. The earth and its inhabitants ... Geography. AUSTEIA-HUNGAEY. Fig. I.—The Gap between the Inn and the Adige, AND THE MaLSER HeIDE. MO 10 P )t i,r Geologically there obtains great variety. The central range, which is upon the M'hole of the greatest average height, is formed of crystalline rocks. Limestones prevail in the Northern Alps, whilst the Southern Alps, abruptly sinking down into the plains of Italy, exhibit a great diversity of geological formation. There are schists, sandstone, black and red por- phyry, limestone, and, above all, dolo- mites. The division into Rhaetian, Noric, Garnie, and Julian Alps origin- ated with the Romans, and is not a happy one, for in Austria, as in France and Switzerland, the Alps are divided naturally into a number of mountain masses, forming as many secondary mountain systems. Th e range of the Rhiitikon separates Vorarlberg from the Grisons, and ex- tends from the Rhine to the valley of the Inn. Five glaciers descend from it into the valley of the Montafon, and the summits in the south rival in height those lying within the Swiss frontier.* The principal mountain group of Austria, that of the Orteler (12,814 feet), is cut off from the other moun- tains of the Tyrol by the deep valley of the Adige, but a ridge, over which runs the road of the Stelvio (Stilfser Joch, 9,172 feet), joins it to Piz Umbrail (9,954 feet), in Switzerland. This group rises to the south of the central axis of the Alps. It culminates in a superb pyramid of dolomite, and glaciers creep down its slopes in all directions, that of Sulden carrying a larger quantity of rocks upon its sur- face than any other in the Alps.
