I learned something new today.
www.gibmuseum.gi/our-history/...
In 711 AD, Berber troops from North Africa, under their leader Tarik ibn-Ziyad, landed at the foot of the Rock setting the Muslim conquest of Iberia into action. The modern name Gibraltar is a derivation of the older name ‘Jebel Tarik’, meaning Tarik’s Mountain. Apart from a brief period 1309-1333, the Muslims occupied Gibraltar for over 750 years, until finally ousted by the Catholic Monarchs in 1462 during the eighth siege of Gibraltar which formed part of the Reconquest. Surviving structures from this period include parts of the Line Wall, Moorish Castle and the Moorish Baths located within the Gibraltar National Museum building.

Even cloud seas have rising tides it seems.
A desert scrub hillside is visible in the foreground, and behind it, an expanse of clouds covers the Mojave Desert. To the left, a finger of the Sierra Nevada mountains is visible extending down into the milky vapors below.

If anyone was curious as to what the edge of a Great Horned Owl and Red Tailed Hawk's outermost feather looked like, this is your lucky day. The "fringes" as they are called on the owl are believed to break up the air to aid in the bird's silent flight.
The magnified edge of a Great Horned Owl P10 feather, showing the characteristic fringes. They look somewhat like hairy eyelashes. The magnified edge of a Red Tailed Hawk P10 feather, showing the lack of fringes. Unlike the owl, the hawk's feather comes to a more abrupt end.
