West Fork Oak Creek. This is the “Subway” section of the canyon.
A week of cold overnight temperatures has allowed ice to form on West Fork of Oak Creek–so this was a good time to hike the canyon. Winter visitation is fairly light so getting a parking spot is easy and we encountered only a handful of hikers on the trail. So it is definitly more enjoyable in the winter.

There was ice on the creek but there was also open areas of running water. It required some care making the numerous stream crossings to step on logs or rocks and not to put too much weight on the ice. A big difference from previous winter hikes was the lack of snow. Although we carried foot traction devices (i.e., Kahtoola microspikes) we did not need them.
At the “Subway”, a narrow, high-walled section of the canyon with wall-to-wall water, the ice was probably not thick enough to ensure safe passage through this section. Some of it was firm but there was still open water in the middle of the channel. Opting for safety, we let this be our turn-around spot.
There are several cliffs in the canyon with significant water seeps. Water drips from the large icicles and refreezes at the ground creating free-standing ice stalactives as well as encasing grasses and small stems in strange and bizarre shapes.

I looked back at the many times we have done this in the winter and the conclusion that I can draw is that it requires multiple nights of sub-zero temperatures (generally -5 to -10°F or colder) to produce safe ice. The recent cold temperatures were single-digit readings but above zero. Not cold enough.

Here are some older entries about hiking West Fork in the winter:
There was a lunar occultation of Mars on the evening of 13 January 2025. An luncar occultation is when the disk of the Moon (or Luna) passes in front of a star or planet. This was an easy event to observe with the Moon low in the eastern sky.
The Moon and Mars. Mars has just reappeard from behind the lunar disk.
My plan was to shoot several/many images of the ingress and then multiple images of the egress. Unfortunately, most of the images (but not all) were out of focus. I suspect that the rapid cooling of the telephoto lens was the cause of lost focus. Once I noticed the issue and re-focused it stayed in focus.
Time lapse of the Moon and Mars.
I shot images at 3-second intervals as egress started then switched to 30-second intervals. These were assembled into a time-lapse video, shown below.
The next Moon-Mars occultation visible in North America will occur in February, 2042.
Fall (or autumn, if you prefer) is over in northern Arizona. Peak fall colors started high on the peaks back in September and have been working their way down to lower elevations. The peak moved through Oak Creek Canyon in mid November.
The North Wilson Trail climbs out of Oak Creek Canyon and goes through a stand of maple trees. Leaves on trees and on the ground make this a favorite for fall photographs.
A few years ago and saw this little guy sitting at the base of the tree on the North Wilson Trail. He was still there on this year’s hike but was starting to lean over a bit so we set him upright. Never know what you’ll find on a hike.
Not really about fall colors but we spotted this little gnome statuette off to the side of the trail.

The Waterline Road in the San Francisco Peaks reopened in October. It had been closed for more than two years in the aftermath of the Pipeline Fire. That fire occurred in the same area as the Schultz Fire (2010) and managed to burn what had been spared by the earlier fire. After two years of work, the Waterline Road was safe for the general public to use again.

The hill on the far right was burned by the Pipeline Fire but is beginning to recover.
We rode our mountain bikes up the road and were saddened–but not surprised–by the destruction of the fire. There had been a lot of new growth after the 2010 fire–especially with new aspen trees already attaining heights of 10 to 20 feet. All this burned in 2022. Once again, new growth is taking place but most of it is still quite small.

The Inner Basin, however, was mostly spared by the 2022 fire and here were many aspen trees in full autumn colors. Along the road there are a few locations where you can get a wider view of the trees and the mountains but mostly the only view along the road…is the road.
A previous post showed many images of Comet C/2023 A3 (Tsuchinshan-ATLAS) taken when the comet was visible in the morning sky. The comet then moved between the Earth and Sun making it difficult to see. A period of 10 days passed between my last morning images and my first evening images.
At first, the comet was difficult to see in the bright evening twilight and the presence of the Moon made it even more difficult. But each day the Moon rose later in the evening and the comet rose higher in the western sky. I was able to take advantage of clear skies and shot photographs on eight days. Here are some of the best photographs from those sessions.

I had already shot images of the comet while looking to the east across Ashurst Lake when it was a morning object. Now it was time to shoot looking to the west across the Lake. The comet was very bright and easy to see. I also shot a long sequence of images to create a time-lapse video of the comet setting in the west.

The next evening I set up at the Arizona Snowbowl parking area–along with dozens of other comet watchers. It was fun to listen to folks admiring the comet and the joy from the kids when they were first able to spot it in the darkening sky. The anti tail was even easier to see on this night compared to the previous evening.

The Moon was still a factor in the evenings but the comet was getting higher in the sky so it balanced out. On this evening I went to The Narrows at Upper Lake Mary since that section of the lake is oriented WSW-ENE. This meant I could photograph the comet above the water and get a reflection of it in the water. That worked out pretty well.

A few days of clouds shut me down but by this day it was very clear and the Moon was no longer a problem. I opted to use a longer telephoto (180mm) for these shots even though it might truncate part of the tail. The anti tail is still visible but is much less striking than in earlier days.

The comet was continuing to rise higher in the western sky and was closer to the Milky Way so I switched back to ultra-wide angle lenses to capture both. Bonus: I was able to again capture the comet and tail reflected in the waters of Lake Mary. For the very wide image shown here I did a composite. The first image had star tracking turned on to get sharp stars and comet; the second image had tracking off to get sharp foreground. These were then combined and blended in software.

The comet continued to climb higher, become dimmer, and have a shorter tail as it moved away from Earth and Sun. I switched to a short telephoto (85mm) to shoot a sequence of images which were then stacked to reduce image noise. I was also able to use the sequence to create a short time-lapse video to show the movement of the comet over a period of about 45 minutes.

As the comet climbed higher it also was closer to the Milky Way and I again tried to get a shot with both features. This was taken with at 35mm focal length.

As the comet retreats it is getting smaller in the sky and it is better to use medium length telephoto lenses. Here is an image taken with the Nikkor 180mm ED AI-S lens, a legacy, manual focus lens.

What’s next?
We are once again in a period of clouds. When skies are once again clear the comet will be much farther away, smaller, and dimmer. At this point, it will require longer exposures and bigger telephoto lenses. It should be fun!
