Pack Creek fire...

flares again on this extremely hot and dry afternoon. The fire complex has grown to nearly 6,000 acres in size over the last four days and is located about 11 miles south of Castle Valley.

Fire season commences...

with explosive vigor in the Pack Creek drainage in the foothills of the La Sal Mountains, just south of Moab, Utah. This fire broke out yesterday and filled Castle Valley with smoke beneath mostly cloudy skies, with most of it clearing out overnight. Then today, shortly after noon, the strong winds fanned the fire into full intensity once again. Yikes.

Around 3 pm MDT the smoke plume grew considerably larger in size.

Here are live updates. Spoiler: The fire was human-caused by an unattended campfire, according to the U.S. Forest Service and Utah Department of Natural Resources.

Star trails over Castle Valley...

and a bonus meteor (!) as twilight descends on the landscape. This shooting location is in Professor Valley, immediately to the east of Castle Valley, just on the other side of Castleton Tower. This image was shot as I scouted a location for capturing the Milky Way later in the evening, rather, early the following morning.

Cumulative twenty minute-long exposure consisting of 40 individual images, each 30 seconds long, stacked and blended with StarStax software.

Fiber optic cable...

has been pulled through the recently buried orange conduit to the back wall of my rural home. The 21st century is getting closer!

Now all that is needed is an optical network terminal that bridges the glass-copper connection to the home and converts pulses of light into electrical signals for the router. Faster, please!

Virga represented in pictographs...

in Buckhorn Wash, Utah?

Large anthropomorphic “angels” showing wings that appear to represent virga falling from the sky.  Are these depictions of rain gods?

Lightning strike...

on Porcupine Rim early this evening as a storm rolls over Castle Valley from the west.

There was a stiff wind blowing as indicated by the horizontal windsock, but unfortunately, no rain.  And the good news is that there were no ground strikes in the valley itself.

Towards the east, a curtain of virga falls behind the incredibly scenic skyline as sunset approaches.

Lightning is extraordinarily difficult, and sometimes dangerous, to photograph. I can highly recommend the Lightning Trigger LT-IV by Stepping Stone Products, a device that controls the shutter release on a camera within milliseconds of detecting the flash. Also, consider your safety first!

Active weather over the La Sal Mountains...

this hot and windy afternoon. Could be an exciting late afternoon with lightning but I hope we get some rain.

I estimate the highest cloud tops to be around 28,000 feet in this image that I shot returning from my sojourn to see the Comet Thrower.

The Comet Thrower...

pictograph in upper Hellroaring Canyon is a huge anthropomorphic figure that appears to toss (catch?) a comet! I chose today for a sporting (climbing) descent into the canyon to visit this fascinating panel because around 11 am on the 30th of May a narrow shaft of light illuminates the figure for only a few fleeting minutes. I wanted to witness this archeoastronomical event for myself. It was just me and the Thrower today. Priceless.

The curvature of the rim of the Wingate Sandstone escarpment controls the play of the Sun’s rays on the big wall, especially on the Comet Thrower pictograph (lower left).  Those are the Kachina Spires in the distant lower right.

A triangular beam of light sweeps across the Comet Thrower between 10:50 am to 11:00 am on 30 May every year.  The brightening occurs very slowly at first, a subtle thing, then proceeds in a counter-clockwise movement as it becomes increasingly lit.  Wonderful.

Tip of the hat goes to RT of Castleton who alerted me to this phenomenon that he first observed years ago. Thanks!

Engineering digger bees...

have constructed these miniature sedimentary towers, so-called turrets, only a couple centimeters (less than an inch) high as entrances to their subterranean nests. These are the same bees (Diadasia diminuta) that collect pollen from the desert globemallow plant (Sphaeralcea ambigua). Industrious little diggers!

Bees exit the nest in a backwards direction.  In doing so they lift loose sediment out of the turret on their backs.

For macro photography you must get CLOSE to the subject, and in this case, down on your belly!

Collared lizard photo festival...

today, and why not? They’re real and they are spectacular!

Once again I want to thank R & C for allowing me access to their lizard-rich property in Castle Valley.  I’m shooting the big guy from about three meters (10 ft) away with a tripod-mounted Canon 5D Mark IV and Canon EF 500 mm prime lens.

Sunset at Fisher Towers...

last night as I was preparing to photograph the rising full moon that was, unfortunately, obscured by clouds.

Classic view of Fisher Towers during golden hour.

Big Bend meander...

on the Colorado River at dusk this evening, with light traffic on Utah 128 between Moab and Castle Valley.

Image beta: This was shot a little after 9 pm after I had scrambled about 400 ft up the steep and loose talus-mantled slopes to near the base of Dolomite Spire. Tripod-mounted Canon R6 with Canon EF 16-35 mm lens at 16 mm focal length, 20 sec exposure at f/22, ISO 2000.
