Physical Description
Switzerland extends between the parallels 45°49'05 and 47°48'30 lat. and the meridians 5° 57'23 and 10°29'31 long. It forms an irregular quadrilateral, of which the greatest length from east to west is 350 kilometres (220 mi), and the greatest breadth from north to south is nearly 220 kilometres (140 mi). Switzerland is a landlocked country, the closest coastline being at the Gulf of Genoa, 160 km south of Chiasso. Its political boundaries often do not coincide with those of nature. The entire canton of Ticino is south of the Alps, as are the valleys of Simplon (Valais), Mesocco, Bregaglia, Poschiavo and Müstair (all in Graubünden); the whole canton of Schaffhausen and part of that of Basel are north of the Rhine, while a large part of Graubünden lies to the east of the Rhine basin, and Porrentruy is far down on the western slope of the Jura. Putting these exceptional cases aside, the physical geography of Switzerland may thus be described:
- On the south runs the main chain of the Alps which is joined, at Mont Dolent near Martigny, by the lower ranges that rise south of Lake Geneva, and which continues partly Swiss till close to Piz Lad on the east.
- To the north of this main chain there is another great range of mountains (wholly Swiss) only slightly inferior in extent and height, which starts from the hills known as the Jorat range above Lausanne, and culminates in the great snowy summits of the Bernese Alps and of the Tödi group, before trending to the north near Chur, and, after rising once more in the Säntis group, dies away on the southern shore of Lake Constance.
- The Swiss portion of the main chain of the Alps and the great northern outlier run parallel to each other from Martigny to near Chur, while for a short distance they actually unite near Pizzo Rotondo (west of the St Gotthard Pass), parting again near the Oberalp Pass (east of the St Gotthard). Between these two great snowclad ranges flow two of the mightiest European rivers, the Rhone towards the west and the Rhine towards the east, their headwaters being only separated by the tangled mountain mass between Pizzo Rotondo and the Oberalp Pass, which sends the Reuss towards the north and the Ticino towards the south.
- To the north of the great northern outlier rises the Jura range, a huge spur of the Alps (with which it is connected by the Jorat range), while between the northern outlier and the Jura extends what may be called the plains or plateau of Switzerland, consisting all but wholly of the undulating valley of the Aar (below Thun) with its numerous affluents. To that river valley, the valley of the Thur (a direct affluent of the Rhine), that lies between the Aar basin and the Rhine basin (Lake Constance) must be added.
Putting aside the valleys of the Ticino and Inn, Switzerland may thus be described as consisting of three great river valleys (Rhone, Rhine and Aar) with the smaller one of the Thur, which all lie to the north of the main chain of the Alps and include the region between the Alps and the Jura. If matters are examined more carefully, it can be noted that the Rhone and Rhine valleys are shut off from that of the Aar (and of the Thur) by the great northern outlier of the Alps, which consists of the Bernese and Glarus Alps. Two wide and undulating valleys (Aar and Thur) and two deeply cut trenches (Rhone and Rhine) thus lie on the northern slope of the Alps, to the north and south respectively of the great northern outlier of the Alps. The main chain of the Alps rises in Swiss territory to the height of 4,634 metres (15,203 ft) in the loftiest summit or Dufourspitze (wholly Swiss) of Monte Rosa, though the Dom (4,545 metres (14,911 ft)), in the Mischabel range, is the highest mountain mass which is entirely within Switzerland. The great northern outlier attains a height of 4,274 metres (14,022 ft) in the Finsteraarhorn, while the lowest level (193 metres (633 ft)) within the Confederation, is on Lake Maggiore (on the course of the Ticino). The highest permanently inhabited village in Switzerland is Juf (2,126 metres (6,975 ft)) at the head of the Avers valley (a tributary of the Rhine), while the lowest is Ascona (196 metres (643 ft)), on Lake Maggiore.

Famous quotes containing the words physical and/or description:
“Theory may be deliberate, as in a chapter on chemistry, or it may be second nature, as in the immemorial doctrine of ordinary enduring middle-sized physical objects.”
—Willard Van Orman Quine (b. 1908)
“I was here first introduced to Joe.... He was a good-looking Indian, twenty-four years old, apparently of unmixed blood, short and stout, with a broad face and reddish complexion, and eyes, methinks, narrower and more turned up at the outer corners than ours, answering to the description of his race. Besides his underclothing, he wore a red flannel shirt, woolen pants, and a black Kossuth hat, the ordinary dress of the lumberman, and, to a considerable extent, of the Penobscot Indian.”
—Henry David Thoreau (1817–1862)
