The Rincons are one of 42 Sky Mountain islands isolated from each other by the gradual warming and drying climate changes since the last ice age, 10,000 years ago. While this marvelous environment of oak and pine forests only accessible with much effort on foot, it is literally visible from every point of the Tucson valley and million human inhabitants.
Coronavirus is raging this March 20th (I schedule posts several weeks ahead now), on this day of our anniversary, easy for me to remember falling close to or on the Spring equinox. Earliest spring flowers were up for a week when I spied this group of crocus blooms on a hill. We do not remember them being there, so I called Pam to enjoy them.

These are extra special, Pam’s parents planted them years ago. The above images are the same photograph. On the left, white balance is set to “cloudy.” At the time, late afternoon, the sun was behind low clouds, providing back light. Perfect lighting for flowers, which is why I interrupted springtime yard cleanup to run inside for the camera.
My intent was to increase the f-stop to over 20 for the following photograph. Metadata on the photograph shows I was only successful in increasing it from 5 to 5.7. ISO was increased from 100 to 400. There was an intermittent breeze and my intent was to avoid blur.
In retrospect, I neglected to change to Aperture mode so any change to F-stop I made was reset. This is a beginners mistake, so photograph turned out well. The colors are richer in the f/5.7 shot.

Here is the east side of the inner enclosure wall of Dun Aonghasa (Dun Aengus) where it ends at a cliff edge over the Atlantic ocean.
Visible are the last 60 feet or so of the limestone strata supporting the inner ring.
When first constructed, the inner ring was complete, the western side 1,000 feet from the cliff.. Today’s form of a semi-circle was created by nature when the force of Atlantic Ocean waves eroded the cliff, undercutting the strata.
Look close to see a fracture where the next block of limestone will fall into the waves.
