where was the dirt from the grand canyon deposited
So to answer your question the rock that was eroded from the Grand Canyon lies in deposits near the Colorado River (rivers change course and you will find old river deposits to the sides of the current path) and in the Gulf of California, the ultimate destination of the Colorado River.issolved load is the elements that have been dissolved the same as you would dissolve salt into water, this material is typically not deposited until the river has reached the ocean and the water has slowed enough to allow the elements to precipitate out.
