Numerous islands along the 2.7-kilometre (1.7 mi) long edge divide the falls into about 275 separate waterfalls and cataracts, varying between 60 metres (200 ft) and 82 metres (269 ft) high. About half of the river’s flow falls into a long and narrow chasm called the Devil’s Throat (Garganta del Diablo in Spanish or Garganta do Diabo in Portuguese). The Devil’s Throat is U-shaped, 82 meter (270 ft.) high, 150-meter (152 ft.) wide, and 700-meter (2296 ft.) long.
