There are many nat­ur­al occur­rences that can bewil­der the trav­el­er. This is one of them. This lit­tle slice of per­fec­tion. See the uni­form slit between the flat faces of these two stand­ing stones? Al Naslaa is one of the most pho­to­genic pet­ro­glyphs in the area. Its nat­ur­al shape is a big mys­tery that no one has been able to solve yet. Make sure you embark on a hol­i­day to Sau­di Ara­bia to catch a sight of this nat­ur­al struc­ture.
