Following more wet weather, I was back on the Backbone Trail and running in the direction of Mishe Mokwa from the Encinal Canyon trailhead. But this time, instead of going to Mishe Mokwa, I planned to do an out-and-back run to Triunfo Peak (2658′).

Whenever I’ve been on the Yerba Buena segment of the Backbone Trail, I’ve been curious about this peak. Situated on the crest of the Santa Monica Mountains, east of Sandstone Peak, it seemed like it might be an outstanding viewpoint, and I wasn’t disappointed.

About a half-mile up the Backbone Trail from the Encinal Canyon trailhead, I was surprised to be able to get a glimpse of the peak. Historic topo maps labeled the fire lookout on Triunfo Peak as “Triunfo Lookout” and now the peak is often referred to by that name.

It was another beautiful morning on the Backbone Trail. A chilly 39 degrees at the trailhead, it warmed quickly as I ran up the trail toward Mulholland Highway and then Etz Meloy Mtwy fire road. The bloom of bigpod Ceanothus was in full swing, and the lilac blooms of hairy-leaved Ceanothus were already following suit.

Thin high clouds veiled the sun and muted the scene as I descended the Backbone Trail to Yerba Buena Road. To the west Triunfo Peak/Lookout, Boney Mountain, and Sandstone Peak filled the skyline, their rocky prominences inviting further exploration.

About two miles west of the Yerba Buena Road, a makeshift sign indicated where the trail to the peak could be accessed. In 40-50 yards the side trail led to Yellow Hill Fire Road — the old lookout service road. It had recently been cleared of brush. From the sign on the Backbone Trail, it was about three-quarters of a mile to the top of the Triunfo Peak, with an elevation gain of about 380 feet.

According to the Former Fire Lookout Sites Register and Fire Lookouts websites, the lookout on Triunfo Peak was established in the early 1930s and taken out of service in the late 1960s. A steel lookout tower originally on Blue Ridge in Angeles National Forest was first moved to Bodle Peak around 1930, then moved and reassembled on Triunfo Peak in 1935.

The photograph of the lookout tower when it was on Blue Ridge suggests the shrine-like concrete structure found on the summit of Triunfo Peak is the footing for the tower. Google Earth imagery shows a similarly-sized footing on Bodle Peak -— a square a little larger than eight feet on a side. The tower is  described  as having an “8×8 observation cabin.”

A short connector trail is being constructed on the wet/northwest side of Trunfo Peak. When the trail is complete, it will connect the Backbone Trail to Yellow Hill Fire Road, near the summit of Triunfo Peak. The new trail will enable those doing the Backbone Trail to climb Triunfo Peak and return to the Backbone Trail without backtracking.

Caught in a Thunderstorm on Rocky Peak

Rocky Peak Road is an exceptionally popular hiking and biking trail that starts at Santa Susana Pass, on the north side of the 118 Freeway. Regardless of the time of day or weather I ALWAYS see someone on this trail.

The plan for this afternoon’s run was to do an out and back on Rocky Peak Road to the top of the Chumash Trail (3.8 miles) or to Fossil Point (4.8 miles).

Another runner was finishing their workout as I started up the initial steep climb. Glistening in the warm sun, runoff from yesterday’s storm streaked some of the sandstone rocks, and ephemeral streams gurgled in the ravines and gullies.

Thanks to the sandstone geology, the dirt road wasn’t as muddy as most other local trails would be. Although heavily eroded from numerous Winter storms, it was still near the top of my list of places to run during periods of wet weather.

In the aftermath of yesterday’s storm the weather was spectacular. The temperature was warm enough to run in shorts and short-sleeves but still comfortable chugging up Rocky Peak Road’s steep hills. Puffy cumulus clouds filled the sky, creating postcard views at every turn.

More focused about getting up the hill than any weather concerns, I continued past the top of the Hummingbird Trail and through a gap in the rocks to a section of road with a good view of the San Fernando Valley and San Gabriel Mountains.

I’d been in a situation similar to this several times on Rocky Peak. As a storm moves east from Los Angeles, energy circulating around the low can sometimes result in “back-door” precipitation. In this scenario, clouds build-up over the mountains to the north and then drift over the San Fernando Valley, producing showers — and sometimes — thunderstorms.

But today’s scenario was a bit more complicated. A much larger area, extending east to the San Gabriel Mountains, was rapidly destabilizing. What had been a picturesque sky at the start of the run was now congested and ominous. The question wasn’t so much if it was going to rain, but if a thunderstorm was going to develop.

As I continued up the road, the sky darkened, the temperature cooled, and the wind became more gusty and fitful. A little chilly, I pulled on my arm sleeves. I laughed nervously as I mistook the roar of a passing jet for thunder. That was a jet, right?

When people say they are “doing Rocky Peak,” they are often referring to a high point on Rocky Peak Road that is west of the actual peak and about 2.4 miles from the trailhead. The final climb to this high point is a good one — gaining about 450 feet over three-quarters of a mile.

