Boite (river)

The Boite (Cadorino dialect, Guóite) is a river of the Veneto region of northern Italy. Passing through the town of Cortina d'Ampezzo, it joins the Piave at Perarolo di Cadore. The principal valley, that of the Piave, runs parallel to the mountain chain which separates the province of Belluno from the basin of the Adige. The secondary valleys, which complete the river basin, are, in descending order and on the right bank, those of Visdende, Comelico Superiore, Auronzo, Boite and Zoldo, traversed, respectively, by the Silvella, or first branch of the Piave, the Padola, Ansiei, Boite, and Mae, which all flow into the main river in a rectangular direction.

The Boite, a tributary of the Piave, flows through the Dolomites in a north-south direction, passing through the Valle del Boite and town of Cortina d'Ampezzo. It also passes through the comunes of San Vito di Cadore, Borca di Cadore, Vodo di Cadore and Valle di Cadore. The river Boite flows for 45.07 kilometres (28.01 mi), and has a basin area of 395.9 square kilometres (152.9 sq mi). During its course, it receives numerous streams and mountain rivers, the largest of which is the stream from Monte Rite at Cibiana di Cadore. Its tributaries are, Fanes, Costeana, Felizon, Ursuline, Assola, Rite, Rudan, Vallesina Over the course of the Boite are also the reservoirs of Vodo and Valle di Cadore. Near Cortina, it is encircled by mountain ranges of Cristallo, Sorapiss, and Tofane, whose peaks are Tofana di Mezzo (3,244 m), Tofana di Dentro (3,238m), and Tofana di Rozes (3,225 m).

The Boite and Piave drainage system belongs to the complex Dolomite Alps geology sequence made up of sedimentary rocks intruded with pyroclastic. These are found to overlay the thrust zones of igneous and meta sedimentary late Paleozoic rocks. Local intrusion of many types of shallow Mesozoic and tertiary rocks are also noted. The high rise domes of the mountains, primarily belong to the Mesozoic age and basically consist of dolostone with exposures of limestone, marlstone, claystone, siltstone, sandstone, tuff and conglomerates.
