Colorado River
Colorado river
Its name refers to the darkness of the river bed that has been lined with thick layers of decomposing vegetation.
it has more rocks because the river has lots of sediments ( pieces of broken rock ) to carry along the river flow. then the sediments pile up into layers and then for many years the layers will harden and turn into a rock. YOUR WELCOME :)
