A large chunk of "older" consolidated gravel (about 12 feet tall and
4 feet wide) is imbedded sideways in "younger" consolidated gravel. The
younger gravel has bedding that is basically parallel to the modern stream
gradient. Also note the layers of Noonday Dolomite to the left of the
human (for scale). The ancient alluvial sediments fill an older stream
channel that is different than the cut of the modern stream in this part
of the canyon. |
