“He doesn’t need any money; all he needs is his rucksack with those little plastic bags of dried food and a good pair of shoes and off he goes and enjoys the privileges of a millionaire in surroundings like this.” - Jack Kerouac
Looking west down the canyon you can see the Colorado River in this shot. You can also clearly see the varied levels of strata that allow the different rates of erosion. The hardest rock remains longest, while the softer rock washes away more slowly.

In the early days of was was to be the Grand Canyon, the river was at rim level. As material washed away over millions of years the canyon got deeper and deeper. Now the river is running through tough igneous rock and the erosion has slowed or stopped.

The sides of the canyon are still eroding, but now at a much slower rate as only rain, snow, and wind are doing the work.
