As the name says: Arches National Park is the National Park with the arches. There are more arches in the western U.S.A. and all over the world, but here you will find numerous spectacular arches on a rather small area. Probably the highest concentration of arches you can find worldwide.
Arches are formed by wind erosion, especially in arid climates. But they are normally quite an exception, and here they are found in abundance. The reason is halo-tectonics, earth movements caused by the flowing of salt under high pressure. Below the red sandstones lies an underground evaporite layer or salt bed. The 1,000m thick layer of salt was deposited in the Paradox Basin 300Ma ago during the end of the Permian and the beginning of the Triassic. It was covered by debris eroded from the Uncompahgre Uplift to the northeast. During the Jurassic the Navajo Sandstone was deposited on land under desert conditions. At this time the super-continent Pangaea existed and its interior was mostly arid. The salt dome lifted the sandstone in the form of flat ridges, the sandstone got parallel cracks which were the starting point for further erosion. The result are sandstone ridges which are formed by wind, sand and frost.
Probably the most interesting hike is the Fiery Furnace hike. Fiery Furnace is a labyrinth of narrow passages between towering sandstone walls. From above it looks like a series of deep parallel cuts which are connected by transverse clefts at fault zones. Its quite easy to get lost in the labyrinth and GPS does not work well because of the surrounding sandstone. You can walk on your own and there are also ranger guided hikes, but the number of permits for both is strictly limited. If you have a ticket you must check in at the visitor center at least 1 hour in advance.
Another impressive hike is Devils Garden, which is located at the end of the road. Here you have to walk because you can not see the arches from the parking lot.The full trail is 12km long, but the Landscape Arch, Tunnel Arch, and Pine Tree Arch can be seen on the first 2km. Double O Arch, which is probably the most impressive arch here is löocated at the end of the trail.
