I like most the photos of Etna.
"The sky before us was covered with thick and low clouds, while
high above them a singular phenomenon was observable. It
was striped white and grey, and seemed to be something
corporeal ; but how could aught corporeal get into the sky ?

was a side of Mount Etna, which appeared through the
opening clouds. Snow alternating with the crags formed the
stripes." J.W. Goethe, Italian Journey (Monday, April 30, 1787)
P.S. After your departure something happened like this:
