Revitalized Valley Oak at Ahmanson Ranch

Sunlit valley oak in Upper Las Virgenes Canyon Open Space Preserve (Ahmanson Ranch)

Revitalized by December’s copious rainfall and temperatures in the mid-80s in February, this valley oak at Ahmanson Ranch has produced a lush crown of new leaves.

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

The cumulus cloud towered overhead, its size accentuated by a lone oak on the skyline. An extraordinary series of December rainstorms were finally over. The year 2021 would end with Downtown Los Angeles (USC) having recorded the third highest amount of December rainfall on record.

I was running from the Victory Trailhead of Upper Las Virgenes Canyon Open Space Preserve (aka Ahmanson) to Las Virgenes Canyon. With about 5 inches of rain in the area over the past two days, I was curious to see how upper Las Virgenes Creek was flowing.

Here are a few photos from the December 31st trail run and several other trail runs at Ahmanson over the past couple of wet weeks.

Update January 4, 2022. Did the Garapito Trail again this weekend as part of a longer run through Santa Ynez Canyon. The debris from the fallen oak tree was much easier to get through this time. Some people coming down the trail after me had a small saw, and said they were planning to work on it.

Update December 31, 2021. It turns out that a lot more rain was on the way! Los Angeles recorded 9.46 inches of rain this month, making it the third wettest December on record, going back to 1877. This puts Los Angeles at 10.40 inches for the Rain Year to date, which is about 237% of the normal.

It had rained the past three days, including Christmas. Today was the 26th, and Downtown Los Angeles (USC) had recorded nearly 150% of the rainfall normally recorded in December. And more was on the way.

I clicked START on my Garmin as I passed the gate at the Top of Reseda. It was about twenty minutes before sunrise. The temperature was around 40 and the eastern sky was brightening with the advancing sun. As I worked up the initial trail to dirt Mulholland, thousands of lights twinkled across the San Fernando Valley.

The chaparral was soaked with overnight rain; and befitting the Holiday season, was ornamented with thousands of silvery water drops.

I took my usual route, turning off Mulholland onto Fire Road #30, and then following it to the Hub. From the Hub, Eagle Springs Fire Road led down to Eagle Springs, then beneath the sunlit face of Eagle Rock to Eagle Rock Fire Road and the top of the Musch Trail. In the Palisades Fire burn area there was some significant erosion along the fire road where the runoff wasn’t controlled.

I’d be doing the Musch Trail later in the run, but for now continued down Eagle Springs Fire Road toward Trippet Ranch.

Mud — slippery, cake-on-your-shoes mud — isn’t normally much of an issue until past the Musch Trail and on the steeper downhill that leads to the top of the Santa Ynez Trail and Trippet Ranch. Today there were some slippery spots, but it wasn’t too bad. Remarkably, I didn’t see anyone until I reached the Trippet Ranch parking lot.

My return route from Trippet Ranch was mostly on trails, beginning with the Musch Trail. There are usually a few muddy sections on the Musch Trail after a good rainstorm. Today, one wet, muddy section of trail was steaming in the morning sun. Once I was on the steep climb up to Eagle Rock Fire Road, most of the significant mud was left behind.

At the top of the Musch Trail, I turned left on Eagle Rock Fire Road and worked up past Eagle Rock and over to the top of the Garapito Trail. I run this trail often, and know it well. Winding down through decades-old chaparral, I became lost in thought, immersed in the outdoor experience, and enjoying every aspect of the trail.

That was why it was such a shock when, at the bottom of the mile and a half descent, the trail suddenly ended in a wall of brush.

That couldn’t be. Had I somehow turned onto a use trail? Nope, I was on the right trail.

That’s when I noticed the “brush” was the top branches of a large oak. The fallen tree had COMPLETELY blocked the trail. I took a quick look around for an alternate route and didn’t see anything obvious. Working through the mishmash of foliage and branches was a bit like bushwhacking through dense manzanita. With some effort, and some rock climbing moves, I eventually emerged on the other side of the mass. The fallen tree was part of an old, multi-trunked oak that has been collapsing over a period of weeks.

The remainder of the run was uneventful, but enjoyable. Continuing up the Garapito trail to Fire road #30, I crossed the fire road and picked up the Bent Arrow Trail. This connects to dirt Mulholland, which leads west to the Top of Reseda.

Rabbitbrush Along the PCT Near Mt. Hawkins

Rubber rabbitbrush (Ericameria nauseosa) along the PCT, near Mt. Hawkins

From mid Summer into Fall, the vibrant yellow flowers of rabbitbrush add a refreshing hit of color to the greens, grays, and browns of the San Gabriel Mountains.

The title photo was taken along the PCT, at an elevation of about 8600′, near Mt. Hawkins. The area was burned in the 2002 Curve Fire. Here, and elsewhere in the burn area, new trees — now in their teens — are slowly replacing some of the trees lost in the fire.

This 17 mile trail run and hike is a longer version of the Inspiration Point to the Pine Mountain Juniper adventure run. Additional details and photos can be found in that post.

The adventure combines a seven-mile run on the PCT along Blue Ridge with a strenuous 1.5 mile, 1500′ climb up the North Backbone Trail to the summit of Pine Mountain (9648′). The Pine Mountain Juniper, estimated to be 800-1000 years old, is found at the 9000′ level of the North Backbone Trail.

On the way out I was glad to see the PCT had been rerouted around a steep, rocky stretch of trail below Mountain High West’s snow-making pond. I stayed on the PCT except for a very short section of dirt road between the top of the Acorn Trail and the overlook of the huge Wright Mountain landslide scar. The single track is more pleasant, and I didn’t have to worry about vehicles or their dust. I left the PCT when I was directly above the North Backbone Trailhead. A short path descended to the road.

The North Backbone Trail was as steep as it has always been. It’s not a constructed and maintained trail, but one that has evolved through use. Stretches of it are very steep, loose and rocky. The tree on Point 8555 that was struck by lightning in 2006 has finally fallen. There must be a lot of lightning activity here because a nearby pine had been recently struck by lightning.

The North Backbone Trail seems to be getting more attention these days. This adventure could be extended to include Dawson Peak and Mt. Baldy. A similar route was part of the 44-mile Big Pines Marathon — possibly the first mountain ultra in the U.S.
