[1] Mile 14.5 – Sheer Wall Rapid (2) Mile 17.1 – House Rock Rapid (7) – The first major rapid in Marble Canyon. A large hole on the left side of the river forms at most water levels, necessitating a right run. Mile 17.7 – Redneck Rapid (3) Mile 20.7 – North Canyon Rapid (5) (beginning of the "Roaring 20's") Mile 21.4 – 21 Mile Rapid (5)
Rio Grande Gorge Bridge. Geologically, the Rio Grande Gorge is a canyon, [1] carved out by erosion over the last several million years. [2] The Rio Grande Gorge and its river follow a topographical low within the larger Rio Grande Rift; a mixture of volcanic activity, shifting tectonic plates, and erosion of layers of gravels and lava yielded the recognizable narrow, deep gorge visible today.

The Vikos Gorge, with a length of 32 km (20 mi), walls that range from 120–1,350 m (390–4,400 ft) deep, and a width ranging from 2,500 m (8,202 ft) to just a few meters at its narrowest part, is listed by the Guinness Book of Records as the deepest canyon in the world in proportion to its width, [2] [5] though some gorge lobbyists contest ...
