Cirrocumulus clouds form at high altitude. They are primarily composed of ice crystals but also contain supercooled water droplets.
The photograph of cirrocumulus clouds was taken in Las Virgenes Canyon on a trail run from the Victory Trailhead of Upper Las Virgenes Canyon Open Space Preserve, also known as Ahmanson Ranch.

The photographs above show the rapid development of the pyrocumulus clouds associated with the Lake Fire, near Lake Hughes. The timestamps are approximate.
According to the Lake Fire incident page, the fire was first reported on August 12th at 3:40 p.m.
The photographs were taken during a run at Sage Ranch Park. This is the location of the Sage Peak1 and Sage Peak2 ALERTWildfire cams.

While doing the Bulldog Loop earlier this year, I encountered an enthusiastic hiker who commented, “Aren’t the wildflowers amazing?”
He added, “There are so many, uh… What’s it called? You know, the one that smells like maple syrup.”
“Do you mean Everlasting?” I asked.
“Yea, that’s it! California Everlasting,” he exclaimed.
That’s what people remember about California Everlasting — the leaves smell like maple syrup.
The somewhat nondescript plant is especially abundant this year.
As suggested by its name, California Everlasting (Pseudognaphalium californicum) can be found along trails in Southern California chaparral and coastal sage-scrub just about any month of the year.
The plant looks like it is blooming in the title photo, but each “petal” is a botanical structure called a phyllary. The phyllaries form a protective covering around a disc of tiny flowers as they develop. Here is a closer view.
The plant dries out in the Summer, but the flower-like structures often remain – an everlasting dried flower arrangement.
The photos are from this morning’s run to Calabasas Peak on the Secret Trail.

My weekday runs at Ahmanson Ranch will frequently include a dirt road on the east side of Lasky Mesa that is part of the Mary Wiesbrock Loop. There is a fence line along the road, and almost without fail, I’ll see a bird or two on the fence.
The most common fence-sitting birds on this stretch of road have been the Say’s phoebe, western kingbird, mourning dove, and lark sparrow. Occasionally, I’ve also seen a kestrel or northern harrier taking in the view.
While phoebes and kingbirds sometimes play bird games, hop-scotching from fence post to fence post, raptors are exceptionally wary and fly away at the slightest provocation.
Today, I was running down the road and spotted a dove-sized bird sitting on a fence post. As I approached, I could see that it was a kestrel and expected it to make a quick exit.
Slowing to a walk, I stopped directly across the road from the small falcon. It was about 20′ away, and didn’t take flight.
The only camera I had was my iPhone, so it had to do. I slowly took the phone out of my pack and tapped a camera app. The bird cooperated, and I took a few photos. But I wasn’t close enough.
Had the kestrel flown? I selected the 2X view. Still there. I took a couple more photos.
Finally, the falcon became impatient, and in a characteristic motion, jumped into flight.
This year I’ve seen kestrels on Lasky Mesa frequently, and suspect the mesa is about the right size for a mated pair’s territory.
Update August 5, 2020. The kestrels have been very wary lately, flying away just when I get within camera range. Here’s a photo of the male kestrel from this afternoon’s run.
Update July 30, 2020. I’ve seen at least one of the Kestrels just about every time I run on Lasky Mesa, but have been unable to approach anywhere near as close as described above. Here’s a photo of one of them perched on a fence post on the south side of Lasky Mesa. It was taken with the equivalent of a 230 mm telephoto lens. Based on its coloration in flight, it appeared to be a female.

Over many years of running in Upper Las Virgenes Canyon Open Space Preserve (Ahmanson Ranch), I’ve noticed that the height of Elegant Clarkia is closely related to the amount of Spring rainfall. During some years of our most recent drought, the plants were short and scarce.
Spring 2020 was particularly wet in the Los Angeles area. Downtown Los Angeles (USC) recorded 179% of normal rainfall in March, and 332% in April. This was the wettest March and April in Los Angeles since 1992.
This year’s bloom of Elegant Clarkia is the most profuse I’ve seen in Upper Las Virgenes Canyon Open Space Preserve. Look for Elegant Clarkia along the Lasky Mesa Trail and along the Mary Wiesbrock Loop Trail on the north side of Lasky Mesa.
Another Clarkia currently blooming at Ahmanson Ranch is Purple Clarkia (Clarkia purpurea). Look for it along East Las Virgenes Canyon Road/Trail.
