Arches National Park, USA

The Arches National park, as it is generally clear from the name, became famous thanks to the whimsical arched constructions. There is the unbelievable amount of them in a park.

All of them are various by size, by appearance and by location – some of them are located not far from a road, and some are tucked away deeply into the valleys. Paths different on distance and complications lead to them, including quite wild and unexplored ones.

A national park is on the top of evaporite underground layer or rock salt, which is a principal reason of forming of arches, turrets, proportional cliffs and washed out monoliths in this area. For millions of years this salt was covered by alluvial breeds and was exposed to suffer from erosion by raising of unkompagrit in the northeast.

As underground motions of salt began to be responsible for forming of landscape, erosion washed off the young layers of mountain breeds from the surface except separate bits and pieces, the structures of which are visible today in a park. The arches consist of the salmon Entrada Sandstone and the color of the buff prevails in Navajo Sandstone.

These wonderful natural constructions look like the layers of cake in a course of time running into water, which leaks into the superficial cracks and folds of layers. Appearing ice broadens and begins to press on a breed from within, causing destruction, so that free particles after are simply blown away.

Besides the arches, there are some “windows” in a park. Many people do not know what they differ in. Honestly, they have small differences, and, generally, not fundamentally, as you will name a flourish is an arch or window. However, for taking interest, an “arch” is a hole that must be not less meter in length in any direction. Some differ “window” from an arch is that it is ordinary the “gap” in a rocky wall, located highly above earth. Some arches are named windows too, if there is a good review opening on a vicinity through them. There is another alike structure called “natural bridge”. What is the difference? While windows and arches ensue erosion under the act of winds and rain-water, the bridges are a job of running waters that sharpen shallow clefts performance. Here is it.

The Arches National park is located in east part of the state Utah, not far from Moab city. There are 2000 natural arches of sandstone, including the known worldwide “Elegant arch”, and many other various geological natural resources and structures on the park’s territory.
