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

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!

Goldfields, Silt Slides, Oak Leaves, Invasive Thistle, Rough Trails, and a Reminder to be Watchful

Goldfields blooming on Lasky Mesa - March 2024
Goldfields blooming on Lasky Mesa

Following are some notes and photos from runs in Upper Las Virgenes Canyon Open Space Preserve (Ahmanson Ranch) during March 2024.  Spring is here! The hills are green, goldfields and other wildflowers are blooming, and Las Virgenes Creek is flowing.

Goldfields and Other Wildflowers

The first goldfields (Lasthenia gracilis) of 2024 began to bloom on Lasky Mesa at the end of February. Now, bright yellow patches of these “belly” flowers are scattered across the mesa, adding a brush of color to the roads and trails of Ahmanson Ranch. The cheery flowers usually disappear with the first spell of hot and dry weather. Looking ahead, more rain and cool weather are forecast Easter weekend, and extended temperature outlooks are mixed. Hopefully, the goldfields will be around for a few more weeks.

Some other wildflowers are also blooming. Blue Dicks usually flourish following a wet Winter, but this March are less widespread than usual. Red maids are also less numerous than normal and their flowers somewhat smaller. The elegant white flowers of Catalina mariposa lily are just starting to bloom.

Thanks to T.S. Hilary’s false Spring and copious Winter rain, the hills of Ahmanson Ranch have been green since early October.

Silt Slides

With all the rain, small, shallow mudslides have been common along road cuts and other steep slopes of Ahmanson Ranch. The area has fine-grained silty soil. When saturated, it can generate a slurry of silt and debris. The numerous scars on the hillsides suggest this is a primary mechanism of erosion in the area.

Valley Oaks

After losing their leaves in December, the Valley Oaks at Ahmanson are now budding and sprouting. Some trees already have new leaves, while others are still bare-limbed. The period valley oaks are without leaves varies from year to year depending on rainfall, temperature, sunshine, and other factors.

Invasive Milk Thistle
Milk thistle in Las Virgenes Canyon

Milk thistle thrives during wet years, and it’s been very wet. We’ve had two consecutive wet years, plus a tropical storm thrown in for good measure. The invasive is sprouting in areas where it doesn’t normally grow and growing prolifically in areas where it is established. In a few months, milk thistle may look like it did in May 2005, following the record 2004-2005 rain year.

Rough Trails

Profuse rainfall is a two-edged sword. It revitalizes the ecosystem, turns the hills green, recharges the creeks, preserves the trees, produces wildflowers and more. But it can also be problematic — triggering slides, washing out and damaging trails, and promoting plant growth that chokes trails and increases the fire hazard.

At the moment, the roads and trails at Ahmanson are a bit rougher than normal, particularly in East Las Virgenes Canyon. Use and drier weather will gradually smooth out the ruts and rugosities, but we’re going to be picking foxtails from our socks for some time to come.

Upper Las Virgenes Creek is still flowing — including in the canyon’s upper reaches. Sometimes, there will even be a log or two in place to help keep your shoes dry.

And A Reminder to be Watchful

I sometimes stretch at the info kiosk at the Victory trailhead before running. Today, as I placed my hands against one of the kiosk posts and started to stretch, I glanced down. Disturbingly close to my feet was a small snake. Adrenaline flowing, I checked the head and tail and then checked them again. I stepped back and began to breathe. It was a gopher snake. But it could have just as easily been a rattlesnake. In fact, later on that run, I encountered a baby rattlesnake. That day and the next (March 20 and 21), I saw a total of four gopher snakes and two Southern Pacific rattlesnakes.

Caught in a Thunderstorm on Rocky Peak

Sun and gathering clouds on Rocky Peak Road

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.

Wonderful Wildflowers, a Seasonal Bridge, and a Cranky Rattlesnake on the Bulldog Loop

Update May 5, 2023. Did a run this afternoon in Malibu Creek State Park and the seasonal bridge across Malibu Creek on the Crags Road Trail is back in place!

