Fogbows form opposite the sun in a manner similar to rainbows, except the water droplets that create a fogbow are much smaller than raindrops. Because a fog droplet is so small, the physics of the interaction is different. The result is often a diffuse, primarily white bow.
The photograph of the fogbow was taken Sunday morning on an out and back run from Wendy Drive to Mugu Peak. The sun was about 14 degrees above the horizon. More about fogbows and other atmospheric phenomena can be found on Les Cowley’s Atmospheric Optics website.
Mustard flowering in Cheeseboro Canyon reveals the underlying structure of a hill.
According to the Dibblee geologic map of the area, the strata are part of the Modelo Formation. And… the Modelo Trail passes directly over the top of the hill.
As I neared the top of Topanga Lookout Ridge, I could hear music coming from the Lookout. It looked like there were people on top, but from my vantage point down on the ridge, it was hard to tell what was going on.
When I reached the isolated platform, I was surprised to find a couple dancing! Wearing masks, and with much of the San Fernando Valley as a backdrop, they had found a unique way to deal with the complications of the pandemic.
Updated June 26, 2023. The spiral has been periodically removed and rebuilt over the years. Google Earth historical imagery shows that it was removed sometime between March 2021 and February 2022. As of June 25, 2023, it had not yet been rebuilt.
Instead of struggling to escape a tar pit, this “mammoth” seems to have been caught up in 25-30 million-year-old sandstone.
The beast can be seen along the Backbone Trail, east of the Corral Canyon Trailhead. When running/hiking/riding east from the trailhead, the trail climbs over two steep steps and up to gap in the rock. In the photo above, the gap is on the left and the mammoth figure is on the right. From the gap, the trail descends a rock corridor to Mesa Peak fire road.
A closer look at the mammoth reveals that it is pockmarked and there are rocks embedded in the sandstone. The embedded rocks are cobble from an ancient river and the pockmarks are where rounded rocks have fallen out of the eroding sandstone.
Stream cobble that has eroded out of sandstone formations in this area has been used to construct a spiral labyrinth on the north side of Mesa Peak Fire Road. The cobble was tumbled and smoothed by streams that drained a range much older than the Santa Monica Mountains.
The title photo is from this morning’s run of the Bulldog Loop.
The afternoon was full of Fall. Oak leaves danced in a cool breeze, their shadows producing a familiar speckled pattern of shadow and sun, shadow and sun.
I was running northeast along the margin of Lasky Mesa in Upper Las VIrgenes Canyon Open Space Preserve, enjoying the Fall weather and smoke-free sky. I’d just passed a valley oak along the dirt road, when a thought bubbled up from my subconscious and asked, “Did you see what I saw in that tree?”
I stopped, turned around, and walked the few steps back to the oak tree.
Just feet from the road, partially camouflaged by oak leaves and shadows, was a red-tailed hawk. It seemed surprised, if not indignant, to have been discovered. I was equally astonished to have seen the bird.
The pattern of its plumage now made perfect sense. The hawk had been nearly invisible while feet away and in plain sight. I took one more photo, and then left the bird to its reverie.
I smiled as I ran down the road, and wondered if this was the same hawk that had buzzed me in Red-tailed Hawk Encounter.
Update November 14, 2020. Was near the spot where the encounter described above occurred and photographed a red-tailed hawk with a small rodent it had just killed. Since it’s in the same area, it may be the same bird.
Hidden away in the central highlands of Lasky Mesa, and not found on current maps, the “lake of the four hills” is shrouded in mystery.
Perhaps the result of earth movement or some other upheaval, the hills and lake seemingly appeared overnight. They are the latest in a series of perplexing formations to suddenly materialize on the site.
