Growing up with hardwood trees of Wisconsin, it was a beauty to appreciate. However, as a kid and seeing nothing of the world beyond a small portion of Wisconsin, I didn't know it had special autumnal beauty. There is scenic beauty there no matter the time of year. However, with the autumnal equinox in the northern latitudes, the colors change from green to a rainbow of colors. The sugar maple becomes a blazing red.
This is from my journey through Wisconsin in the fall of 2008.
The surrounding Tucson desert doesn't have those autumnal colors of the northern latitudes. However, the monsoon rains have kept the desert green. The summer monsoons were followed by hurricanes off the coast of Baja Califonia which sent more moisture into southern Arizona.
This was the Autumnal Equinox green view this morning as I hiked Saguaro NP East.
The Catalina Mountains have some small stands of aspen. With cooling temperatures, those aspen will take on their autumnal hue of yellow. Time to consider that as a hike destination.
