A Morning Thunderstorm, Debris-Covered Trail, Fast-Paced Fire Road, and Tough Climb on the ANFTR 25K Course!

As I drove east on the 210 Freeway, a long bolt of lightning erupted from high in the clouds and pierced the valley below. The thunderstorm near Mt. Lukens looked spectacular. It was backlit by the rising sun, and intermittent lightning flashed against its dark gray clouds.

Theoretically, I was headed to Mt. Wilson. It was July. It was hot. It was time to get on the ANFTR/Mt. Disappointment race course! But was that going to be a good idea? A slight chance of a thunderstorm was forecast for the afternoon and already there was an active storm right in front of me.

The Angeles National Forest Trail Races (aka Mt. Disappointment) is a popular event usually run in the heat of Summer after the Fourth of July. Because of the pandemic, Bobcat Fire, and trail and road closures, the race has been on hiatus since 2020, but a new race date appears to be in the works!

Another ragged bolt flashed horizontally across the clouds. The cell looked isolated and appeared to be moving to the north. I decided to take a chance and bet that the morning storm was a quirk. Still, it suggested a real possibility of a thunderstorm later in the day.

About the time I passed Trail Canyon on Big Tujunga Canyon Road, it started to rain, and the rain continued much of the way to Red Box. The activity was actually more extensive than the cell near Mt. Lukens — a band of thunderstorms had swept through the San Gabriel Mountains between Mt. Lukens and Mt. Wilson.

Mt. Wilson Road was still wet as I started down the first leg of the ANFTR/Mt. Disappointment 60K/50K/25K courses. If you have to run on pavement, running downhill on super-scenic Mt. Wilson Road after a thunderstorm is about as good as it gets! The cleansed atmosphere and vivid smells in the wake of the storm were remarkable — as were the views down into the canyon of the West Fork San Gabriel River.

This morning, I was doing the 25K course, but all the distances follow the same route to Red Box. They start by running down Mt. Wilson Road to Eaton Saddle and then following Mt. Lowe Fire Road through Mueller Tunnel to Markham Saddle and the San Gabriel Peak Trail. The San Gabriel Peak Trail leads up to the Mt. Disappointment service road and, surprisingly, the high point of the 60K/50K/25K courses. This stretch of service road is higher than the start/finish on Mt. Wilson!

Even if you have run a trail many, many times — and think you’re familiar with it — sooner or later, you’re going to encounter something you didn’t expect. From the Mt. Disappointment service road, the ANFTR/Mt. Disappointment courses turn onto the Mt. Disappointment/Bill Riley Trail. After the first couple of switchbacks, there were an increasing number of cut limbs on the trail. Initially, the cuttings were not much of an issue, but became worse as I continued down the trail.

Partway down, I encountered two very upset hikers who had lost the trail. They had just decided to leave the trail and hike on the service road. They cautioned me that the section where they had problems was just below. They weren’t kidding. I’ve done this trail innumerable times and at one point also had difficulty locating it. I had to wade through an expanse of cuttings to stay on the trail.

I’ve been on trails impacted by forest thinning projects before. The crews that worked on those projects at least made an effort to keep the trails clear. No such attempt was made here — the cuttings were left where they fell, and if that was on the trail, too bad!

It was a relief to get off the Mt. Disappointment/Bill Riley Trail and down to Mt. Wilson Road and Red Box.

Unlike last year, Rincon-Red Box Road was in great shape. It was so well-graded that a Prius might have been able to drive down to West Fork. Much of the 5.5 miles down to West Fork are in full sun, so the temperature has a substantial impact. In the 2019 ANFTR/Mt. Disappointment 50K, the thermometer on my pack read about 80 degrees. In the 2017 50K, the temp on the same stretch was about 100 degrees. Today, it was around 90.

Whatever the temperature, there are excellent views down the West Fork and of the Mt. Wilson area. The towers on Mt. Wilson always look tantalizingly close, and the climb up Strayns Canyon doesn’t look that bad. (Ha!) Like last year, there were four or five creek-like crossings of the West Fork San Gabriel River.

The area around the spring at West Fork was a bit overgrown, but a trampled path through the grass below the cistern led to the outflow pipe. I refilled my hydration pack and drank my fill before setting off on the Gabrielino Trail. With the temperature in the sun at West Fork around 95, I should have spent more time at the spring cooling down.

It’s only about 1.6 miles from the spring to where the Kenyon Devore Trail forks left off the Gabrielino Trail, but it often seems longer. Probably because I’m anticipating the turnoff and don’t want to miss it. This morning, it was also the hottest stretch on the course, with the temperature in the sun topping out at around 100 degrees.

