The footprint of flood impacted areas...

throughout Castle Valley is clearly seen in the recently updated satellite imagery available in Google Earth and Google Maps. Light-colored sedimentary deposits paint the areas affected by overland sheet-flooding and where floodwaters escaped ditches and natural channels. Compare and contrast.

Imagery date: 7 August 2024.

Erupting in a matter of hours...

from the lawn, this phallic fungus emerges on schedule in October. About a half dozen of these pungent and indecent structures have developed so far, likely triggered by the recent rains. Impressive.

Common stinkhorn (Phallus impudicus).

Odorous chemicals in the slimy cap attract insects which will collect spores and spread them to other locations.

UPDATE: The following day, still standing erect but the cap has been consumed by insects, still attracted to the pungent odors.

Elusive comet C/2023 A3 Tsuchishan-ATLAS was finally spotted...

shortly after sunset this evening, low to the west, hovering midway between Venus and Arcturus. Its size and brightness exceeded my expectations and the comet was easily observed with the unaided eye around 8 pm MDT as I snapped a series of images using different lenses.

Despite the nearly full Moon, the comet was initially spotted with binoculars, and then it became an easy naked eye object.

An automobile zooms along Highway 128 on the right, the occupants of which have no idea of the astronomical spectacle they are missing. That’s the planet Venus shining brightly in the lower left of the frame.

Sunset in the Cisco desert...

this evening where there’s an unobstructed view of the western horizon across the flat and desolate landscape of Sagers Wash. I was out of the canyons, chasing a comet yet again, and all I came home with was this lousy sunset. No complaints, it was an absolutely lovely evening.

SpaceX shows NASA how it's done...

in the 21st century with a historic launch and capture of the largest object ever put into space early this morning. It’s unfortunate that this incredible accomplishment isn’t receiving more news coverage.

I’m not so sure that Elon Musk isn’t an alien.

Images below are screenshots from the live stream provided by SpaceX.

One minute before launch the Super Heavy Booster and Starship are fully fueled with liquid oxygen and liquid methane.

Liftoff as 33 Raptor engines on the Super Heavy Booster generate twice the thrust of the Saturn V, capable of placing 150 tons into Earth orbit.

Super Heavy Booster hovering at the launch tower after return from flight. Entirely unprecedented. Wow!

It’s pretty clear that NASA needs SpaceX more than SpaceX needs NASA. Per aspera ad astra.

Terrible air quality...

for the third day is affecting the eastern Utah region due to the Yellow Lake fire in the western Uintah Mountains. It’s going to take a change in wind direction to clear out the smoke and haze.

Link to Fire and Smoke Map 4.0 for latest air quality conditions.

Smoky conditions in Castle Valley obscure the higher La Sal Mountains and Round Mountain shortly after sunrise.

Back in the bike saddle...

again in Castle Valley, Utah with the Trek full suspension e-mountain bike turning 3,000 miles on today’s ride. Since September 2020 the cumulative mileage on all my eMTBs comes to 14,357 miles (23,110 kilometers), or 57.6% of the Earth’s circumference at the equator. I’m feeling a bit like Forrest Gump during his running phase.

Sunrise in the Professor Valley...

paints this golden panorama of an amazingly scenic terrain. I was out in the predawn to chase an early morning comet, but having met with no success, I returned with this expansive image. It’s a helluva back yard. You’d think the movie industry would like to film around here.

The Thiokol rocket garden...

in remote northern Utah displays all the rocket engines and missiles they manufacture at full scale, now under corporate ownership by Northrop-Grumman. I have an enormous case of rocket envy.

The rocket garden is free and open daily to the public and includes interpretive signs and related displays. Well worth a visit if you’re heading to the Golden Spike National Historical Park which is nearby.

The submarine-launched ballistic Trident (center) with the three-stage land-based Minuteman ICBM (left of center). The enormous solid rocket booster for the Space Shuttle lays in the background.

The business end of the Space Shuttle’s solid rocket booster. When ignited, a pair of these provided 85% of the thrust at liftoff for the first two minutes of ascent. Unfortunately there are no demonstrations.

Re-entering the Colorado Plateau...

after the summer’s absence via the San Rafael Swell. There’s no place like home.

Three well-preserved Miocene-age tree molds...

occur in the Wanapum Basalt Formation (Columbia River Basalt Group) along the Fish Lake Trail, exposed in a railroad cut through the volcanic formation within 100 yards (meters) of one another. One can easily imagine a landscape with a stand of large trees being invaded and enveloped by an advancing lava flow around 15 million years ago. I’m certain that 99% of the trail users aren’t aware of these interesting features and the story they tell.

Note the silicified wood that is preserved near the base of this large tree mold.

This tree mold is about 20 inches (0.5 meters) in diameter.

The underlying paleosol (ancient soil horizon) in which the tree were rooted is clearly seen here beneath the overlying basalt formation. This tree mold is about 15 inches (0.4 meters) in diameter and penetrates the interior of the volcanic unit.
