Common Buckeye Butterfly (Junonia coenia) — Image by kenne
So, I begin researching articles on butterfly color and found “The evolution of color:
How butterfly wings can shift in hue” in ScienceDaily. They found that buckeyes
and other Junonia species can create a rainbow of structural colors simply by tuning
the thickness of the wing scale’s bottom layer (the lamina), which creates
iridescent colors in the same way a soap bubble does.
“In each Junonia species, structural color came from the lamina. And they are producing
a big range of lamina thicknesses that create a rainbow of different colors, everything
from gold to magenta to blue to green,” says first author Rachel Thayer.
“This helps us understand how structural color has evolved over millions of years.”
You can find more information structured color at Marine Biological Laboratory.

Boulder Dam Viewed from the Arizona Side (November 5, 2020) — Panorama by kenne
Most of the time, when we drive to Las Vegas from Tucson, we pass by the dam.
The last time we stopped, we drove the two-lane road on top of the dam on our way back
to Houston in 2007. The Mike O’Callaghan–Pat Tillman Memorial Bridge was under
construction and was not completed until 2010. The drive across the Boulder Dam
would take quite a while, depending on the volume of traffic.

Currently, the Lake Mead water level is 147.41 feet below the full pool of 1,229.00,
40% of its full capacity. The Colorado River, which supplies Nevada,
Arizona and California, most of its water, has long been chronically overused
and has dwindled during two decades of mostly dry years. The drought has been
worsened by higher temperatures unleashed by climate change.

“Wilderness is not a luxury but a necessity of the human spirit, and as vital to our lives
as water and good bread. A civilization which destroys what little remains of the wild,
the spare, the original, is cutting itself off from its origins and betraying the principle of
civilization itself.”

“Afoot and light-hearted I take to the open road,
Healthy, free, the world before me,
The long brown path before me, leading me wherever I choose…
Allons! whoever you are! come forth!
You must not stay sleeping and dallying there in the house, though you built it, or though it has been built for you….
Allons! be not detain’d!…
Allons! the road is before us!”
— Walt Whitman
“Earth, Sky and Tumacácori” — Photo Artistry by kenne
A priestly man
once traveled
the desert southwest
mounted a horse
armed only with love
a force without
a presidio of soldiers
connecting with people
of many tribes
building adobe missions
each opened to the morning sun
located within walking distance
understanding the desert paradox.
