Fall Colors All Around

The last week has given us spectacular skies--
clouds that linger for the afternoon,
and part just as a red sun begins to set.
Rayleigh scattering, the explanation for the colors in blue skies and red sunsets, from small particles within the atmosphere that reflect light, perhaps even more apparent in this time of drought.



A hint of color, late in the day.


With each step closer to the horizon, a deeper shade.


Until, against a dark blue sky, broad orange reflection--
the backdrop to rich purple clouds.


A reminder that from adversity comes beauty.
And unpredictably happy endings.
