A new study published in Science supports the theory that an ancient lake overflow in the Bidahochi basin triggered the Colorado River to carve the Grand Canyon.

The theory proposes the lake reached a tipping point, spilling over elevated terrain like the Kaibab Arch and forcing water to carve a new route.
