Ahmanson Trailhead Rattlesnake

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 Southern Pacific rattlesnake at the Ahmanson Ranch trailhead.

Surprisingly, this was the first rattlesnake I’ve seen this year at Upper Las Virgenes Canyon Open Space Preserve . I’ve seen numerous gopher snakes, a couple of California kingsnakes, a California whipsnake, and the tracks of many rattlesnakes, but no actual rattlesnakes. Others have described various rattlesnake encounters at Ahmanson — one friend saw three on one ride!

Note: Most of these snakes were old enough to have survived the November 8, 2018, Woolsey Fire.

California Fuchsia Along East Las Virgenes Canyon Road

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.

As a result of the wet 2018-19 rain season, and somewhat cooler than normal summer, California fuchsia is especially abundant this Fall, with some exceptional displays along local trails.

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.

Weekday wildflowers are flowers I’ve encountered during 2019 on weekday runs from the Victory Trailhead of Upper Las Virgenes Canyon Open Space Preserve (formerly Ahmanson Ranch).

Upper Las Virgenes Creek Still Flowing in Mid-July

Upper Las Virgenes Creek, July 17, 2019.

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.

Humboldt Lilies in Upper Las Virgenes Canyon Open Space Preserve (Ahmanson Ranch) on June 19, 2019.

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.

The Humboldt lily and a few other wildflowers have been added to my Weekday Wildflowers slideshow. These are wildflowers photographed on weekday runs from the Victory Trailhead of Upper Las Virgenes Canyon Open Space Preserve.

From a run this May in Upper Las Virgenes Canyon Open Space Preserve (Ahmanson Ranch).

Normal rainfall for May at Downtown Los Angeles (USC) is 0.26 inch. This year Los Angeles recorded 0.81 inch in May, according to the NWS .

It was definitely wet and cool! Nineteen days were partly cloudy to cloudy. Ten days recorded at least a trace of rain. The average high was 70 degrees.

Oddly, during our recent drought, above normal May rainfall totals were recorded in 2011 (0.45 inch), 2013 (0.71 inch), and 2015 (0.93 inch). The most rainfall recorded in May at Los Angeles was 3.57 inches in 1921.
