Only accessible by foot or horseback, Grand Gulch is a tributary canyon where water eventually flows to the San Juan River, which then ultimately flows into the Colorado River and Lake Powell. Home to the Anasazi people between 700 and 2,000 years ago, the area is rife with artifacts, from dwelling structures to artwork—all in impressive condition thanks to the cautious and respectful treatment of those who visited before you. Baskets were among the earliest relics to be found and potsherds can still be discovered here, hidden in the right spots to protect them from the weather.
