Morning Fog at Mormon Lake

A few days of tropical moisture—remnants of Tropical Depression Nora—brought widespread rainfall to much of northern Arizona. As the moisture was replaced by drier air in the middle- and upper-levels but was unchanged in the near-surface layer, we were left with a situation in which fog might form in the early morning hours.

 

So, up before dawn to drive out to Mormon Lake and the surrounding basin. And there was fog—at least in one corner of the basin. Here is a 30-minute time lapse compressed down to 17 seconds showing the movement of the fog as it sloshes back and forth.

Heavy Rain, Low Clouds and Wildflowers

We have had an extended period of heavy rain across Northern Arizona this week with some of the 7-day rainfall totals exceeded 5 inches. After a night of heavy rain we had several hours of fog and low clouds the following morning. I went to Anderson Mesa southeast of Flagstaff to get above the fog. Unfortunately, the fog layer was too deep and there was also a layer of clouds above so there was no morning light. Still, the fog drifting through the Lower Lake Mary area was interesting.

Later in the morning I shot this photo of the lifting fog and low clouds with the San Francisco Peaks in the distance.

Snow and Fog in Sedona, Arizona

A late-season winter storm brought snow to the high deserts of northern Arizona. An early morning check of weather conditions indicated that Sedona airport (KSEZ) had reported snow. And satellite data showed an area of fog in the Verde Valley, including Sedona. This had the potential to be a great opportunity for photographs.

The early morning visit to Sedona was worth the effort. And the trip home included a stop at the recently re-opened Indian Gardens  Cafe in Oak Creek Canyon.

A Late Winter Storm

A winter storm brought snow, clouds, and fog to some of my favorite photographic locations. The early morning sun lights up a band of clouds that encircles the San Francisco Peak. Below the peaks, fog lies in the low areas of both Upper and Lower Lake Mary.

A smaller area of fog sits in the corner of the Mormon Lake basin and partially obscures some of the old ranch buildings.

Comet 46P/Wirtanen, Rocket Launches, and Fog

I went out to the Mormon Lake Overlook early last evening (12/08/2018) to photograph a couple of different events. First was the launch of the ULA Delta IV-Heavy NROL-71 mission from Vandenburg Air Force Base. After that, I planned on pointing the camera up towards Comet 46P/Wirtanen.

Only part of my plans worked out. The launch was scrubbed at T-7 seconds but I didn’t know about that until much later. I just kept shooting a series of 15-seconds exposures pointed towards the western horizon and hoping that I would capture it. No launch—and there was nothing to capture.

But, wait, not so fast! It turns out there was a shallow layer of fog in the Mormon Lake basin and the series of 15-second exposures over a period of about 10 minutes resulted in a nice time-lapse movie of the fog. Unfortunately, the camera was pointed at mostly sky with very little of the ground but I’m happy with the lucky result.

Next, I shot a series of 60-second exposures of the comet. Although the skies were cloudless, there was a lot of moisture in the air. See the discussion above about fog! The presence of this moisture and very thin fog above resulted in very colorful stars. A nice effect.

For the third act, I pointed the camera back down and over the lake basin towards Flagstaff. The fog was dissipating at this time but still shows up well. What also shows up is the large amount of light pollution in Flagstaff. Flagstaff is the worlds First International Dark Sky City but it takes a lot of work to keep the skies dark. I fear we may be losing the battle.
