Above/featured: West-northwest from Mohave Point – 15 October 2018 (HL).
26 February 2019 marks the 100th birthday of the Grand Canyon National Park.
On 26 February 1919, U.S. Congress passed legislation “An Act to Establish the Grand Canyon National Park in the State of Arizona” which was signed by President Woodrow Wilson. With official designation, the national park encompasses over 1-million acres (almost 405-thousand hectares) and several thousand years of history of habitation in the area by indigenous peoples including the Havasupai, Hualapai, Hopi, Navajo, Paiute, and the Zuni who consider the Grand Canyon as their ancestral birthplace. UNESCO inscribed the Grand Canyon National Park as World Heritage Site in 1979.
The geology at the Grand Canyon, however, is much much older than 100 years. By geologic standards, the Grand Canyon itself is relatively “young” with the Colorado River carving into the rock about 5 to 6 million years ago. However, the Vishnu basement rock in the Grand Canyon is over 1.7 billion years old; “only” 38 percent as old as Earth’s oldest rocks at 4.5 billion years old. For a rough comparison, if a person celebrated their 50th birthday today for a total age of 18262.5 days, the equivalence of the basement rock forming occurred about 19 years ago, and erosion by the Colorado River taking shape only 24 days prior to the 50th birthday.
In October 2018 we spent three days exploring parts of the Grand Canyon National Park. After our drive from Flagstaff to Cliff Dwellers (via Cameron), we pushed forward to the North Rim and the winding scenic drive took us to Point Imperial and Cape Royal in time for the day’s final illumination. With a night spent at the beautifully serene Cliff Dwellers Lodge, we retraced our drive back to Cameron, then turning west to Desert View and parts of the eastern end of the South Rim. With our new ‘base’ established in Flagstaff, we drove the following day to the main entrance of the Grand Canyon National Park (via Valle and Tusayan), and we spent the day in the western and central parts of the South Rim. The 1126 km (700 mi)# we covered over the three days was 22 percent of the entire 5049 km (3138 mi) we accumulated through parts of New Mexico and Arizona.
- North Rim: Point Imperial, Cape Royal
- South Rim: Desert View
- South Rim: Navajo Point, Lipan Point
- South Rim: Hermit’s Rest, Mohave Point
- South Rim: Village along Rim Trail
Four of Mary Colter’s buildings on the South Rim (Desert View Watchtower, Hermit’s Rest, Hopi House, and Lookout Studio) have been inscribed since 1987 as U.S. National Historic Landmark properties in the National Register of Historic Places (reference number 87001436).