The road on this stretch is oriented in such a way that the terrain hides the view to the north. I was anxious to get to the top of the hill so I could get a better idea of what the weather was doing. As I worked up the road, I would occasionally feel the cold splash of a raindrop on one leg or the other.

Nearing the top, I thought, “I may get wet, but at least there’s been no thunder.” Within seconds of that proclamation, and as I reached the highest point, there was a long, loud, crackling peal of thunder.

One look at the sky and all thoughts of continuing to the Chumash Trail were gone. I turned around and started running down the hill, hoping to avoid the worst of the storm.

First one pea-sized hailstone hit the ground, then another, and then a sleety barrage of rain and hail poured from the sky. Instantly soaked, I shuddered as thunder echoed overhead and cold rain ran down my back. Muddy water flowed in rivulets down the sodden road and I cautioned myself to run fast, but not too fast.

I didn’t expect to outrun the storm, but hoped I might move to a part of it that was less intense. And that’s what happened. As I descended, the deluge gradually diminished. Most of the activity seemed to be behind me and a little to the east.

By the time I got down to the Hummingbird Trail, it was only sprinkling. The strong cell that had been over Rocky Peak had drifted southeast, and was now over the Porter Ranch – Northridge area.

National Weather Service Doppler Radar tells the story. At the start of the run there were scattered, mostly weak echoes. At 3:06 pm, as I was starting up the last long hill, a cell northwest of Rocky Peak was developing and drifting southeast. Over the next 16 minutes the cell continued to move southeastward and strengthen, and at 3:22 pm was over the Rocky Peak area. I turned around and started down as the cell moved into that area.

The cell over Rocky Peak continued to strengthen, and at 3:39 pm had drifted over the Porter Ranch – Northridge area. At 3:44 pm the NWS issued a Severe Thunderstorm Warning for Western Los Angeles County.

Here are a GOES-18 satellite loop and Doppler Radar loop that show the development and track of the Rocky Peak thunderstorm.

Trippet Ranch Loop, Musch and Garapito Trails – February 2024

It’s uncommon to have back-to-back Rain Years with 20+ inches of rain in Los Angeles. During Rain Year 2022-2023, Downtown Los Angeles (USC) recorded 28.4 inches of rain — about two times normal. This rain year Los Angeles has already had about 21 inches of rain, so another big year is in progress.

Curious to see how the trail conditions compare to last year, on February 17th and 25th I ran the Trippet Ranch Loop in Topanga State Park.

The big surprise was that the fire roads on the loop — Fire Road #30, Eagle Springs Fire Road, and a short section of Eagle Rock Fire Road — generally fared better than last year. Fire Road #30 had some damage along it’s shoulder, but I did not see the numerous mudslides along these roads like last year.

The news on the trails was divided. One of the more unusual events occurred where the Garapito Trail crosses the east fork of Garapito Creek. A mudslide from a gully on the northwest side of the creek crossed the creek, and left a pile of debris on the trail. The stream may have been dammed by mud and debris for a short time. Farther up the trail, about a half-mile from Eagle Rock Fire Road, a section of the trail collapsed in a slide.

The Musch Trail was very muddy and wet in the usual places. There were a couple of slides along the trail, but all things considered, the trail was in OK shape. The Bent Arrow Trail remains closed as a result of previous storm damage.

Last year, the bloom of bigpod Ceanothus was well underway in early January. This year the bloom began about a month later but is now happening in a big way. Greenbark Ceanothus is also starting to bloom. Some peonies were blooming on an east-facing slope of the Garapito Trail, and a Fuchsia-flowered gooseberry was in bloom near Fire Road #30.

Here are some photos taken on these two runs.

Rainy Season Trail Running on the Backbone Trail

The Backbone Trail between Encinal Canyon and Mishe Mokwa is one of the must-do sections of the 68-mile trail. Engineered to be multi-use, this exceptionally scenic stretch of the Backbone Trail is popular with riders, hikers, and runners alike.

It’s also a pretty good place for a trail run after rainy weather like we’ve had this February. Although the parking lot at the Encinal Trailhead was quite wet this morning, the  Backbone Trail was in decent shape most of the way to the Mishe Mokwa trailhead. There were a few muddy and wet spots, but it was generally easy to work around them. And I didn’t have to change my shoes before driving home.

The out & back run worked out to about 21-miles, with a surprisingly moderate gain/loss of about 2500′. The weather and visibility were excellent. Striking rock formations and the Channel Islands could be seen from one side of Etz Meloy Mtwy fire road, and snow on Alamo Mountain and other Ventura County peaks from the other side.

