   Summary Author:  Stan Wagon

   The  slot canyon known as West Wahweap, in  Grand Staircase
   Escalante National Monument, Utah, has a side canyon called Blue
   Wonder. This name supposedly arises because the reflected sky creates
   blue tones in the depths of the generally white sandstone canyon walls.

   The  Entrada Sandstone forming the walls is very soft, and the rare
   rains that fall results in some interesting shapes. Note the diorama of
    sandstone stalagmites having  seemingly human forms (top photo).
   These  stalagmites may only last a few months before the elements
   (rain, wind, frost) break them down. The bottom photo shows an extended
   “finger” of one such fragile stalagmite. Top photo taken on April 18,
   2021; bottom photo taken on November 11, 2019.

   Photo details: Apple iPhone 11 Pro camera; 4.3 mm lens; 1/60-second
   exposure; f/1.8; ISO 125.
