This is Ribbon Falls, a half-mile or so side trip off the North Kaibab Trail up 5.8 miles above Phantom Ranch. It is a wonderful place to cool off and replenish your water supply. Carefully walk behind the falls and take a picture looking out through the falling water.
This is the creek at Cottonwood Campground, 6.9 miles above Phantom Ranch and 6.9 miles down from the North Rim. A rainstorm has made the creek "run red" as the NPS Ranger called it, as soil from the redrock area is carried all the way down to the Colorado River (which is Spanish for "red river" but now looks more green because Glen Canyon Dam traps the red soil, preventing it from making the trip down the Colorado.)
Ninety percent of the Grand Canyon's moisture falls on the North Rim and most percolates into and 3400 feet through the soil. Roaring Springs (5 trail miles below the North Rim) is where all the rainfall and snowmelt gush out of the cliff after hitting an impermeable layer of rock. A pumphouse located here pumps some of the water back to the North Rim for use at the facilities located there. The rest is piped 10 miles down to the Colorado River, where the piping crosses under the silver bridge and flows up to Indian Gardens umpumped (force of gravity and reduced diameter pipes allow this.) A pumphouse then sends the water up to large storage tanks on the South Rim.
This is a view of the Redwall Bridge, looking down from the North Kaibab
Trail. The bridge is dead center and crosses a deep depression, eliminating
an otherwise troublesome loss and regain of altitude.
This is near the top of the North Kaibab Trail looking down through the narrow canyon opening. As you approach the North Rim, the vegetation turns into lush conifer forest, quite a contrast from the lower areas of the canyon and also quite different from the scrubby forests of the South Rim which is at a lower elevation.