Based on some recent runs, I expected the Poodle-dog bush on this stretch to be a problem, but most of the Poodle-dog bush had been trimmed or was wilting. It wasn’t the only thing that was wilting. Shortly after turning off the Gabrielino Trail and onto the Kenyon Devore Trail, the combination of heat and humidity hit me like the proverbial brick. I had to back off the pace.

Not long after that, I was startled by a runner coming up behind me. It turned out to be another runner from the West San Fernando Valley! Charlie was training for UTMB and putting in a tough 27-mile, 8700′ gain day. We had a great conversation about races, running, and adventures in the mountains. Despite the heat, he was moving well and soon disappeared up the trail.

It’s about a half-mile to the top of the Kenyon Devore Trail!

I continued chugging up the trail, noting familiar features as I climbed higher and higher. Eventually, the white dome of the Hooker 100 inch Telescope came into view, and I knew I just about done!

As I worked up the final half-mile of trail, I could see only a couple of  isolated build-ups of cumulus clouds. One was over the desert  and the other was to the east near San Gorgonio.  The sky over Mt. Wilson was mostly clear.

Here’s a high-resolution, interactive, 3D-terrain view of the Mt. Wilson – Red Box – West Fork – Kenyon Devore Loop. The loop is a slightly shorter version of the ANFTR/Mt. Disappointment 25K.

Fog, Flowers and an Ingenious Spider on the Trippet Ranch Loop

In their forecast discussion for today, the NWS Los Angeles Oxnard commented, “A long-lasting and extreme heatwave will continue across the region, and especially the interior…” The high temperature was expected to range from 105 to 115 across the interior valleys, mountains and deserts.

I was doing the Trippet Ranch Loop from the Top of Reseda. The highs on the San Fernando Valley side of the Santa Monica Mountains were expected to be in the 90s. But keep in mind that’s essentially the temperature in the shade. In full sun, the temperature could be 10 to 15 degrees higher. When I reached the Hub, at 7:00 in the morning the in-the-sun temperature was already around 90 degrees.

Nearer the coast, temps were expected to be a little cooler. From the Hub, I could see why. A shallow marine layer had developed along the coast. A couple of miles later, as I neared Trippet Ranch, I descended into a bank of wonderfully cool fog. It wouldn’t last, but I enjoyed the coolness as I continued down to Trippet Ranch and around to the Musch Trail.

I hadn’t run very far on the Musch Trail when I came across a remarkable spider web. The spider had ingeniously bowed a flexible stalk of tall grass to build its web. This solution avoided having to span the web between two stalks. I also wondered if the added tension would make the web more efficient.

At Musch Camp, I topped off my water bottle and then continued working up the trail. Near a still-seeping vernal creek, a speckled-orange Humboldt lily bloomed brightly in a patch of poison oak.

From the camp, the Musch Trail climbs about 400′, in a bit over a mile, to the junction of Eagle Rock and Eagle Springs Fire Roads. A left turn here leads past Eagle Rock to the top of the Garapito Trail.

Other than the Bent Arrow Trail—which remains closed—the Garapito Trail is the “End of Reseda” trail most impacted by our back-to-back wet rain seasons. At times, washouts, debris flows, slides, fallen trees, and vigorously growing chaparral plants have made the trail nearly impassable. The Santa Monica Mountains Task Force worked tirelessly over the Winter to restore the trail.

Of course, the rain that caused all the problems on the Garapito Trail has also resulted in numerous wildflowers along that trail. Today, some of the most prominent were scarlet larkspur, scarlet monkeyflower, Indian pink, and Plummer’s mariposa lily. And, Garapito Creek was still trickling in July!

Out and Back Trail Run from Islip Saddle to Mt. Baden-Powell – July 2024 Update

Mt. Baden-Powell from the PCT near Throop Peak.
Mt. Baden-Powell from the PCT near Throop Peak.

Update July 22, 2024. The Poodle-dog bush along the PCT near Islip Saddle has been cleared by Gary Hilliard and the AC 100 Trail Team!

When I reached the summit of Mt. Baden-Powell (9,399′), it was empty, save an opportunistic raven who was evaluating the chances that the Larabar I was eating might fall to the ground.

On top, the heat of the strong Summer sun was offset by a cooling breeze. There was still a few thin ribbons of snow in the chutes on Mt. Baldy. With the excellent visibility, San Jacinto Peak could be seen in the notch between Mt. Baldy and Dawson Peak, and San Gorgonio Mountain was sharply visible to the left of Pine Mountain.

