Yesterday, I told you how sandstone fins are the first step in the long process of creating an arch. Today, I am showing you the photo of a fin that did eventually form into an arch.
There is no one answer as to how long an arch can take to form…usually it takes thousands of years. It is estimated that the famous Delicate Arch, also found in The Arches National Park, took around 100,000 years to form. There is another arch in the park that was not an arch in 1940…but some unexpected events helped it form into a full blown arch in the last 70 years.
The arch you see in this image will eventually disappear. The forces of nature are forever at work. Eventually, parts of the arch will start falling away and the weight of the remaining rock will eventually cause the arch to collapse. About a year ago, the well-known Wall Arch in the Devil’s garden collapsed completely. But, don’t worry…new ones are always forming.
