The base level and course of the Colorado River (or its ancestral equivalent) changed {{nowrap|5.3M years ago}} when the [[Gulf of California]] opened and lowered the river's [[base level]] (its lowest point). This increased the rate of erosion and cut nearly all of the Grand Canyon's current depth by {{nowrap|1.2M years ago}}. The terraced walls of the canyon were created by differential erosion.<ref>{{cite web|url=http://academic.brooklyn.cuny.edu/geology/leveson/core/graphics/nyc_mins2/hyp_test_diff_erode.html|title=The Hypothesis of Differential Erosion|first=David|last=Leveson|accessdate=2010-10-22}}</ref>

Between 100,000 and 3M years ago, [[Geology of the Grand Canyon area#Volcanic activity dams the new canyon|volcanic]] activity deposited [[volcanic ash|ash]] and [[lava]] over the area which at times completely obstructed the river. These volcanic rocks are the youngest in the canyon.
