Largest
canyons
The definition of “largest canyon” is imprecise, as a canyon can be large by its depth, length, or the total area of the canyon system. Also the inaccessibility of the major canyons in the Himalaya contributes to their not being regarded as candidates for the biggest canyon. The definition of “deepest canyon” is similarly imprecise, especially if one includes mountain canyons as well as canyons cut through relatively flat plateaus (which have a somewhat well-defined rim elevation).
Project
Description
The deepest canyon in the world is at the confluence of the Gilgit and Indus rivers, where the Karakoram Highway was constructed, the river flows at an elevation of about 1,000 m (3,300 ft) above sea level. To the South by 15 km, rising in one continuous sweep above the Indus, the largest such rise on the planet, is the summit of the world’s 9th-highest mountain, Nanga Parbat, 8,126 m (26,660 feet) high. Rising to the north, also visible from the bridge over the Gilgit, is the westernmost of the great Himalayan peaks, Rakaposhi, 7,788 m (25,550 ft) high.
