Unkar Delta:
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 (AD 850 to AD 1200).
More than 2500 archeological sites have been found in Grand Canyon. They are vulnerable and irreplaceable. Laws protecting archeological sites and artifacts are strictly enforced.
Archeologists suspect that Unkar Delta was occupied primarily in winter, with many occupants moving to cooler sites on the North Rim in summer. |
