The Grand Canyon is an extraordinarily steep area. If you go from the river at
the bottom of the Canyon (36 05 35.38 N 113 14 43.70 W) straight north up
the canyon rim (the area that flattens out above the red layers of rock – 36 06
10.12 N 113 14 48.88 W), what is the gradient of the Grand Canyon? (Hint:
You can tilt the image, which will make the flat rim easier to see, by either
pressing down on the middle mouse wheel and moving the mouse forward and
backward or by clicking on the arrows above and below the eye in the upper
right hand portion of the window.)
