Iridescent Pileus Cloud Over Barra Grande, Brazil

On the evening of December 5th, 2021, I observed this colorful
iridescence formed on a pileus cloud while walking by the beaches
of Barra Grande near Cajueiro da Praia, Brazil. This colorful cloud
was annex to a huge cumulus cloud. I was quite amazed by the vivid
and spectacular colors of this phenomenon, which were further enhanced
by the picturesque setting of Barra Grande. As the time passed, the
pileus cloud showed intricate twisted patterns that added a special
beauty to that evening sight and resembled large moving veils in the
sky.

In addition to the iridescence, something else caught my attention on
the scene. Perhaps victim of a pareidolia event caused by such an
amazing view, the cumulus cloud resembled to me a dog that was wearing
a colored hat and staring at something far away out of the field of
view. The pileus clouds, when favorably positioned relative to the
Sun, can yield iridescences of incredible beauty and show an
eye-catching view that we will never forget.

Baseball player Yogi Berra was famous for quotations such as “It’s
so crowed, nobody goes there anymore.” Perhaps they shouldn’t.

While places such as the Grand Canyon, Yellowstone and Yosemite host
crowds that often overrun the facilities, as well as overrunning the
visitor experience, other scenic sites in the United States are,
arguably, just as beautiful and virtually undiscovered. One such place
is the Grand Staircase-Escalante National Monument in southern
Utah. Both the variety of landforms and the expansive size make this a
crown of the hidden jewels.

The Circle Cliffs is an anticline in which the central portion has
been eroded down, while exposing the youngest layer as cliffs that
surround the internal valley. This anticline encompasses hundreds of
square miles of juniper, dotted high desert. In most of the
Monument, facilities are non-existent. The Burr Trail is a paved
road that crosses the Circle Cliffs Valley. Other roads are unpaved.
