Animal eye detection and auto-focusing...

on the Canon EOS R6 is nothing short of revolutionary. While I’m not at all happy with any of the image compositions and exposures below, the focus is tack sharp on the eye, where it should be. In addition, these were all shot through a horribly dirty window and nearly directly into the sun. No fill flash was used as birds were illuminated by reflected sunlight.

UPDATE: I’ve cleaned my windows now. What a difference that will make!

The Canon EOS R6...

is the newest camera in the quiver, incorporating the latest in mirrorless technology, and mates (with an adapter) to my array of Canon EF lenses.

The early mountain biker...

gets to lay down the first tracks, especially fun after a two-inch dusting of snow in Castle Valley last night.

Sharp-Shinned Hawk...

perched in the ash tree next to the feeding station on a snowy day, patiently waiting for an opportunity to grab a meal. I shot this through the kitchen window after patiently waiting for the right opportunity myself.

What if...

Castleton Tower toppled? Perish the thought!

Or, alternatively, another sandstone tower was present atop Baby Carriage Rock, as there almost certainly was in the distant past?

Geometric artwork of hoarfrost...

is sustained in deeply-shaded areas where temperatures never rise above freezing, coupled with a right amount of moisture in the chilled air. The ice crystals comprising the surface hoar that is pictured below are much like icy corn flakes and about the same size.

Rockfall from Porcupine Rim...

in Castle Valley, Utah occurred around 1 am MST, and was so loud that it woke me up! I stoked the fire in the wood stove and went back to bed, finding the small scar and debris run-out only after sunrise. It’s the geology of now!

Sir Ernest Henry Shackleton...

died on this day in 1922 in Grytviken, South Georgia, and is buried in the graveyard just outside the historic and remote whaling station. On the evening before he passed away, after returning to his ship in the harbor - the Quest - he wrote what was to be the final entry in his log book:

Using the SkySafari planetarium program, entering the location, time and date of that fateful night in Grytviken, this is the starry sky that Shackleton would have witnessed. Sirius and Canopus are the two brightest stars in the night sky, and he was almost certainly writing about one of them.

Sir Ernest Shackleton is one of my great heroes, leading the entire crew of the Endurance to an epic rescue in brutal Antarctic conditions on the ill-fated 1914–1917 Imperial Trans-Antarctic Expedition. I will certainly raise a toast to him today, the 99th anniversary of his death. RIP.

Birds taking refuge...

First and only tracks...

after the slow-moving snowstorm that dropped about seven inches on Castle Valley during the last two days.
