Salzburg is not, however, merely the name of a town, but also of a province or "department" of Austria, to which empire it is the last added territory.[15] Lying between Tyrol (of which by many it is erroneously supposed to form a part) and the Salzkammergut or the lake region of Upper Austria, which commences in the near neighbourhood of the city, it was an independent episcopal principality until after the fall of Napoleon, not having been incorporated with the Austro-Hungarian Empire until the year 1816. [Sidenote: THE SALZACH VALLEY] The province consists chiefly of the mountainous district of the Salzach and its numerous tributaries, which wend their way from their sources amid the glaciers and snow-fields of the great peaks of the Hohen Tauern and lesser ranges to the plain where the Salzach itself ultimately flows into the Inn. It is the great Hohen Tauern range with its gigantic snow-crowned peaks of the Gross Glockner, 12,460 feet; Wiesbachhorn, 11,710 feet; and Gross Venediger, 12,010 feet; Hohe Furlegg, 10,750 feet; Habachkopf, 9945 feet; and many other almost equally stupendous heights, which forms the southern boundary of the ancient Principality. The whole range is one of impressive grandeur, and possesses a picturesque beauty upon its lower slopes unrivalled by any other Alpine district. The foot of the Hohen Tauern is almost invariably clad with pine forests, which melt away into the higher slopes where blooms the bright pink "alpen rosen," whilst yet higher, and just below the line of perpetual snow, on rocky ledges and on slopes of coarse grass appear the silver-white, star-like flowers of the edelweiss. Above this zone of fresh green patches amid the grey and weather-stained rocks one passes into that exhilarating region of eternal snow and ice where dwells also eternal silence unbroken by the sound of birds, the hum of insects, or murmur of other living things. Not only is the Hohen Tauern the region of Alpine giants, vast glaciers, and untrodden snow-fields, but as a natural consequence of these things it is that of many rushing torrents, stupendous waterfalls, and tinkling streamlets, all of which contribute to make the province it borders one of the best-watered in the Austro-Hungarian Empire. Upwards of half a score of large streams flow into the Salzach; whilst of fertile valleys there are so many that to number them is difficult. Most are beautiful in the extreme; many are almost unknown to the ordinary tourist, who usually sticks to the well-worn paths and more frequented highways. In the famous Krimml Falls the Province of Salzburg possesses by common consent the finest waterfalls in the German Alps. They issue from the vast Krimml Glacier and descend over the edge of a pine-clad precipice in a cloud of drifting spray into the valley beneath, a distance of nearly 1500 feet, in three stupendous leaps, the highest fall in two leaps from a height of more than 450 feet.