Other than a few people at Little Jimmy hike-in camp, I saw no one on the way up from Islip Saddle. A quarter-mile from the trailhead, there was an astonishing display of Poodle-dog bush along the PCT. In 2011, when a large part of Angeles National Forest reopened following the Station Fire, I developed an extensive rash after bushwhacking through Poodle-dog on overgrown trails. After that experience I’ve been more careful around the plant, and haven’t had a bad case since.

Trees were across the trail in a few places. Most were fairly easy to bypass, but a couple were “inconvenient,” such as this big log, about 0.75 mile east of Windy Gap.

As I worked up the switchbacks above the log, to the southwest I could see the observatory and towers on Mt. Wilson. As a result of the damage to Chantry Flat in the Bobcat Fire, Mt. Wilson was on the Angeles Crest 100 Mile course last year, and will be again this year. As the raven flies, Mt. Wilson was only about 16 miles away, but for someone running the AC100, the miles along its challenging course would total well over 50!

For several years I’ve been following the regrowth of conifers in four places along the PCT that were burned in the 2002 Curve Fire. What has been underscored in my informal study is a) trees take a long time to regrow, and b) frequent fires in an area are particularly devastating. Stand #1 (1.5 miles east of Islip Saddle on the PCT) was recovering nicely from the 2002 Curve Fire when it was burned in the 2020 Bobcat Fire. This comparison shows the result. The other three stands continue to recover well, with south-facing Stand #4, west of Throop Peak, growing particularly vigorously.

Ascending the final 400′ of gain on Baden-Powell’s west ridge, I was surprised to see a couple of small patches of snow remained on the north side of the ridge. The snowpack here was nowhere near as big as in 2023, but it was still pleasing to see that a little of the white stuff survived until July.

No out and back to Baden-Powell is complete without a quick stop at Little Jimmy Spring. Today, the water from spring was so cold it was painful to hold my hand in the water flowing from the pipe!

Hot Weather on the Three Points Loop

Approaching Waterman Meadow on the Three Points - Mt. Waterman Trail.
Approaching Waterman Meadow on the Three Points Loop around Mt. Waterman.

When Angeles Crest Highway opened between Upper Big Tujunga Road and Islip Saddle last Fall, I jumped on the chance to do the Three Points loop around Mt. Waterman. When in good condition and with good weather, the 20+ mile loop is one of my favorites. That day, the trail conditions could have been better.

Turn the clock forward to this Spring, and once again, road closures were limiting access to Three Points. Angeles Crest Highway was still closed between Red Box and Upper Big Tujunga Canyon Road, and the alternate route — Upper Big Tujunga Canyon Road — was “Only Open To Contractors, Residents, & Emergency Vehicles.” Recently, the Los Angeles County Road Closures website updated the status of Upper Big Tujunga Canyon Road to “Access Limited, Expect Delays.”

Excited to get back on the Three Points Loop, on Sunday I found myself motoring up Upper Big Tujunga Canyon Road, headed for the Three Points Trailhead. There were no problems or delays getting to Angeles Crest Highway, and I pulled into the Three Points parking lot at about 6:30 a.m.

Having done the Three Points Loop many times and in a variety of conditions, I didn’t think much about the difficulties on the loop in November. Like others that relish the outdoors, my brain is very good at shaping memories so as to emphasize the positive and downplay — or outright ignore — the negative.

I’d checked the weather — a Heat Advisory had been issued for the San Gabriel Mountains, and there was a chance of thunderstorms from a dissipating tropical storm. A key part of the loop, Cooper Canyon, has a rep for being hot. Much of the PCT on that stretch is on sparsely-forested, south-facing slopes. My thought was that maybe there would be enough clouds to take the edge off the heat.

Nope! The in the sun temperature in Cooper Canyon was around 100 degrees. The good news was Buckhorn Campground was open and my favorite water faucet had plenty of water. Plus, the creek in Cooper Canyon was running, so I could cool off and supplement my water.

The trail conditions were virtually identical to those last November, but with heat added. The Three Points — Mt. Waterman Trail was a bit overgrown, and there were many downed trees across the trail. In November there was a particularly inconvenient tree blocking the PCT on the north side of the creek, just west of the Burkhart Trail junction, and it was still there today.

There seemed to be more Poodle-dog bush than back in November, or maybe it was easier to spot because it was blooming. The big winner among the multitude of wildflowers was beardtongue penstemon, which was blooming profusely on some of the slopes burned in the Bobcat Fire. Other wildflowers I saw along the trail included bigleaf lupine, little paintbrush, scarlet monkeyflower, narrow-leaved lotus, golden yarrow, gilia, wallflower, and red columbine.

