It is amazing to think about how this canyon was formed. We attended a ranger talk, and he simplified the canyon's formation as D.U.D.E.:
D= Deposition (water from the ancestral Pacific Ocean shore moving back and forth leaving deposition from many kinds of rocks)
U= Uplift (volcanic eruption and plate tectonics pushing up the mountains)
D= Downcut (the Colorado River flowing through the area, carving away the land, cutting deeper and deeper)
E= Erosion (earthquakes, snow, ice, and rain continue to weaken the rock and carry fragments away)

Grand Canyon is definitely worth the trip. We studied earth science this year, so it was particularly pertinent to us. There is so much to get out of a visit here - geology, history, nature, exercise, and most importantly God's creation.
