Phantom Ranch Tour - upstream along the Colorado River in Inner Gorge

View looking upstream along the Colorado River in Inner Gorge from the Bright Angel Trail near Phantom Ranch. The Bright Angel Trail footbridge is in the foreground and the Kaibab Trail footbridge is in the distance. Phantom Ranch is on the left in Bright Angel Canyon (near the cottonwood trees). This image taken in early morning highlights the character of the Precambrian-age gneiss and granitic rocks (pink) and the biotite schist (dark gray). These types of rocks are the major components of the Vishnu Basement Rocks. Snow-capped Zoroaster Temple is in the distance; Sumner Butte (on the left) is about 1.5 miles northeast of Phantom Ranch.
