According to scientists the southern part of the fissure is more recent and was formed after the monsoons in 2016.
In Arizona geologists took a three-kilometer crack.
Video recorded by a drone and published on the Youtube channel the Daily Mail.
It is noted that the fissure was formed in the period from March 2013 to December 2014 and in the same year greatly increased in size.
The real reason is not established, but it is likely that the crack occurred due to draining of underground water channels.
