The Dolomites may be divided into the following groups, running from east to west.[20] (1) The Sextner Dolomites, the most important summits amongst which are the Drei Schuster Spitz, 10,375 feet, which is ascended generally from the Fischelein Boden; the Elferkofel, 10,220 feet; the Zwölferkofel, 10,150 feet; Oberbacher Spitz, 8700 feet, and the Drei Zinnen, 7897 feet, two absolutely bare peaks of sulphurous limestone, streaked with pale orange, rising grandly and boldly from behind the Monte Piana plateau like two huge scored and fissured fingers of a Titanic hand. (2) The Ampezzaner Dolomites, with Monte Cristallo, 10,495 feet, with its many peaks veiled by snows, glassing itself in the agate green waters of the lovely pine-environed Dürren See. Monte Antelao, 10,710 feet; the three Tofanas, ranging in height from 8565 feet to 10,635 feet; and the Sorapis, 10,520 feet. (3) The Agordinischen Dolomites, with the Nuvolau, 8685 feet; Monte Pelmo, 10,395 feet; and Monte Civetta, 10,565 feet, whose western face from Caprile was unascended till as recently as 1895, when Messrs. Raynor and Phillimore, with two Ampezzo guides, made the ascent. (4) The Grödener Dolomites, which embrace the beautiful Rosengarten, the Schlern, 8415 feet; the Sella-group, including the Sellajoch, 7275 feet; Rodella, 8155 feet, and other lesser peaks; and the Geislerspitzen, with its highest peak, Sas Rigais, 9930 feet. (5) The Fassaner Dolomites, consisting of the groups of the Latemar, 9166 feet; the Marmolada, the highest of all the Dolomites, a huge group with several peaks, including the Puntadi Penia, 11,020 feet; the Marmolada di Rocco, 10,820 feet, and other magnificent and lofty summits; and the Pala Group, including the Cimone Della Pala, 10,450 feet, the Pala Di San Martino, 9830 feet, and the Pala Della Madonna, 8336 feet. There are numberless interesting and picturesque excursions to be made in this charming region of the Dolomites, but the space at our disposal will only permit of the mention of a few of the most accessible, interesting, or picturesque.
