UNKAR DELTA IN GRAND CANYON  

Did You Know?
In Grand Canyon, the broad, sandy expanse on the north bank of the Colorado River is Unkar Delta, composed of rock debris carried from the North Rim by Unkar Creek. Prehistoric Pueblo people occupied numerous sites on Unkar Delta and along Unkar Creek for about 350 years (A.D. 850 to A.D. 1200)