Because of the trail conditions, heat, and altitude, the Three Points Loop today was more difficult than the 50K I ran two weeks ago!

This high resolution, interactive, 3-D terrain view shows the Three Points Loop (yellow) along with a couple of options (red). The side trip to the summit of Mt. Waterman adds about 1.75 miles to the run.

Yellow Valley Lupine in Upper Las Virgenes Canyon Open Space Preserve (Ahmanson Ranch)

Valley lupine

An unusual amount of annual precipitation not only increases plant populations and growth, it can spawn the growth of plants not usually seen in an area.

On a recent run at Ahmanson, a glimpse of bright yellow along the trail caught my eye. I stopped to take a look and was surprised to find it was a yellow lupine — a variety of valley lupine (Lupinus microcarpus) not usually seen at Ahmanson Ranch.

The last two Rain Years have been exceptionally wet in the Los Angeles area. The result at Ahmanson Ranch has been pronounced, with two seasons of growth, out-of-season wildflowers, and unusually large populations of Spring wildflowers. It’s Summer, and upper Las Virgenes Creek still has flowing water.

Valley lupine is native to California, but in this case may be an escapee from a garden, its seed having hitch-hiked a ride to Ahmanson Ranch.

Cool Temps, Soggy Shoes, and Fast Times at the Malibu Canyon Trail Races

In my experience, there are several things you can count on when running in a KHRaces event — a challenging, well-marked course, well-placed and supplied aid stations with helpful volunteers, reliable timing, good food at the finish line, and plenty of portable toilets at the start. That was certainly the case for the 2024 Malibu Canyon Trail Races in Point Mugu State Park.

The 100K, 50M, 50K, and 30K courses used many of the same trails as those in the Ray Miller Trail Races — including the hallmark start and finish on the Ray Miller Trail. The courses were out and back — which means you get to say hi to everyone in your race and be astonished by the speed of the faster runners.

Cloudy, Cool and Humid Weather

Into the clouds on the Ray Miller Trail.

Ten days before the race computer weather models were predicting the possibility of hot weather, but as race day approached the marine layer prevailed, and on June 8th the weather — though a little humid — was cool and cloudy throughout the day. Here are temps and other data on race day from an SCE weather station near the 50K turnaround near the Danielson Multi-Use area.

A few hours into the race, some runners looked like they had been in a rainstorm. For once, I was well-hydrated at the end of a race!

Water Crossings and Wildflowers

The wettest back-to-back rain years (measured at Los Angeles) in 100+ years had a tangible effect on the race, resulting in numerous get-your-feet-wet creek crossings and stunning displays of wildflowers.

Some runners were determined to keep their shoes dry, but most got their feet wet at least a couple of times. Having run with wet shoes most of the Winter, I surrendered to having wet socks and shoes early in the race. Just about every time my socks and shoes started to feel somewhat dry, another crossing would soak them.

I lost count of the stream crossings on the 50K course, but using Google Earth imagery from May 2023, it looks like there were around 12 (times two) crossings in Sycamore Canyon, plus a few more in Wood Canyon.

My hands were wet most of the race and the only wildflower photo I took was of a striking yellow mariposa lily along the Guadalasca Trail. During a training run on the course in May, I took this photo of wildflowers along the Wood Canyon Vista Trail (Backbone Trail). That was a sunny day!

Fantastic Volunteers

In many ways, volunteers make the race, assisting and encouraging runners in any way they can.

Phenomenal Performances

With the cool weather, there were some very fast times. Scott Traer crushed the 50M in 7:07:43, and Osvaldo Cerda flew through the 50K in 3:52:17! Paul Sinclair successfully defended last year’s first-place finish in the 100K with a time of 10:22:31. In the 100K, Angela Avina was the top woman and placed third overall with a time of 11:08:20. Zac Campbell and Jess Illg were the top man and woman in the 30K.


My run went about as well as any 50K I’ve done. I had no issues during the race and felt good at the finish line and afterward.

Runners don’t expect a course to be exactly 50K — 31.1 miles — and the distance varies from race to race. The longest “50K” I’ve run was nearly 35 miles long and the shortest about 29 miles. My track for this race was just over 32 miles.

Here is an interactive, 3-D terrain view of my GPS track from the Malibu Canyon 50k. The initial view is zoomed in on the Guadalasca section of the course, but the view is easily changed using the control on the upper right.

All the results can be found on Ultrasignup. PAKSIT PHOTOS did a fantastic job covering the race. Their photos can be found here.

Many thanks to Keira Henninger and KHRaces, all the runners, and especially the volunteers for an excellent race!
