View from the North Rim
Below the rim lies an intricate landscape of erosional landforms, shaped by water from rain and snow but untouched by the Colorado River. This on-going process of weathering and erosion is also responsible for the network of tributary canyons that feed into the Colorado River. The river itself is invisible from this vantage.
Geologists estimate that it has taken less than 5 or 6 million years to carve the canyon and create the landscape you see before you. |
