sheet, its hills have been lowered and its valleys filled through the attrition of glaciers until the surface has a gently undulating appearance.