As I approached the M*A*S*H site, I could see some people taking photos. I stopped to say hi, and without skipping a beat, one of them asked, “Did you wade across the creek?”

He was asking about the creek crossing where Crags Road crosses Malibu Creek upstream of Century Lake and east of the M*A*S*H site.

There’s a substantial log spanning the creek at the moment, and I wanted to answer that I danced across it with my eyes closed. But instead, I explained that I decided to wade — and for sure keep my phone dry — rather than take a chance of falling uncontrolled into three feet of water, ker-splash.

Speaking of which, this morning, I talked to a mountain biker who saw the bridge pulled off to the side of the creek before any flooding had occurred and thought it may have been hauled away. Good news! According to the Malibu Creek Docents, the bridge is seasonal and was designed to be portable. It was removed and stored before this Winter’s rain. It is expected to be reinstalled when the threat of flooding is over — which should be soon.

After crossing Malibu Creek and before continuing to the M*A*S*H site, I took a quick detour on the Forest Trail. Bordered by Century Lake on one side, and steep, rocky slopes on the other, the Forest Trail has a character all its own. It’s a wonderful place to observe, reflect, and enjoy nature. It’s also home to several coast redwoods. Unfortunately, less than half the trees originally growing along the trail survived the 2011-2015 drought. This morning, a redwood that died several years ago had fallen and was partially blocking the trail near its halfway point.

As has been the case in most of Southern California this Spring, the wildflowers on this run were spectacular. Canyon sunflower was particularly prevalent, with many thousands of the bright-yellow blossoms covering the hillsides burned in the 2018 Woolsey Fire.

Also exciting was my first rattlesnake encounter of 2023. I was running down Castro Peak Mtwy Fire Road from the Bulldog “T” when I saw something in the road that looked like a partially exposed root. As I neared, I could see it was a very dark — almost black — Southern Pacific Rattlesnake.

The snake was stretched out straight on the road, basking in the sun. As I approached, it did move, and it did not rattle. Usually, snakes in this state are pretty docile, and I can cautiously walk a few feet behind them. Yikes! This one was super-aggressive. In the blink of an eye, it turned and moved toward me, doubling back on itself. I jumped a mile! It coiled but still did not rattle! It must have recently emerged from its Winter hideaway.

Here are a few photos (primarily wildflowers) taken on the Bulldog Loop.

After the Bobcat and Station Fires: Three Points Loop Around Mt. Waterman (Slideshow, 3D Terrain Maps)

Mt. Waterman Trail

Most of the time, when I do a trail run in the San Gabriel Mountains, it starts from a trailhead along or near Highway 2 — Angeles Crest Highway.

There are many fine point-to-point and out-and-back runs along Hwy 2, but not very many loops. Of the handful of loops that are currently open and accessible, two start and end at Three Points.

One is the Three Points – Mt. Hillyer Loop and the other is the Three Points Loop around Mt. Waterman. The Three Points – Mt. Hillyer Loop was not affected by the Bobcat Fire and is described in this April 2021 post.

On the other hand, significant parts of the Three Points Loop around Mt. Waterman were burned in Bobcat Fire, and the trails that comprise the loop were closed until April of this year (2022).

A large area on Mt. Waterman was burned by both the Bobcat and Station Fires. This can be seen in this interactive, 3D terrain view of the area. The Bobcat Fire is yellow and the Station Fire is red. Where they overlap near Mt. Waterman is orange.

The Three Points Loop is the loop I do most often in the San Gabriel Mountains. The basic loop, not including the side trip to the summit of Mt. Waterman, is about 20 miles long and has about 4000′ of gain/loss. The terrain and trails are varied and interesting, and Buckhorn Campground is conveniently placed near the halfway point of the course. Water is USUALLY — BUT NOT ALWAYS — available when the campground is open.

Doing the side trip to Mt. Waterman adds about 1.7 miles and 350′ of elevation gain. The side trip to Cooper Canyon Falls is even shorter — only about a quarter-mile.

Fire perimeters and burn severity maps don’t tell the whole story, and I’ve been curious to see how the area was affected by the Bobcat Fire; how the Station Fire recovery is continuing; and how the area burned by both fires has fared.