On the way back, as I was working up the long hill on the northwest side of Triunfo Lookout, a descending mountain biker commented that a large group of bikers were at “the corner.” The overlook at this prominent switchback has a wide-ranging view of Mishe Mokwa, Boney Mountain, and Sandstone Peak, and some prefer to turn around here. This variation is about 3.5 miles shorter (round-trip) than dropping down into the canyon and going all the way to Mishe Mokwa.

After January 2023’s torrential rains and Hurricane/Tropical Storm Hilary’s drenching in August, here we are again, experiencing record rainfall.

Over the first six days of February 2024, Downtown Los Angeles recorded 10.2 inches of rain. That’s almost three-quarters of L.A.’s normal ANNUAL rainfall in just a few days and the wettest start to February on record! Some stations in the Santa Monica and San Gabriel Mountains recorded even more — over 13 inches in some locations!

How much did it rain at Ahmanson Ranch (Upper Las Virgenes Canyon Open Space Preserve)? Unfortunately the Remote Automated Weather Station (RAWS) on a hill between Upper Las Virgenes Canyon and Cheeseboro Canyon hasn’t been accurately measuring precipitation. A citizen weather station (KCAWOODL130) near the Victory Trailhead at Ahmanson Ranch recorded over 11 inches from February 1 – 6. Another station near Cheeseboro Road in Agoura (KCAAGOUR41) recorded over 9 inches.

Whatever the amount, it was a lot. Here is a short video, from a run at Ahmanson Ranch on February 7, 2024, to check out the conditions and creeks.

As I write this, more wet weather is forecast to affect the Los Angeles area, beginning sometime over the weekend of February 17-18. We’ll see!

Update Friday, February 16, 2024.  Latest forecast for Los Angeles area suggest the rain may hold off until Sunday night or Monday.

Running to the Temescal Canyon Cascade From the Top of Reseda (Two Ways)

first published & last updated

Temescal Canyon Cascade

The Temescal Canyon “waterfall” is an immensely popular cascade, most often accessed from Temescal Gateway Park using the Temescal Canyon Trail. Judging from the number of people on the trail, a loop incorporating the Temescal Canyon and Temescal Ridge Trails is also very popular.

Even though many refer to it as a waterfall, it’s not a dramatic river-wide fall, such as Nevada Fall in Yosemite. Picture a Japanese garden with a gurgling little stream, cascading down through rocks into a pool, surrounded by an artistic arrangement of plants and trees. There’s even the requisite bridge to complete the composition. It would be meditative if it were not so popular.

Over the past few weeks, I’ve run from the Top of Reseda (Marvin Braude Mulholland Gateway Park) to the Temescal Canyon Cascade two ways — a 15-mile out-and-back and a 21-mile loop.

The out-and-back route from the Top of Reseda was one of those “I’ll just go a little bit farther” runs. It had rained the day before and the NWS forecast called for a chance of showers in the morning and then showers likely in the afternoon.

With the weather unsettled, I didn’t have a particular plan in mind. When I started the run, it looked like it might rain at any time, so I decided to run to Temescal Peak, and then play it by ear from there. Once on Temescal Peak, the weather seemed to be holding, so I continued to Temescal Lookout. From the Lookout, Green Peak was just a “little bit further,” and in a few minutes, I was standing on top.

I continued to be drawn down Temescal Ridge in this fashion, and before I knew it was at the junction of the Temescal Ridge and Temescal Canyon Trails. From there, it was only a half-mile down to the cascade.

Two weeks later, I was back at the Top of Reseda. It had rained an inch and a half in Downtown Los Angeles a couple of days before, and a well-advertised multi-day rain event was forecast to begin the following day.

The previous weekend, a friend and I had climbed/run to Sandstone Peak from Wendy Drive. Temps in the sun reached into the 80s, and maybe I talked too much and ate and drank too little. On the way back, I hit the wall near the turn onto the Upper Sycamore Trail.

This morning, I had no idea how my legs were going to feel. My loosely defined plan was to run out the Rogers Road segment of the Backbone Trail from the Top of Reseda and see. If the legs held up, I’d continue to Will Rogers State Historic Park. If not, maybe I’d do Goat Peak or something else.

The temperature was in the 40s most of the way down to Will Rogers. With the cool weather, it seemed my running was back to normal. From Will Rogers, I headed over to Rivas Canyon, where I found Sierra Club volunteers hard at work on the Rivas Canyon Trail. This enjoyable trail links Will Rogers to Temescal Canyon and is a key part of the loop.

Once down in Temescal Canyon, there was a constant stream of hikers going up the Temescal Canyon Trail to the cascade. With the recent rain and good weather, the cascade had more water and more people than on the run in January. A large group rested near the bridge, and hikers hustled and bustled up and down the trail. The little cascade gurgled and burbled in the morning sun, glistening bubbles popping up beneath the plunging stream and then disappearing as they wandered downstream.

Soon, I was chugging up the trail toward its junction with the Temescal Ridge Trail, retracing my steps from two weeks before.
