Arches National Park, Utah
This stunning structure is Delicate Arch, the most famous of 2,000 stone arches scattered around Arches National Park in Utah. It is made up of Entrada Sandstone, the grains of which once formed a massive desert. They were cemented together by minerals, forming sandstone riddled with tiny holes. Over millennia, the rain seeped in and slowly dissolved the rock from the inside, forming these eye-catching sculptures. Most of the arches in the national park are formed from Entrada Sandstone and were once buried by other rock layers. They won't last forever, but over time, new shapes will emerge from the layers of rock below to replace them. Every year, close to 1.4 million people visit the park to see Delicate Arch and this slowly shifting landscape for themselves.
著名海拱门的末日 Last days of a famous sea arch
On Darwin Day, we visit Darwin's Arch, named for the famous English naturalist Charles Darwin who was born on this day in 1809. The last time the arch looked as it does in this image was May 17, 2021. That's when this sea arch collapsed due to natural erosion and became a pile of rubble between what is now two pillars. Some locals and scientists have renamed the rock formation the 'Pillars of Evolution,' a nod to Darwin's theory of evolution by natural selection.
Sea arches are found all over the world, often where cliffs meet the sea. They're formed as waves erode the underside of a rock, leaving the top. Darwin's Arch is located southeast of Darwin Island, part of the Galápagos Archipelago in the Pacific Ocean.
Art in the high desert
The desert doubles as an art studio this week at Arches National Park, as painters from all over congregate for the Red Rock Art Festival. This Moab-based event is a celebration of what the French call painting 'en plein air,' or painting outside. Sounds like a fabulous idea to us (and what a view!). The colorful landscape here at Arches National Park is home to the highest density of natural arches in the world—upwards of 2,000—as well as more pinnacles and dramatically balanced rocks. Combine that with the fiery sunsets, pinyon trees, and splashes of sage and yucca, and we’d say these artists are in for a treat. Lucky for them, October is a pleasant time to visit the harsh, desert landscape.
