Colorado National Monument, Colorado. Window Rock, a window eroded along a
vertical joint near the top of the Wingate Sandstone, viewed from Canyon Rim
Trail. The fenced overlook on the Kayenta Formation to the left of the window
keeps people from crossing the joint above the window, for someday the monolith
on the right will fall as did Fallen Rock (photo lsw00126). Light-colored Roan
Cliffs of the Green River Formation can be seen beyond Book Cliffs. 1976.
