Grey’s party began their trip near Flagstaff and traveled towards Tsegi Canyon, passing the Red Lake Trading Post and the Little Colorado River. At Tsegi canyon, they took a detour to view the Betatakin cliff dwelling ruins, and then made their way East towards Kayenta Trading post, where they stayed for a few days to rest their horses and rearrange their supplies. From Kayenta, John Wetherill and few Paiute men guided the party towards Rainbow Bridge heading Northeast above Navajo Mountain, riding over the glass mountains and finally reaching Rainbow Bridge.
