The Colorado River
Probably Los Angeles Air Force Base.
The Colorado river is at the bottom of the grand canyon.Over millions of years,it has carved the biggest gorge in the world.
They are roots of extremely old mountains that had eroded significantly before being covered with repeated layers of sedimentation from a now extinct inland sea.
no, it was caused by long periods of contact with the river at its base that eroded it to look the way it does now.
The oldest fossils in the Grand Canyon are found in the layers of sedimentary rock near the bottom of the canyon, dating back around 1.2 billion years ago. These fossils provide insights into early life forms and the geological history of the region.
