Farewell-to-Spring in Upper Las Virgenes Canyon Open Space Preserve

Farewell-to-Spring found in Upper Las Virgenes Canyon Open Space Preserve in June 2023

An unusually wet rain season not only increases the population of many wildflowers, it can produce wildflowers not usually seen in an area.

The Farewell to Spring (Clarkia amoena) pictured above was one of very small population found in Upper Las Virgenes Canyon Open Space Preserve (aka Ahmanson Ranch) in June 2023. The California native is much more common in the Bay Area and coastal Northern California. It probably found its way to Ahmanson by way of a local garden.

This year’s bloom of Elegant Clarkia (Clarkia unguiculata) in Upper Las Virgenes Canyon Open Space Preserve (aka Ahmanson Ranch) is even more widespread and lavish than it was in Spring 2020. It’s virtually impossible to do a hike, run, or ride at Ahmanson Ranch and not see the stalks of the oddly-shaped, 4-petaled, pink-purple flowers.

As in 2020, Purple Clarkia (Clarkia purpurea) is also widespread. Not as common at Ahmanson Ranch is another member of the Evening Primrose Family, Shredding Primrose (Eremothera boothii). It can be found along the Edison service road near the Las Virgenes Trailhead.

After the Bobcat Fire: Running the ANFTR 25K Course

On June 1, Angeles National Forest reduced the size of the Bobcat Fire Closure, opening up most of the upper West Fork San Gabriel River area. Curious to see how the West Fork area is recovering from the Bobcat Fire, today I ran a slightly shortened version of the ANFTR/Mt. Disappointment 25K course.

Since the Mt. Wilson parking lot is usually closed until mid-morning, this morning’s run started and ended at a small turnout near the top of the Kenyon Devore Trail on the loop road on Mt. Wilson. The ANFTR Trail Races start at the main Mt. Wilson parking lot.

I’d recently done the San Gabriel Peak and Bill Riley Trails and knew they were in reasonable condition. And I’d read that AC100 Trail Work Teams led by Gary Hilliard and Ken Hamada had cleared the Gabrielino and Kenyon Devore Trails earlier this year. So, I didn’t expect to have a repeat of the epic fallen-tree obstacle course that I experienced doing this course in 2020.

Here’s a slideshow of what I found.

Red Box – Bear Canyon – Switzer’s Loop – Memorial Day Weekend 2023

The Red Box – Bear Canyon – Switzer’s Loop trail run is a favorite I’ve enjoyed doing for many years. Part of its attraction is the isolated, backcountry feel of Bear Canyon, particularly between Tom Sloane Saddle and Bear Canyon Trail Camp. It’s worth spending a few minutes at the old cabin site in the upper canyon to contemplate a lifestyle from an earlier century.

The descent of Bear Canyon is always adventurous in some way. Based on what I’d been seeing on other trails this year, I’d expected upper Bear Canyon to be a mess. I had braced myself for downed trees, washouts, and overgrown, hard-to-follow sections of trail.

But just a few minutes below Tom Sloane Saddle, a tree blocking the trail had been cleared, and the saw cuts were fresh! As I worked down the trail, I was excited to find more trailwork had been done. Branches or trees that had fallen across the trail had been cut. Some overgrown sections of trail had been trimmed. One washed-out section of trail looked like it had just been repaired. Someone had even trimmed a little of the poison oak that is so common along the trail.

As I discovered when I encountered them lower in the canyon, the Bear Canyon Trail Crew had been hard at work, and they were working in the canyon again today!

The last time I was in Bear Canyon (April 2021), the creek had been nearly dry. This year there was plenty of water and plenty of stream crossings. Unlike several recent runs, I had my poles and was able to keep my shoes and socks mostly dry.

I had debated whether to do this loop on Memorial Day Weekend. It passes through Switzer’s Picnic Area, one of the most popular day-use areas in Angeles National Forest. Many visiting Switzer’s do the hike down the Gabrielino Trail to see Switzer Falls, and many of those continue down the Bear Canyon Trail to the area below the falls.

Today, the two-mile stretch from below the falls to Switzer’s was as busy as expected. One issue I hadn’t anticipated was that some stream crossings were backed up like the Hillary Step on Everest. Other than wading, there was usually only one “dry” route across the stream. At one busy crossing, a hiker — clutching a dog under each arm — deftly balanced across a sequence of slippery rocks and branches, keeping his and his charge’s feet dry.

Once past Switzer’s, things returned to normal. From Switzer’s, it’s about 4.5 miles up to Red Box, with an elevation gain of about 1350′. I had been on this section of the Gabrielino Trail about a month before and was curious to see if a mass of fallen trees blocking the trail had been removed.

The trees still needed to be cleared — Forest Service rules require a qualified sawyer to do that kind of work — BUT the remaining 2.5 miles of trail to Red Box were being trimmed and cleared by several dozen members of the Mt. Wilson Bicycling Association. I wondered why I wasn’t seeing any mountain bikers on the trail — they were all working on it!

The bloom of Yellow Mariposa Lily along the Chumash Trail in Simi Valley has been extraordinary this year. Above, it is pictured with Golden Stars.

Among the multitude of wildflowers blooming along the trail this May were the showy Butterfly Mariposa Lily and intensely blue Parry’s Larkspur.

Running, Hiking and Riding Just Got a Little Easier in Some Parts of Ahmanson Ranch

Equipment used to scrape and grade dirt roads in the area of upper Las Virgenes Canyon.

Dirt roads used to service gas pipelines that pass through Ahmanson Ranch have recently been scraped and graded.

Scraped and graded section of East Las Virgenes Canyon Rd about two miles west of the Victory Trailhead.

The work was sorely needed. In the wake of our very wet rain season, in some areas the mustard was 8 feet tall and roads were rutted and damaged.

All of the scraped roads are in the western part of Ahmanson, primarily in and near upper Las Virgenes Canyon. Some very welcome weed-cutting was previously done along the roads in other parts of the open space area.

(Officially named Upper Las Virgenes Canyon Open Space Preserve, most users refer to the open space area as Ahmanson Ranch or simply Ahmanson.)
