Answer 3

It's the Colorado river, but it's also due to plate tectonics. Two things happened in the SW USA: 1. The Colorado Plateau (northern AZ, southeastern UT, western CO, and northwestern NM) rose, and the Gulf of California opened, creating a depression for the Colorado River to flow into. The large elevation difference created a steep gradient, causing the river to cut deeply and quickly into the bedrock.
