 An Unusual Arch

   February 08, 2021

    ARCH

   Photographer:  Stan Wagon
   Summary Author:  Stan Wagon

   There are many different  types of geologic arch. Shown above is a
    waterfall arch, which directly contradicts the  classic arch
   definition of a curved structure that gains strength from the curve.
   Uniquely, this one consists of a straight row of discrete cubic forms
   and has had enough strength to stand for perhaps ten thousand years.
   This particular cobblestone structure is made of  Salt Wash
   Sandstone, part of the  Morrison formation and is located in
    Arches National Park. Photo taken April 22, 2018.
