Grand Canyon National Park
Located
entirely in Arizona, the Colorado River has cut a canyon that is near 280
miles long. Being 18 miles wide and and 1 mile deep in some places,
the canyon is one of the most spectacular examples of erosion anywhere
in the world. The Grand Canyon is unmatched in the incomparable vistas
it offers to visitors and is a World Heritage Site. The Grand Canyon
Park entrance is 297 miles from Aztec. |