Here is an interactive, 3D terrain view of the Three Points Loop. The map can be zoomed, tilted, rotated, and panned using the navigation control on the right. Track and placename locations are approximate and subject to errors. Poor weather and other conditions may make this route unsuitable for this activity.

This slideshow includes photos from the August 2022 run of the loop, as well as additional information.

Another Triple-Digit Sunday

Pt. Mugu State Park from Boney Mountain
Sycamore Canyon, Laguna Peak, and the Channel Islands from Boney Mountain.

Update on August 17, 2022. As of today, my West Hills weather station has recorded a high of 100 degrees or higher for 12 consecutive days. 

It was another triple-digit Sunday. Once again the high in the west San Fernando Valley was forecast to hit one-hundred and something. I’d hope to beat most of the heat by getting an early start and running where it wouldn’t be quite so hot.

I hadn’t been able to get out to Stoney Point Saturday morning, so was looking to do a little easy climbing as part of my Sunday run. I was considering three options: Topanga Lookout Ridge, Strawberry Peak, and Boney Mountain.

While none of the three are difficult by rock climbing standards, all require the use of handholds and footholds, good route-finding skills, and good judgment. It is entirely possible to fall on any of them.

The Topanga Lookout Ridge loop is about 8.5 miles long with 2000′ of gain/loss. There are a few short climbing segments on the crest of the ridge that can be accessed from the  use trail.

The basic loop up the Western Ridge of Boney Mountain and over Tri Peaks to the Backbone Trail and back to Wendy Drive is about 15.5 miles long with 3400′ of gain/loss. It is longer and more difficult than  the Topanga Lookout Ridge loop.

The loop over the top of Strawberry Peak from the Colby Canyon Trailhead is about 12 miles long with 3100′ of gain/loss. There is some class 2/3 climbing on the west side of Strawberry, and it is essential to stay on route. There have been a number of rescues of those attempting to climb the peak.

It was a few minutes past six when I pushed the start button on my Garmin and jogged down the hill from the trailhead at Wendy Drive. I’d run about a half-mile when I heard another runner behind me. We chatted for a couple minutes and I learned he was preparing to do the Wonderland Trail around Rainier and then the Bear 100.

We were both going to the same area, but by different routes. I was climbing Boney Mountain’s Western Ridge and then working over to the Backbone Trail. He was doing an out and back to Sandstone Peak via Upper Sycamore, Sycamore Canyon, and the Backbone Trail. We would run into each other again at the Danielson Multi-Use Area on the way back to Wendy Drive.

As always, the climb up the Western Ridge (Mountaineer’s Route) was enjoyable. The rock climber in me always wants to check out potential lines, but this morning there wasn’t much time for that. The longer it took to get up Boney, the hotter it was going to be later in the run!

The temperature was already in the eighties when I reached the Backbone Trail. Before the fires and floods of past decade,  the run down the Chamberlain segment of the Backbone Trail was one of the better running descents in the Santa Monica Mountains. From the Tri Peaks Trail junction to the Old Boney Trail it drops about 1500′ over three miles. Today, except for the stretch of trail near Chamberlain Rock, it was nearly back to its original form.

As in other areas of the Santa Monica Mountains, the effect of the heavy December rains was evident. The red shanks, and chaparral in general, seemed to be greener. This year there is a bumper crop of holly-leaved cherries, which must make the coyotes happy. Unlike last year, it looks like there should be some Christmas berries this Winter, since a number of Toyon were covered in green berries.

On the way down the Chamberlain Trail I started to fret that the water at Danielson might not be turned on. The water faucets in Sycamore Canyon are usually dependable, but on a run a few years ago the water system was turned off for servicing. Or what if there had been a drought-related water supply issue?

It turned out the water was still on, and I drank a lot of it. The remainder of the run went well, although I was a little surprised that the sensor on my pack recorded temps in the nineties in Sycamore Canyon. I had expected the south-facing stretch on Danielson road to be torrid, but a nice breeze kept the temperature tolerable.
