This time of year, I’m often “racing the sun” on my afternoon runs. Especially on longer runs, when the additional miles quickly consume any remaining daylight. There are benefits. Colorful sunsets are just one of them.
Tuesday’s run was one of those longer runs — from the Victory Trailhead of Upper Las Virgenes Canyon Open Space Preserve (Ahmanson Ranch) to Cheeseboro Canyon and back. One of the reasons for doing this particular run was to follow up on the reemergence of water in upper Las Virgenes Creek. As Fall has progressed, there has been a notable increase in the size and number of pools, and the amount of water in the creek. I’ve observed this in the Fall before, except during periods of drought.
The comparison below shows a crossing of upper Las Virgenes Creek about one-third mile north of the junction of Las Virgenes Canyon and East Las Virgenes Canyon. It shows the intriguing reemergence of water in this reach of the creek, despite a dry Summer, and — as of Tuesday — meager Autumn rainfall. The increase in water in the reach seems to have resulted from seasonal reductions in daylight, temperature, evaporation, plant transpiration, and other factors.
Update October 22, 2019. A run over to upper Las Virgenes Creek supported the 0.46 inch of rain reported by the Cheeseboro RAWS on October 20. The ground appeared to have absorbed more rain in the Las Virgenes Canyon area, compared to the area near the Victory Trailhead. It also looked like the amount of water in the creek bed had increased.
Update October 21, 2019. The Cheeseboro RAWS, on the ridge just west of upper Las Virgenes Creek, recorded 0.46 inch of rain on October 20, the day after this run. Today, I’ll be running out that way again to see how the rain affected the creek.
I pressed the START/STOP button on my Garmin watch and started to walk over to the horse/hiker entrance at the Victory Trailhead of Upper Las Virgenes Canyon Open Space Preserve (Ahmanson Ranch). This “end of an Ahmanson run” routine is something that I repeat around 150 times a year. It’s so routine, it’s rote. I’m not thinking about rocks or ruts, or how far I have to go. It’s a time I can relax and reflect on the run, the weather, or whatever.
Continuing toward the trailhead entry, I pulled the water bottle from my pack. Lifting my head to take a drink, and still on auto, I began to step over the first of two large wooden beams forming the entrance.
Some primitive, protective mechanism recognized the threat before I did, and I stopped mid-stride. Then it registered — a sizable Southern Pacific rattlesnake was undulating through the boxed-in area between the two beams of the entryway.
Moving quickly through the entry and into the grass, the snake barely reacted to me. With single-minded resolution, it continued on a beeline toward the brushy area near the trailhead. A single shake of its rattle was all the bother I was worth. Here’s a short video of the rattlesnake.
If the wildflower is red, the season is Fall, and you are in Southern California, the flower is probably California fuchsia. You might also find there is a hummingbird feeding on the “hummingbird trumpets,” or hovering nearby, watching over its flowers.
I’ve added California fuchsia, and a few other flowers that are blooming this Fall, to my Weekday Wildflowers slideshow. These are wildflowers photographed this year on weekday runs from the Victory Trailhead of Upper Las Virgenes Canyon Open Space Preserve.
The most recent additions to my Weekday Wildflowers photo album include two non-native wildflowers seldom seen at Ahmanson Ranch — black-eyed Susan (Rudbeckia hirta) and bachelor’s button (Centaurea cyanus).
Both were found along the Lasky Mesa Trail near the dry streambed of East Las Virgenes Creek. They likely escaped cultivation or were part of a seed mix scattered in the area.

Following our five year drought, Downtown Los Angeles and many neighboring areas recorded above-average rainfall in two of the last three rain years. This has had obvious and observable effects on the area’s plants and animals and aided in the ongoing recovery of habitats affected by drought and wildfire.
This is the first time since the Summer of 2011 that there has been flowing water in upper Las Virgenes Creek in mid-July at the crossing near the Cheeseboro connector. It’s just a trickle, but keep in mind that during some of the drought years, this section of upper Las Virgenes Creek never flowed.
Update November 19, 2019. Increased surface water and pooling in Upper Las Virgenes Creek. See the post Running Into Fall.
Update August 28, 2019. The surface flow of Upper Las Virgenes Creek near the Cheeseboro connector is down to a bare trickle and some small pools.
Update August 7, 2019. Upper Las Virgenes Creek is still trickling.
Notes: In rain year 2016-17 Downtown Los Angeles (USC) recorded 19.00 inches of rain from July 1 to June 30, and in 2018-19, 18.82 inches. During the intervening rain year, 2017-18, only 4.79 inches was recorded.
Although I’d photographed them here before, it is still a bit startling to find Humboldt lilies on a hot, dry, dusty run in Upper Las Virgenes Canyon Open Space Preserve, aka Ahmanson Ranch. The vibrant orange blossoms stand out against the mix of muted greens, grays and straw-yellows of the oak woodland and chaparral and are hard to miss.
