Grand Canyon

Grand Canyon er en kløft, som er opstået ved erosion, idet Coloradofloden har gravet sig ned i bjerggrunden gennem 5 - 6 millioner år og dannet den. Den er 446 km lang, op til 29 km bred og ca. 1,86 km. dyb med meget stejle skrænter, hvilket gør den til en af verdens største kløfter. Den er beliggende i Coconino County i det nordlige Arizona, USA. Dele af Grand Canyon ligger i Grand Canyon National Park, en af de første nationalparker i USA. Den løber endvidere gennem Kaibab National Forest, Hualapai indianernes reservat, Havasupai indianernes reservat og Navajo Nation. Grand Canyons nationalpark har siden 1979 været med i Unescos liste over verdensarv. Kløften består af mange gamle bjergarter, hvoraf den yngste (og øverste) består af kalksten Under kalkstenslaget findes fleer ældre bjergarter. I klipperne findes mange forskellige fossiler. Dens nuværende form er et resultat af et tektonisk løft af hele plateauet, som startede for ca. 65 millioner år siden og var medvirkende til, at flodens strømning blev øget, således at det blev muligt for vandmasserne at skære sig gennem klippeformationerne. Flodens bearbejdning af landskabet betyder, at ca. to milliarder års geologiske historie er blevet afsløret, mens floden har banet sig vej gennem klippelagene.

    Beautiful is not a good enough word to describe this lovely place. Worth taking the time to visit. I’ve visited 5 times and it still is breathtaking and never looks the same. Highly recommend.

  • There are no words to describe the Grand Canyon, it’s a must see and the photos speak for themselves! These photos were taken on an iPhone 12 Pro and I keep thinking they look like a wallpaper from a computer! The park was so clean and beautiful!

  • One the most beautiful places , I ever visited. Definitely recommend to visit and explore this wonder. Miles and miles of gorgeous landscapes. Photos don’t make justice to this beauty. Also, the national park is clean and personnel is very friendly. I would give the park more stars but 5 is the max

  • Your first time seeing the Grand Canyon will take your breath away. There are no words or pictures that can explain just how vast and beautiful it is. At every stop is a new view and it is more breathtaking than the last. You could spend days in the park at never see the same sight twice. Because it is a lot of walking if your older or need accommodations be sure to take that into account. Children should be watched closely because a lot of places do not have railing. Pets are allowed so long as they are leashed. Weather was just right this time of year. [August] I’ll return one day. And soon.

  • This is perhaps one of the most beautiful places in the world. It was my family's first time visiting the Grand Canyon. I'm not really sure a photo gives it justice, such a beautiful place is truly amazing. But it's a must visit to experience this amazing place, the views will take your breath away. I will come again to explore this wonderful place.

    I've had the distinct pleasure of visiting not once, but twice. Each visit was simply amazing, and for different reasons. My first visit (as pictured here) was in spring of 2008. My Dad and I visited together as a father-daughter trip. We experienced all four seasons within one day -- snow, fog, beautiful sunrise, overcast skies, and the purest sunset you can imagine. It was unlike anything I had ever experienced before. My second visit was in August 2014 with my husband. This visit was hot & dry, but equally beautiful! It was amazing to see my husband's reaction to the Grand Canyon for the first time. If you've never been to the Grand Canyon, it's a must-see destination that pictures can't fully capture.

  • This is a beautiful national park that highlights the natural beauty of the canyon but also provides a great deal of context as you hike, pointing out the billions of years of rocks and the culture of indigenous people who've lived in the region for centuries. I took many photos, but none really capture the sheer size.
