A previous post talked about mountain biking in Flagstaff along the high elevation sections of the Arizona Trail. Not too far away is another section of the Arizona Trail — this time at an elevation of about 6500 feet. The vegetation is different — and quite green because of all the rain lately — and the trail is more open.
This particular section of the Arizona Trail starts along Old Walnut Canyon Road on the north boundary of Walnut Canyon National Monument. It travels through Ponderosa Pine then moves into Pinyon-Juniper with wide open vistas. There are old homesteads along the trail with collapsed buildings and old toys in what was once someones yard.
Flagstaff has a variety of great mountain biking trails. Some of these trails start right in the city or at the city edge; others require only a short trip out of town to the trail head.
In addition to local trails, sections of the Arizona Trail pass through Flagstaff and the nearby mountains. One of the newer sections north of town has some excellent riding through groves of aspen trees.
This is an amazing ride when the leaves begin to change color in the autumn and the shadows start to get long.
It’s also a good idea to keep a sharp eye for elk wandering through the woods and along the trail. After all, it’s important to share the trail with ALL users!
Earlier this month it was apparent that there would be one final night of exceptionally clear skies before theÂ summer monsoon pattern set up and skies would be cloudy more often than clear. I thought another night sky image with reflections of the stars in water might be interesting so I ended up at Lake Mary a few miles southeast of Flagstaff. I was surprised to see how much light pollution there was in the southern sky. This stray light is coming from Phoenix, located over 100 miles to the south. There is so much light that it is even reflected in the lake — as are a few of the stars.
A very short distance to the north of where this image was taken is the Anderson Mesa astronomical station. It’s hard to believe that they can still gather useful observations of the sky with this much light pollution. Finding truly dark skies is becoming a global challenge.
The summer rainy season is now in full swing across the southwest and the skies are cloudy most of the time. I’m no longer able to shoot images of the stars, planets, moon, or other celestial bodies. I’ve turned my attention to the daily thunderstorms that pop up across northern Arizona during this period.
I’ve been trying to capture daytime lighting photos for many years. The old way was to set the camera on a tripod, point it at an active storm, and attach the shutter cable release. Then I would hold the release with my thumb on the trigger and when I saw the first flicker of lighting I would push the release. A fairly crude method but it does work since the duration of a lightning flash, though short, is often long enough if you have fast reflexes.
Nowadays, though, photographers can build or purchase an electronic lightning trigger that does essentially the same thing but is much faster and more reliable. Here’s a photo taken a few days ago in Kendrick Park in northern Arizona as a thunderstorm moved across the cinder cones of the San Francisco Volcanic Field. Taken with a 28-mm wide angle, the image has been cropped to highlight the lightning flash.
The downside of capturing an image in this manner is that the initial stages of the lightning flash are not captured since it is this phase of the lightning sequence that triggers the lightning device. This early stage of a lightning flash is typically where all the branching and filaments occur. The bright part of the flash captured here is a return stroke that is mainly an upward transfer from the ground to cloud along a single channel.
Compare the previous image with this nighttime image (scanned Kodachrome 64 slide)Â taken many years ago. In this image, I left the shutter open for an extended period of time (typically 10 to 30 seconds) before the flash and then closed the shutter immediately after the flash. This captured the downward traveling stepped leader and the multiple paths before the main upward stroke occured.
It would be great if the modern lightning trigger devices could react to the first few microseconds of the stepped leader and trigger the camera shutter and capture the multiple paths and stepped leader. Perhaps such a device may one day be available.
On a recent “First Friday Art Walk” in downtown Flagstaff, I had the opportunity to photograph two different dance troupes. The first performance (The Gypsy Chicks) was outdoors in the evening twilight on Heritage Square; the second performance (Troupe Shuvani) was indoors at the Flagstaff Photography Center.
I shot many images of both troupes but these two photographs stand out. And I think it is because the dancer is making “eye contact” with the camera.
